Once again we're missing a whole new generation of data hungry applications. Yes, many of us have been suggestion (for more than a year and a half at least) that we should position ourselves (MV) to jump under this larger umbrella NoSQL (Not only SQL or yes-no-sql or in some cases No SQL). The MV products are some of the only ones in this arena that are proven. The problem goes way below the non-adoption of the NoSQL movement. It's a consistent stale state of emerging and adopting technology. Most of this is driven by shrinking customer bases and therefore a lack of revenue to justify seemingly unjustifiable new development that can incorporate the _required_ technologies. Look how long it took to get industry-wide HTTP support in MV. It should have _never_ taken that long to get enterprise stability in the web world. .NET is just now catching on as a major investment for development framework? While there are still new methods of data storage and retrieval being created all the time, the MV market needs to define a consistent web service / REST API for data access and rule execution, accessible from any client. Any clues on how to get any standard that all MV vendors would deploy? I'm thinking this would require third-party software and, even then, the vendors might have better solutions for anyone not needing a cross-MV-platform solution (most users of MV systems do not require such). Been there, done that and saw no interest. It will take code soldiers willing to consistently rush the lines and bash down the doors at all of the DB vendors until they realize that we aren't going to stop until we get what we want. Before that happens, though, there has to be an adopted RFC to define how the comm happens and gives granular detail that can not be misinterpreted by anyone implementing it. Once that is done, it's a matter of building wrappers and interfaces for all of the popular languages. Want the unfinished scrap of an MV ASCII protocol RFC I started back in 2002? More importantly are there more than 3 developers out there willing to suit up and then actually spend time building a language hook? (That's easy, I have done this many times for various projects and for most MV platforms.) From there, professionals in this community can position as experts to provide applications, DBMS support services, rules in BASIC, hosting, and mentoring for a new generation of people who might like to use BASIC for rules rather than Java, Ruby, Go, or whatever else they're just starting to learn. Yeah... as if... Yeah, I don't see it going that route. I do think we could possibly pop up a bit more into the NoSQL playground as an industry. The name is a tad bit unfortunate, but the idea is a good one. --dawn GlenB ___ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users

We use Uniobjects on our web servers to access our Unidata servers. Technically we could avoid UniBasic with Uniobjects, although I don't recommend it. It has makes more sense to push the database logic to the database server using Unibasic routines called by Uniobjects. I'll interject that there are two discussions going on here: language bindings outside the DBMS, connecting in via whatever pipes happen to be available (UO, C, Intercall, sockets, etc), and language bindings built into the DBMS alongside BASIC. I'll go on a limb and state my belief emphatically that we will never see another new language implemented within the DBMS itself. (The only other language I've ever seen built over MV was RPL (PQN+), which is now only available for D3 with variants in jBase and Reality). The DBMS vendors have no motivation to undertake the massive effort of creating a new compiler and runtime to operate over the DBMS engine. Claims of new sales potential with mainstream languages can't be substantiated; We obviously already have external bindings and MV sales have never spiked because of it. Now, as I've said recently, we can immediately build our own external language bindings with no help from any of the DBMS providers. Unfortunately this option leaves us to connect in via the above methods, and no matter how fast that happens, it's subject to a performance hit. A much more elegant solution would be an API that dynamically links with the DBMS monitor to perform direct read/write/call and other operations. Maybe someone can tell us if the UO server component really is this closer to the metal interface, but it's always seemed to me that even that server component is one step and a performance hit away from direct DBMS access. With such an API (and direct access for file open/read/write, etc) just about any language can be implemented inside the box, again with no help from the DBMS provider(s). I'm guessing we could count on two hands how many people might actually be intensely interested in any of this. T As an end-user developer, you probably won't find much interest. There's too much to do with the core business code as it is. Would it make life easier for the few solutions developers who actually might want it? I know I've wanted similar gut hooks for my own oddball projects but I have always found a way to make things happen without it. Just because we're clever enough to connect points A and B, though, doesn't mean we should simply accept that the steps involved always be convoluted and the process numbingly inefficient. Do the DBMS vendors not care about making the solutions-providing developer's lives easier? Who really sells their product? How many forward-thinking developers have left MV because these should-haves never have existed. How many migrations have happened due to a small subset of those must-haves have popped up in another flavor?

Re: [U2] Server Socket logic
I was not aware that you could pass file handles between phantoms and process or other phantoms. That's a no-brainer for Linux fork(), but in most of the MV socket services I've implemented I either: 1) use an inetd/Winetd tool to handle the socket-based muxing and all you have to do is make simple command-line calls to routines(or a single service program). They use stdin/stdout via normal keyboard and screen I/O. Gotta be careful with local echo, though. 2) Have the client first connect to the master (accept()ing process), get an available client phantom port from the pool and then reconnect to that idle phantom on that specific port# to handle the request. #1 makes the solution the easiest to code for and expand, IMO. #2 makes worker management a primary headache but it can all be kept inside the environment. Both solutions can either serve multiple applications from one port based on request data or they serve specific apps on different dedicated ports. A third option is to use request/response file queuing and what ever media type you feel comfortable with. Check out MVWWW on SourceForge for an idea of what I did there. It takes a little more leg work and the interesting(and potentially insecure) feature is that you can easily inject requests and hijack responses at the cross-roads using pretty much any tool at any layer. Local sockets aren't technically any safer, mind you, but it's much much simpler to get a text file into a directory than to spoof network packets.

Re: [U2] Code 128 Soft Font
Bob, Let me also extend an offer to help with general development off-hours, if you're willing to work with GPL libs for open development. I'm sure Artifex will be happy to work out a commercial distribution deal for their Ghostscript offerings. I've dealt with the GS devs on many occasions for both the GPL Ghostscript libs and the XPS/GPDL stuff for PCL, where I've found bugs. They are troopers in that regard. My time is limited @home and I don't have time @work right now to devote to co-developing something, but I could really use a PrintWizard product on our RH server. HTMLDOC is far from a perfect solution, but it's getting the job done right now. As Anthony has stated, I would rather have a local app running on an existing server than go through the hassle/time/expense of configuring yet another critical Windows machine. We will be using it extensively company-wide so it needs to be a fast and rock-solid solution from the power plug in the server it's running on to the PDF being sent via sendmail. I'm sure your customers have never had problems, but based on my previous experience with Windows updates and service pack conflicts I can't take chances with something like this. A perfect example of why I don't care for Windows as a server; I've been forced to hunt down a copy of Win2K3 SBS because FedEx has yet to certify their shipping server app on 2K8. I came - - close to dumping an entire shipping solution due to the OS version requirements and availability tied on by a third party as large as FedEx. C'mon, how long as 2K8 been out?! I've found one application, which I obtained back on RH7.2, that does not run properly on RH ES5. I don't want to get into a Linux/Windows argument, but the fact is I love Linux for core processing and it'll take a major business upset for me to even consider moving something as critical as global document gen to a Windows machine. I have no quarrels with using Windows as a desktop OS or even as an interim data processing platform as long as my approval stamp isn't on it. :) BTW, TRUSTPrice has retail 2K3 copies with 5 CALs for around $500. They're legit copies, or at least mine is.

There are drawing and publishing libraries out there that will do what you want and produce vector or raster imaging depending on what output you're attempting. You can then reformat that using other tools/libraries. The Ghostscript libraries are very powerful and there are a lot of format, or device, output options included. The key with the GS/GPDL library is that everything gets processed as vector graphics. It is, afterall, based on Postscript. Bitmaps are not handled that well, so PCL output can get bloated. The GPDL library is getting better for PCL2PS conversion, but it's still not perfect. I would note that your best success will probably come from generating Postscript content in your tools and then leveraging the GS libs to output PCL, inkjet, jpeg, etc output. I also suggest you stop by #ghostscript on irc.freenode.net and chat with the devs if you're looking for a Microsoft-like drawing and formatting library replacement.

Re: [U2] Credit Card info
Typically, the last four are unique amongst corporate cards under a buyer who may buy for different departments or facilities with different departmental buying cards. They all are issued by the same bank so identifying a specific charge later is hard to do if you don't know the auth code and the last four. We run across this often with SmartPay 2 cards for the US Gov and related firms. There are 4 issuing banks for all of the cards so it's not a good idea for us to use the first four. Even then it can be difficult to do if the charged amounts are the same. We store card meta data in the orders to help with this, instead of being forced to sift through a batch report of hundreds of charges per day. Glen On 1/16/2010 6:37 PM, Anthony W.

A compromised credit card number is no good without other data including name, address, zipcode, phone number, etc. If you store the card ID in pieces, and encrypted, and separate from this other data, then even if the environment is compromised, the only person who could make use of the data would be someone who is intimate with your code and file structures. That was something I was thinking of. I saw on Risks where somebody discussed this print only the last four digits of the card number. I *think* actually, that's NOT what you should do for credit cards. The reason is strange, but makes sense ... Certainly with Barclaycard/Visa, the *first* four digits are pretty much constant per the issuer. It's the last digits that vary most. So if you only display the *first* four digits, you will give enough info to the card owner for him to identify his card, but any attacker will only be able to identify the bank that issued the card. All Barclaycards, for example, begin with 4929 iirc (or they did, I think there are a couple of other variants around now). Other cards are, I gather, the other way round. That article on Risks was how people who didn't understand WHY a particular 4-digit group had been chosen, arbitrarily changed it and thereby actually undermined the entire security behind the idea. The danger is if different people print different bits of the number. An attacker can then put the whole number together from different printouts. Either way, if you're going to print 4 digits, DON'T pick which four at random or because someone else says this is the four. Ask yourself WHY pick that four, and there's a damn good argument which tells you which set to pick, and it isn't just because they're the first, or the last.

Volunteer projects can be rolled out with better browser support than currently demonstrated. The problem with relying on a specific browser's features is the fact that you end up building an app with lots of mods later that can become troublesome to debug and fix when the mods start affecting each other. Rushing a project to fruition solely based on IE's features is not a great way to demonstrate any public web app IMO. I have to agree with the poster's comments on that fact, but I also don't think it's proper to point fingers and name development methods if there are no facts to reference. They need the feedback on what is not working correctly so it can be fixed. The editorials... Not so much. Relying solely on IE's non-W3C features is the first bug. If this is an intranet app, then use whatever you want. If this is to be a public bug reporting tool then perhaps the initial approach is not the best one.

I have no interest in seeing any volunteer project fail, as I've seen plenty of my own get buried in the bit bucket from a lack of interest and/or lack of vision. We need to be realistic here, though. Chrome, Safari, Opera, and Fire Fox are just as popular as IE and are the preferred or only browser available on many desktops. Luckily, there is a fix for Fire Fox. What about all of the Mac users, though? Chrome is growing in popularity as well, so it can not be ignored. Look at the iPhone's explosion. It has Safari, not IE. Would it not be nice to be able to submit bug reports and feature requests from your iPhone, waiting at the airport? The same can be said for all web-capable mobile devices that don't run some mobile version of Windows, which is a large percentage. This browser incompatibility issue rings oddly familiar, reminiscent of applications throughout history that only worked properly on Wyse50's or some other CRT. Anyone remember PROF on the old Reality systems? Early releases of that product were the poster child for terminal incompatibility (pun intended). And you know what? We worked through all that. Yeah, we ended up using emulation software that could handle them all. A decade later the web grew up and became useful for businesses. There are browser emulators available, but the only people that really use those are web devs. I just don't buy your logic here. Now we're faced with different terminal emulators going by the names of IE, FF, Chrome, Opera, Safari, and a few others. Sure, the whole connection method has changed - stateful telnet going the way of stateless http - yet at the most fundamental level, it's all just bits on a wire talking to some device on the other end. Too simple, you say? I disagree. It *is*simple. It's the same problems we've addressed before and that we will address again and again as the technology landscape evolves. The difference here is that there _is_ (and has been for a long time) a standard and it's called W3C. There is no incompatibility unless you develop outside of the W3C standards. AJAX and various other Javascript-based development methods (JQuery is great!) can work with all W3C compliant browsers if the standards are followed. Some extra coding is required and some features may have to be dropped or simulated using other methods to implement the desktop-like features users want now. Heck XHTML is the standard now and all of the mentioned browsers support it along with AJAX and CSS. I think even Konquerer will properly run AJAX sites, provided the site doesn't use IE-only features. Having established this context, I do have concerns about the premise that we need Microsoft technology to do the web properly or that Microsoft technologies give us something that we couldn't get any other way. Of course, the same could be said of IBM or Oracle or ... name any company here.

RE: [U2] PDF printing, LaTeX, Ghostscript, etc.
Doesn't using PrintWizard imply the use of a Windows server somewhere? If not, then can you provide a link to your Linux version? I've looked your offering over several times and end up considering other options simply because I already have too many disparate servers forced to perform individual tasks due to vendor requirements. I'm hoping I missed something. I'm not yet at the virtualization point since one power supply has 10X higher of a chance of blowing up than 10 power supplies.

Of the top of my head, a locking service would be a U2 subroutine listening on a particular network port that is started/stopped along with the DB. Your client routines would use the socket functions to connect. The nice thing is you get the duplicate connection handling for free. U2 socket listeners are not multi-threaded so the first client in gets the socket. As long as you hold it for 1 clock tick before closing and have the other clients on a time-out longer than 1 clock-tick, you should get your unique keys. There are other options and they all have been tested. A master service phantom responds to all initial requests with a port# to connect back on. The client reconnects from the master over to the client phantom on that port. You can have X client phantoms handling the actual processes. That provides multi-client service, but it provides it at the cost of reconnections. I utilize a file-based spooling architecture in conjunction with inet/Winetd sockets in MVWWW to avoid this reconnection scenario, but that does have performance limitations. I did mention this was over-kill right? It's not overkill if you need a multi-app/multi-process service that offers a single source for sequential keys. The other option is disk file locking. Any way you look at it, you have to go to one place for the key. Don't relay on O/S random numbers either. Even those are flawed at high resolution. Although the code itself is pretty simple and, in my experience on Unidata, the U2 sockets routines work very well, I would spend some time benchmarking to make sure this kind of effort is worthwhile. Assuming you have some spare server capacity, if the phantoms are using a lock file on a frequent basis, the file will likely be in cache anyway. HTH but probably not.

RE: [U2] Guaranteed unique sequential keys
You'll need a central key generator to manage high resolution sortable sequential keys. You can use whatever connection medium is feasible and let a single process/phantom generate the keys in numerical order. The problem with using a key generator like this is that you could easily produce a bottleneck. On the other hand, the benefit of doing it this way is that the generator can be a single phantom. It can keep track of the last used key in memory and can pregenerate keys for near-future or parallel usage. If the connection medium you choose allows for multiple requests at a time, then your management code must be able to manage and pregenerate keys for each thread concurrently. A wide solution could be a socket service that serves unique keys to clients. I use base-16 for a lot of sequential keys so that I have many unique iterations per key length. I always use them as direct pointers and I never sort them, though. Hex sortability from LIST/SORT/SELECT could be questionable.

RE: [U2] Steve Cashman
It's not as simple as you might think. There have been long heated discussions about how to deal with vacation auto-responders on lists - including Majordomo. In the end, there's 2 options: 1) A subject filter that drops all messages with out of the office and away on vacation somewhere in the subject. That will also kill real postings with the strings in them. Also, various away responders may have different subject styles so the rules you implement may only work 50% of the time. As the list grows, the chances of a variety of vacation clutter grows. 2) The second option, which is typical for people who openly use mailing lists, is to set up your auto-responder to not send 'away' replies to e-mail addresses that are mailing lists. That can be done with partial address matching or by specifying the e-mail addresses manually. It only takes one step, by you or your mail admin, and it's dealt with for good.

Tony Gravagno opined... Clients need to know the port of a server, so a server absolutely requires a fixed and well-known port. A server can have a randomly assigned port that is fixed and well-known only between the client and the server. If the server only exists for the benefit of one client, it is up to them to figure out how to assign and communicate the port dynamically. The fixed and well-known port requirement does not imply that the assignment is permanent. FTP transfer is a good example of a dynamic port assignment. Client commands are passed through server port 21, while the file data is sent to the server through a dynamically spawned transfer service on a dynamically assigned port. Why do you need an assigned port for a server? Think about the problem of a client needing to spawn a unique server on demand of the client. Each client may spawn a server dedicated to that client. Certainly if one were using real UNIX/Windows processes, one could single-thread through a central process and fork a new process, however, U2 products do not allow forking of processes. No MV products can share the same user heap through forking or child threading. If you want some options for socket services with MV, e-mail me directly. execv() is a possibility using a C call, but it's not a fork or thread solution. I don't want to flood the group with a bunch of potentially meaningless text. 2) The other issue with the initServerSocket() is that it does not recognize when another process already has a given port open for listening. I haven't read the specs for initServerSocket but if it doesn't return a non-zero for an attachment failure then yes, it's probably broken. Yep. However, in general, a given service should only have one listening process. Not always true. There are dynamic services too. FTP once again is a good example. It is valid to have a range of ports which all respond to inbound connections as a single service - that is, multiple servers will be listening to different socket ports, even if they support the same application/transport service. Interesting idea but it does not help with this issue. Have you tried supporting multiple listening sockets in U2? You can not get anywhere without a select() or poll() function analogue. While one could spawn numerous phantoms, each listening on a unique port, one is left with how to coordinate data and such between the phantoms. Not a pretty solution. No, it's not, but there are ways around this using external pooling. Like I said, e-mail me. JD3 is a good example of a phantom pool, but phantom pooling requires a lot of socket reconnections and that just puts unneeded load on the network sub-system. It's a stable design, but I personally don't like that architecture when there is a stream of short-term connections. Coordination of what ports are in use for a given service should be done by the application, so you should never really get to a failure in initServerSocket. Try the replication program using port 80. On my system initServerSocket returns success even though IIS is currently bound to that port. If nothing else you can use netstat to see what ports are in use and use a recognized port that is unallocated. Yes, but not a solution for this issue. Again, if you randomly generate a socket port for a service, how will any client know what port to connect to? They communicate the port number behind the scenes. broken recordFTP/broken record Good luck. Tony Gravagno Thanks, Tony.

RE: [U2] XML and Accuterm
Interesting. If you have a registered ActiveX or DLL, then you can create an instance of it using 2K and 2K2's VBA scripting. You also will need documentation on the methods and elements that the object contains. I've been using 97 for many years now, so I never knew about that. I just recently upgraded to 2K2. Thanks for the info. So, there is a possibility to use an ActiveX object that can post and retrieve XML documents. The white paper is specifically for integrating Accuterm into Office, with a focus on Outlook. In order to post and retrieve XML documents, the ActiveX control or DLL will have to do that behind the scenes. Maybe there are some free or non-free controls out there specifically for that.

RE: [U2] XML and Accuterm
Why bother with Accuterm? You can do what you want straight from the command line using BASIC. I'm pretty sure that Accuterm has no capability to perform socket connections using scripts. It has VBA(Visual Basic for Applications) capabilities, which is nothing like VB. You could write an XML bridge in VB or VC++ and then load it. Using a DDE server in the application, you can post DDE client requests from Accuterm to the application using VBA calls. However, that's like building a speed bump out of glass. It'll do the job, sort of, but it'll end up breaking at some point and cost way too much time and money to build in the first place. Here's a (extremely trimmed) UPS XML tracking example I've done with cURL and directory Q-pointers under D3. Took me about 30 minutes to implement it. tbuffer=fill in this with the XML request header and document open 'tmp' to tmp.f else stop filen=tracknum:rnd(100):.txt write tbuffer on tmp.f, filen CMD = '!curl -s -H Content-type: text/xml https://www.ups.com/ups.app/xml/Track -d @/tmp/':FILEN EXECUTE CMD CAPTURING OUTPUT EXECUTE !rm -f /tmp/':FILEN CALL XMLPARSERSUB(OUTPUT,ELEMENTS,'0') LOCATE TrackResponse.Shipment.Package.Activity.Status.StatusType.Description IN ELEMENTS1 SETTING VM THEN PACKAGEACTIVITY = ELEMENTS3,VM END Since curl runs on just about all platforms, this is a cross-platform solution.

RE: [U2] [OT?] SATA vs SCSI drives
This totally depends on the chipset manufacturer. A $50 Adaptec SATA card isn't going to burn a hole in the case. Our Opteron file-server box is running a 320GB Barracuda RAID 5 on a 64-bit 3ware controller. It smokes every Adaptec SCSI RAID I have on site with ~500MB/sec read throughput and near 300MB/sec write over FTP on a 100MB full-duplex switch. For the best money/speed, SATA RAID is the way to go. For the overall best in speed, consider a multi-channel high-end SCSI system. Fiber is definitely the cleanest, but it's not cheap. A few thousand in drive hardware costing and you'll probably end up reviewing and comparing SATA again. :P But hey, if you've got the money, go full-blown 64-bit multi-channel SCSI. Keep in mind that when a 200GB drive dies on a SATA array, you're only out $150-200. Compare that with lower capacity 15K RPM SCSI drives running $400-$600.

RE: [U2] pcl to pdf converter
A direct PCL to PS conversion is dirty and mangled. You may or may not get exactly the same results between the two on their respective hardware. Ghostscript is free and will do a good job, for a huge range of conversions on *nix or Windows. I highly recommend using it to get your initial design and testing done for the documents. If you want to pay for a shrink wrapped package, then make sure you know exactly what you are getting out of it. Send the vendor some sample PCL and have them e-mail you the PS/PDF results. A custom PCLPS filter is usually employed and everyone writes theirs differently. You may be surprised at the quality drop when you convert a raster based PCL document into a vector based EPS/PS/PDF document. I've been fighting that battle myself for years, converting our old PCL docs into PS/PDF. I've gotten most of our documents stored as HTML templates and EPS images now. html2ps converts them over to PS and I let ghostscript generate PDFs when I need an e-mail or portable file.

RE: [U2] THE variable names
I'm just wondering who comes up with this stuff. Those who use the language to it's most interpretable form. I have seen general BASIC programming instructors focus on the use of non-cryptic, non-abbreviated variables, instead of compact code. Afterall, the pcode generated is the same for THE.CUSTOMER.CITY as it is for CCITY or CUST_CITY. Which can you comprehend the quickest at a glance? You can also parse your own code, if you have a delimited variable structure that is consistent throughout the entire project. All good things, unless you're main focus is keeping the code short and cryptic. I have to agree, though, that THE is not really a useful variable keyword. It does help with programmatic variable identification, though. To each his own. Also, was there ever any lack of faith in the READ statement when assigning the variable REC. I'm now seeing some of this: REC= ; READ REC FROM FILE, ID ELSE REC= I use the else null clause religiously under D3. I have seen numerous accounts of read failures not resetting the target variable. The program chugs along happily with data from a previous read and it eventually blows up for a seemingly unknown reason. The extra null assignment is overkill, unless it exists once at the start of the program to prevent variable not assigned run-time notices.

I'm just wondering what it costs. The best way to find out what products cost is to contact the supplier. Sandritech in particular has a good group of people and I'm sure you'll get good info, product, and service with them. I'm not one to support senseless cloaks of secrecy (I hate not seeing a price tag on items in a store) but there are many reasons to not publish pricing info. Retail and software services are two totally different styles of markets. However, a lack of base pricing will more than often deter prospective customers from inquiring on products. People are lazy these days, especially with the reduction in staff that most businesses are running under. The easier you make it for the buyer to shop and compare, the more likely you will be to get a sale. Do the comparison legwork yourself and post a price comparison by feature. I'll bet you sell more product that way, even if you are more expensive. Make sure you keep it updated, though. There's nothing worse than pulling up a comparison table to see it's 4 years old and the features list is 3 versions old. Pricing for some of these software products can vary widely depending on the VAR, their value-add in terms of support, training, etc, location, bundling, and many other factors. I might offer a well known product at cost if we agree to short or long term services or a training engagement. I might waive support fees for some period of time or offer an add-on component for less than list cost, not to mention quantity discounts. This is always an issue and everyone who is involved with buying software licenses and support understands that published pricing is only a top-level guide, not a real quote. However, published pricing is the only way to narrow down the huge list of software possibilities to those that fit in the general realm of a companies budget. I don't bother calling a small software firm for a price quote, if there is no published base pricing for their standard product. It could be a lot cheaper, but I don't have time to call 20 small software companies and get accurate price quotes to then narrow it down to 2 or 3 that fit our budget and feature requirements. If we let 'list price' stand as any guide by which we judge products then I dare say we'd consider a whole lot of products unworthy of further investigation, and these negotiable would never even be put on the table - I've seen it happen. If you sell any kind of product or service, you must have base pricing. Anyone who doesn't show it should either be the only one in their market or have an established name in the market. Selling cars with no window pricing is fine because you can touch what you are comparing and you can always pull out the Kelly Blue Book to see what the base prices are. You can't do that with software, unless you spend weeks getting quotes for features from every software vendor out there. No one in their right mind will do that, except maybe a consumer reporting group like CNET or a magazine. Typically, though, consumer reports are biased towards the advertisers that pay their salaries. Still, the deciding factor is going to be the overall feature/price point. Companies that know their market and know their price points can show base pricing without pushing away prospective buyers with high estimates or misleading weary shoppers with under-average pricing. A price that's published today may change tomorrow. You don't want to prospects to be discouraged by a price they see in a forum when the price isn't what was posted anymore. Also, sad but a fact of life, many companies use list price as one of their key differentiators to raise or lower their own pricing to find a competitive sweet spot. If someone publishes pricing in a public forum it may mess up the vendor's competitive positioning, and even encourage other vendors to just raise their own pricing - I've seen this happen too. That's because a lot of software vendors do not perform any kind of demographics to determine their price points. If you're going to sell a product in a market with a lot of competition, then you need to know what your min, max, and average pricing should be based on the competition's market share and the products they are offering. If I opened a hardware store next to an ACE store and offered the same products at the same price, then I'd never sell anything. On the flip-side, if I set my pricing 30% lower than ACE then I'd need to sell a LOT more product(lower

In the absence of any suitable remedies and perhaps as a stop gap solution whilst a better solution is written, I would recommend the following: 1. As Martin said, make sure that you do not let UniObjects traffic through your firewall. This cuts down the threat from outside but many hacks come from employees who are disgruntled or just plain nosey. 2. If you don't require UniObjects on all PCs then don't install it. If you do require it, don't install the documentation that gives the user a sample application to copy. Change the standard port used by UniObjects and don't advertise it. You can still sniff out open ports easily. Your best bet is to map port access by IP class range and exclude departments that don't need access. Of course, if the network is all over the place then you'll need to specify filtering by IP. 3. Consider an architecture where the UniObjects client is a separate server (e.g. web server or Citrix server) and users don't require the UniObjects DLLs on their own client. This is also easier to maintain when you upgrade. DMZ setup is still a big part of the equation if you use a remote machine to host a connectivity portal. The only problem there is traceability, if someone where to hack into that box and gain root/admin privs. The same can be said for any box on the LAN, except you won't be looking for oddball IP-based activity if it's all coming from one machine. :P 4. In addition to application security, make use of OS security. For example, if your HR system is only used by a handful of people, don't give all your users access to the data files and rely on the application security to keep them away. If they have to steal a password as well as write a VBA program, it is harder than just writing a VBA program. 5. Don't hard code usernames and passwords into your source code! They can be seen in the object code of any application. You can concatenate raw characters together to form a username or password, and you won't be able to easily pull the object code up in hexedit and look for stored strings. You can also use an internal character shifting algorithm to make it harder to dechiper what's what in the object code. 6. Keep an eye on logs and look out for unusual behaviour. Can anyone help me with this? What logs are written to when someone logs in and can you distinguish between a telnet login and a UniObjects login? If you are firewalling the box, then you should be able to log incoming traffic regardless of destination port. If not, then setup a firewall router that can log and report activity. A 586 with 32MB of RAM will run a Linux firewall just fine. Glen http://mvdevcentral.com --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/

RE: [U2] Include Vs Call - Software Maintenance
Functions are only useful when you are returning a single piece of data. Most of the designs I've written take advantage of multiple, bi-directional parameters. If you need to limit scope of the branch to a single local variable, then a function is good way to limit cross-contamination that subroutines can cause. You can still muck things up by assigning the same variable as the parameter being passed through the function. Reusing a variable on the same line is a naughty habit. I try to pinch myself every time I think about doing it. I think that there may be a memory limit, on some flavors, for the returned data of a function. I'm not 100% sure about that, but I think I remember a discussion elsewhere about the pro/cons of functions. I don't see why the call stack would be that different from a subroutine, so maybe I'm dreaming again.

Functions are quite useful in VB (et al) yet don't show up at all in legacy code and don't get that much airtime here on this forum. I've only ran into them once on UD when hooking into Redback. Every time I write a SUB that really is a function in purpose, I tend to name it GET.PRICE or GET.USER or GET.PRINTER etc. So are functions a kept secret in MV programming or has no-one had any issues with them? I'd like to know so I could either get better with them or ignore them and continue with subs.

RE: [U2] UV on Linux
Keep in mind that I'm not a certified Linux engineer. :P The only file I/O problem I know of, with 2.4 kernels, is the buffering issue. All kernel block devices are buffered by the kernel, unless they are bound by a raw device binding. This could be the culprit in the driver's bottleneck situation. Try binding a partition to raw, on that disk array, and then perform some high-speed read/write tests. You might be surprised at the throughput difference. raw -qa lists all bound block devices. I don't recommend raw bindings to be done when neither the hardware, nor the software writing to disk handles I/O buffering. You may end up making it worse. In my case, I have a fast caching RAID controller and D3 has a write buffering system in place. When the kernel jumps in and buffers too, things go wacko and user response drops to between 15 seconds and 1 minute under normal disk activity. That's for 25 users on an AMD 2+Ghz with 1GB ECC. I don't know if UV/Linux caches its own writes and reads. If it does, then using raw bindings should help with disk throughput by eliminating the middleman. Don't hold me to that, though. PS: Changing the kernel file-max will only increase the number of files that can be open at a time. If you have a well trained disk subsystem then it's kosher to do that, because the kernel probably won't have to use swap for buffering. Mine happens to be 104851 and it's been chugging along for a couple years now with no disk I/O problems. When you pound on swap ontop of a continuous heavy I/O load, then you're just begging for a kernel panic. According to the Linux configuration guide, you should set file-max to 256 files per 4MB of memory. 1GB would be (250 * 4MB) * 256 files = 64000 for file-max. Of course, you can tweak that number up until you hit a swap or disk subsystem threshold. Your box should only use a small amount of swap under normal operating conditions. If it is using over 25%, then it's time for more memory!

Everything is fine at the Universe level. We havent had any major issues at all. One thing we used to do to get users off at the end of the night or when needed is to do a 'MASTER OFF ALL'. It doesn't work on the Linux version. Other than that, Universe is peachy. I find that support for Linux is generally lacking. Red Hat support is 'alright'. We have RedHat support thru IBM, which is much better than the RedHat support (IBM is usually a knowledgeable person that speaks English very well vs the RedHat guy who is not always very knowledgeable and has an accent that requires a special hearing device to interpret). IBM support is cheaper too. We keep RedHat for the up2date functionality and the resources they have. It really is a nice way to keep things current. Are you using all Dell Hardware ? We are running an IBM xSeries Server and an EMC Clariion. We are having performance issues with intensive writes to the disk array. There is a minor issue with this when doing the same kind of operation on the internal disks. Intensive disk writes could be an batch application that reads records from one file, deletes and writes to another (say 100,000 records type 30 files with indexes). We do this for archiving data. It could be a linux 'cp' command copying a large file (100meg) to the disk array. What happens is that the system goes into an iowait state and user response is non-existent. Sometimes, the system will hang for close to a minute until the i/o completes. We are also using Qlogic 2340 HBA's to connect the IBM to the Clariion. If you look thru the RedHat Bugzilla, there have been issues with the driver for this hardware. We will be testing out some Emulex cards next week to see if that improves things. If you have the luxury to evaluate your system, definitely try copying some large files or 'archiving' type processes while users are on. Monitor performance with the 'top' command. Then determine if things are acceptable. We converted from a DG/UX box with a Clariion. Performance was never really an issue on that platform and these types of operations would absolutely go unnoticed. EMC has been trying to help with the issue since February. I have to say that their support SUCKS !!! It seems that there is no one there that knows anything about Linux. I am finding this in general. When you mention that you are running Linux, a dark cloud appears. So, you probably will not get the excellent type of support that you might be accustomed to with Solaris. I would assume that you like Dell support ? My experience with them is that they went from once upon a time very good (8 years ago or so) to the pits. Every time I call, I get transferred
RE: [U2] MvInternet - IBM Licensing Requirement
The gotcha there, is the fact that you *know* that 500 employees are using the DBMS simultaneously via 2 seats. If you said, I _know_ that no more than 10 employees are using the software at any given moment and I have 10 licenses to justify that, then there would be no problem. Whether or not it appears that 500 can use it within realistic timing is a completely separate investigation. The truth is, if you only have 10 seats then there can only be 10 active processes on the box at a time. The days of user=process are gone. It's time to wake up and realize the world has changed already. MV is always the last to smell the coffee burning. This thread is really getting moldy guys. The fact is, user-seat licensing and pooled licensing mix together like alcohol and mercury. There's a cost-per-unit sales problem inherent there. Either you loose all your single-seats to pooled muxes or you end up fighting the single-seat mux wars. IBM can try it, but I know it won't work. It's time for a CPU based license model, for those who want to configure MV for a non-persistent services model. There's no other realistic solution.

All DBMS products are engineered to allow us to perform the following sequential functions: Accept connection and query Read state data from cache or disk Perform operation on all data Write state data to cache or disk Respond to user and disconnect This is the way web servers work and one common way of engineering a disconnected client/server model. There is no physical way that anyone process can perform those functions for two users simultaneously, the way two instances of pirated software does. All users must wait for any user consuming a license to disconnect before they consume the license in their own turn. The terms connect and disconnect may imply logging in or simply going inactive as someone else consumes the license resource - the point is that the way MV platforms are engineered, only one user can make use of the resource at any given moment in time. This use of licenses has a long standing legal precedent, here are two examples: Modems which came into use in 2nd to 3rd generation systems allowed one user to connect and then disconnect, followed by another user who did the same. Per-seat licensing, compared to named user licensing has always acknowleged this paradigm. Today, if we choose to allow one user to consume that license for a period of 2 hours before giving it up, or 200 milliseconds, that is a matter of design. There are no set standards for how long a user must consume a license in order to be considered legal, except where software
RE: [U2] Factory Floor Automation - Serial Connectivity ?
You can perform socket connections from UV and read/write directly from/to a TCP service. I agree that Lantronix makes nice equipment. The 802.11b dual-port box would work fine if you had a wireless access point to hook back into the LAN. The question comes down to laying cable or not. I would perform a signal test using a Laptop + PCMCIA card and an access point positioned near a permanent spot, for each area you planned on installing an 802.11b serial bridge. Poor signal = poor/no results = more money for antenna hardware. That's still cheaper than running cable and chaining high-grade switches as repeaters. There's so many ways to go about it all.

RE: [U2] [UV] send data to IP address?
Don't make it so complicated!

It'll print as soon as you send it. If you have a lot of labels being printed, you can have a phantom running that stays connected to the FTP service and transmits a local file spool. Make sure you send a keep-alive note of some kind periodically. Otherwise you may get kicked off for being idle.

RE: [U2][UV] Forcing a port to close
Nick, I looked this up in the socket guide and the syntax is correct. The only real issue that can arise by enabling address re-use is the slim possibility that partial data could be received into the socket buffer, from the sockets that were never shutdown down properly. This can lead to confusion in the application and/or the socket subsystem. I've never had that issue occur, but the possibility of the condition should be known. Just for clarity in future reading, socket shutdown and close are not synonymous. Close refers only to the release of a file handle. A handle can be closed and re-opened on the same socket address. Shutdown refers to the releasing of the file handle and also the addresses used by the socket.

Without this option the system will return error address already in use. This condition is typically encountered as follows: a) a listening server is started b) a connection request arrives and a child process is spawned to handle that client c) the listening server terminates but the child continues to service the client on the existing connection d) then an attempt is made to restart the listening server (will fail with address already in use due to client connection) SO_REUSEADDR also allows two listening servers to be started for the same port no, but specifying different ip addresses (if hosts has mulitple addresses). However we can still only start one server for each ip address available to the machine This is true. I have never heard of the shutdown issue mentioned below. I have been writing socket applications for a long time and use SO_REUSEADDR and have never come across this issue. Shutdown(in my terms) refers to the bi-directional termination of a TCP connection, not just the release of a socket handle. You can also shutdown() a socket, but that only partially closes the socket. shutdown() blocks recv() functionality, while still allowing send(). This is a great method of connection controlling that a lot of coders overlook. I didn't see it listed in the U2 sockets API, but it is available under most programming languages. If you've always used the flag, then CLOSE_WAIT makes no difference. However, if you see a LOT of connections in CLOSE_WAIT on your service port, then you should check your code. Something is definitely not kosher with your child processes. There are some other uses for RO_REUSEADDR which are quite advanced. Reason why close my not shutdown a socket. If a parent process and child process have a socket handle open. In the case of the parent forgetting to do a close on the socket handle after an accept call, then there will be two references to the same socket. When the close is called by the child then the open reference counter on the socket will be decremented but the socket will not be shutdown (as the parent still has it open). The socket will only be shutdown if the parent closes the socket too. This is a common mistake. However if the code is corrected and the parent does close the socket, then when the child calls close on the socket, there is only one reference count to the socket then a close will shutdown the socket too. This also happens when a parent is killed by an interrupt and there is no interrupt handling in the application. The parent bails without cleaning up and then waiting for the children to follow suit. Every child process gets set to CLOSE_WAIT. We are on the same page, but I think I'm writing it in a different language. :P James Glen http://picksource.com http://mvdevcentral.com --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/

RE: [U2] U2 to web software
George, your implementation isn't cludgy by default. It's only slow and cludgy if the processes involved aren't tuned to function with file spooling. The basic design of MVWWW utilizes file spooling much in the same way. I get very good throughput using it. It is not anywhere as efficient as pipes, direct sockets, or shared memory, but it is portable and simple to design around. As with any software design, overall performance is based on the hardware running it. If you have a very slow file system, then your file-based solution is going to really drag. On the flipside, try running a ton of IPC based processes on a system that is heavily swapping to disk. If you fully understand an architecture and what it requires, then there is no reason why it can't outperform a poorly implemented better design. With that said, it's very hard to compare apples to apples, when one of them is apple sauce and the other is juice. I run FlashCONNECT and have been happy with it, with regards to processing time. Unfortunately, it still lacks proper phantom management. My error log still shows many 505 errors when processes get overstepped. To compensate for a large amount of errors, I run a couple more phantoms than is needed. That eats up my seat count, but I don't have any other options. I still see 505 errors pop up now and then. MVWWW may be 1/2-3/4 second slower to respond, but it's impossible for phantoms to step over each other. Phantoms can be added and removed at will, without any service problems arising on the client side. When it's been thoroughly tested and proven, I may be migrating my code. There's always a trade off, when it comes to architectures. This is a general response and probably useless info. I'm no expert, but this is a small tech niche I've been playing in for a long time now. Performance, in regards to architecture, is based on several things. First, there is the client (CGI in this case). Secondly, there is the DB-client bridge. Thirdly, there is the backend application (U2 in this case). How each of these components is designed and implemented determines the performance and flexibility of the architecture. In most cases, flexibility deters performance. The opposite is also true. You can, however, balance the two and get great performance without sacrificing flexibility. Most fast performers utilize a real-time connection across the DB bridge. The CGI client makes a local service connection via IPC(inter-process communication). The local service is already connected across the DB bridge, to a backend service. Therefore, the request time is near zero. Client requests return content to the browser as fast as the backend application can complete. If content monitoring and control is put in place, then performance will decrease. If a request for an invalid app comes in overly often from the same IP, then that IP should be temporarily blocked from accessing port 80,443,8080,etc. Some fast performers remove the DB bridge completely and offer direct client to backend connections. While these are the quickest, they may lack control and recovery capability. A DoS(denial of service) attack can flood the web services and backend to a halt. A good direct solution should always have load control(phantom management) and reliable content monitoring. Flexible implementations can utilize many techniques to handle processing. Most of them utilize modular components to handle each step of the process individually. When you get into complex architectures such as these, the performance is determined by the design of each component and also how well the components work together. A positive aspect of modular setups is the ability to monitor and control content between steps. You don't need an integral content manager. Plug-ins are a breeze to implement. The key to reliable modular implementations is reliance upon well known pre-built tools and services. For example, writing your own operating system socket service can lead to system stability issues. This is especially true if you don't know what you're doing. Also, relying on one specific component to handle most of the work can lead to load problems and possible system stability issues. Launching a U2 shell directly from a web server is an example of dangerous modular implementation. A good rule of thumb is: If you don't fully understand the good/bad of what is being done then don't do it. I don't know the architecture of RedBack, so I can't categorize it. Can someone provide some info on that? CGI is not a method, language, or API. CGI is a common gateway interface. This standard provides a set of operating system environment variables, much like TERM and PATH. Web based services can obtain information indirectly from the web server, using these environment variables and also 'standard input'. CGI environment variables and input content are available to all applications that can be executed from the web

Vance, Thanks for the invite, but I don't repost other people's code. I finally have MV Developer Central up and running. If anyone is inclined to post snippets in the snippet library, or even start an open source project, then feel free to register and post this kind of stuff. The purpose of this site is to offload the code management from PickSource and centralize MV development efforts. PickSource is not really a code repository. It's actually a community portal. MV Developer Central will soon be(I hope) the single spot for MV open source development. I may extend this to include commercial tools, but that's undecided at this point. Tony and I are working on many things at the moment, but most of the site is ready to go. There are some quick-start guides available in the Site Docs area, for those wanting to start a project. A Tortoise CVS quick-start and a WinSCP overview are currently available. They're rough-drafts, but they'll help you figure out how to use CVS and WinSCP with your project. I will be writing a SourceForge project intro doc sometime this week, to inform newbies about SF projects, what they consist of, and how they can be used. A brief synopsis would be: Your own MV focused code publishing, management, and current version system with project web service and an extensive self-service project support center http://mvdevcentral.com I will have a CVS of MVWWW's dataBASIC code published soon. I need to make a couple changes to the code, to make a single flavor-configurable release. For the time being, a D3 pseudo account-save and a QM account directory tar are available for download.

As the clock speed of the SPARC is relatively low compared to a Xeon MP we found that combination outperformed the Sun (and was a lot cheaper once a large disk array was added in). There was nothing that Sun could do to improve the performance due to Universe being compiled against a very old solaris (7) version. Core clock speed, alone, is an irrelevant factor in the overall performance. It typically only makes a difference based on chip architecture, bus speed, memory access, and chipset performance. The Sun box is a RISC platform, right? I'd be interested in your comparison specs, if you can dig 'em up. I'd bet a few bucks that a dual Opteron(2.0Ghz-2.4Ghz) would smoke a Dual Xeon-MP of any current speed. I've never put them side by side with exactly the same peripheral hardware. A Xeon is basically just a Pentium on steroids. Have you looked at the Opteron whitepaper and architecture specs? The potential bandwidth those things have, as n-way configs, is totally awesome. I'm sure even a single 100 series, on a dual-board, will smoke a single Xeon. Check out the 800 series - if you've got a bottomless wallet, you can run an 8-way Opteron. *drool* You can probably imagine what the Sun engineers reaction to that was!

RE: [U2] Universe to Web interface
OK. That's what I thought. UV is in the same situation as all the other flavors. If you can't pass a file handle between processes, then you can't effectively create a multi-client service by using just the sockets API. There have been numerous web/socket architecture examples published, in terms of code and/or postings on C.D.P. JD3 is a Java-focused socket service that uses a port gateway, which redirects(client disconnects and then reconnects) incoming connections from a master listener to 'child' listeners. This is a stable method, which does not require sessions to be initiated. The biggest drawbacks are the reconnect lag, port firewalling issues, and requirement of the port master to constantly keep up with who/what is really running on the MV side. This is considered an internal architecture. No non-MV components are needed. Coyote is an internal HTTP service all in its own world. hat off to Doug FlashCONNECT is an HTTP POST/GET service that has client-side and server-side services running. I don't know all the details of how the 2 services communicate, but the request is sent to a local(webserver-CGI-local) service. That service is already connected to matching services in MV. The communication paths are pre-established, so there is zero lag between CGI request and MV processing. The only problem there is the fact that the communication paths are pre-established. It's a dual-edged sword. Monitors have been added to recent releases, to deal with previous load and license balancing problems. This is the most effective mixed architecture I've seen so far. MVWWW is an open communications framework that utilizes an open mixed architecture. The 2(or 3 if you separate the client component) architecture 'zones' are separate. The CGI(or client), the spooler, and the service zones can be separated and used by themselves for other purposes. This modularization allows flexibility in integration. However, it also leads to security and content management issues. I, as a developer, prefer this style of architecture over mixed or internal-only simply because of the flexibility. RedBack.. hm.. never touched it. One of these days I'll get around to it. I run FlashCONNECT here mostly because I'm still running D3. Times'r changing though. I develop MVWWW on my OpenQM developer box. When Doug releases Coyote for OpenQM, I'll definitely be running it through the hoops too. When someone asks how I do pull MV data using my browser, I like to sit back and watch the fur fly. I lost count of the number of methods discussed for getting MV data into a browser. Maybe one of these days a web-based communication integration wizard will be created. Until then, I wish more of this kind of information was compacted, indexed, and published on the web.

RE: [U2] Universe to Web interface
Stewart, Socket implementations don't work across flavors. I've written many socket apps for D3, but even the small differences in the socket designs between Win and *nix causes problems. Sockets are easy to implement, but only if you want to maintain separate code-sets for Win and *nix under each flavor you want to support. I won't get into the details here, since I'm not familiar with the UV socket API. Service sockets are meant for the O/S, not Pick. Doug Dumitru bit the bullet and wrote his own TCP stack in Pick ASM. That is about the only way I would recommend even contemplating Pick server sockets. For clients, the socket APIs are fine. The calls are nearly identical between Win and *nix. The only issue there is blocking control, which unfortunately most of MV socket developers are unknowledgeable of. OK...I'm not going to get into that... meditating The SELECT can be handled several ways, but it still comes down to global locking of some kind. Another method is to use a stack file, instead of a directory. Since there's no need to close the pick file pointer, the overhead of opening(refreshing) and closing a local directory is eliminated. The only problem here, is the fact that every phantom has to lock the file before it checks any kind of stack status. That's not a problem on the MV side, but it can cause general service issues. If the MV file locks aren't file system(flocks/perms) as well, then the spooler could easily corrupt the stack with phantoms polling it constantly. Then, you end up having to write a stack manager to deal with I/O. Yes, all of that would work much better than directory polling. It's a lot more design work and can tend to be debugging unfriendly. Another method, which was implemented in a prior release of MVWWW, was through the use of O/S TCL command tools. Instead of spooling the request, the request was posted directly to the HTTP service via command-line TCL. The biggest drawbacks there were session init lag and overall insecurity. Anyone could telnet to the local Inet service and hack into Pick through the HTTP service. Starting and stopping sessions ended up creating a lot of load under D3, since it's VME based. It could be that this is the answer for UV, UD, and possibly mvBase. My only concern would be the user permissions required to make something like this happen in UV. I could be wrong though, I'm still a UV newbie. Finally, there was the gateway/manager I wrote in C and the stand-alone MV TCP/IP listener. The gateway maintained a list of available IP ports and provided a transparent TCP/IP bridge for the CGI client, into Pick. The only problem there was the use of a shared segment to store the port map. I actually ported it to Win32. And it ran like doo-doo. After about 10 hits per second, the Linux port handler went bonkers and stuff stopped working. The Win32 threaded version never left Alpha, before I dropped it in the shredder. I have to say, this was the speediest Linux solution by far. Response time was sub-second, provided the web app didn't take too long.

RE: [U2] Universe to Web interface
Kevin, I read through the PDF. However, it is not clear on how the handles can be used. A lot of the API's I've seen have the same level of functionality, but they all lack the ability to pass handles from the acceptor process to a totally separate user process. This isn't really an issue of the API, it's more of a user environment issue. You can pass the handle value itself, but the other process loses the 'meaning' of the handle and it just becomes a worthless string. An example would be launching a new phantom and passing it the handle variable, after accepting an incoming connection. The same situation occurs when you pass any kind of memory reference(or offset) to anything outside the current user heap. Unix fork()ing generates a mapped/duplicate user heap, so all file/handle references still work properly without having to munge underlying memory addresses. If you can truly pass a UV socket handle to another UV process, then there's no reason why anyone can't write a stable multi-threaded socket server directly in UV BASIC. Is this true? If so, I want a developer copy so I can try to blow it up. :P eg -Glen -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Kevin P Lynch Sent: Wednesday, February 09, 2005 3:52 PM To: u2-users@listserver.u2ug.org Subject: RE: [U2] Universe to Web interface you manage the connections from basic, the whole interface is a set of basic extensions. basically you open a socket on a port , accept a connection on that socket and write to the socket. here is the appropriate manual : http://publibfi.boulder.ibm.com/epubs/pdf/25119080.pdf -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Glen B Sent: Wednesday, February 09, 2005 2:31 PM To: u2-users@listserver.u2ug.org Subject: RE: [U2] Universe to Web interface Must be nice.

RE: [U2] Universe to Web interface
There are many ways to accomplish that. I've been crunching the methods for years and finally picked a simple, but flexible architecture. The main thing to consider is execution permissions. You don't want just anyone being able to run anything on your UV box from a web server or console. Take a look at the guts of MVWWW if you want a starting point to build your own UV http service. If you do, PLEASE let me know so I can include it in the project! This is a file-spool based http service. For Windows, you will need ActivePerl in order to run the perl spooler and CGI client. You will also need Winetd or another Inet variant for Windows. If you just want the architecture, then here's a compressed version. Client-side (browser) calls a URL. (http://www.myhost.com/cgi-bin/mvwww.cgi?mvwrun=testapp) The web browser executes the CGI script (mvwww.cgi in this example) The CGI script makes a socket connection to the spooler (inetd service the standard I/O app called mvwspool.pl) The spooler generates a unique ID for the request. The spooler grabs the query, post, headers, etc from the CGI environment and saves them to a request queue file using the ID. The spooler broadcasts the presence of a new queue item, by writing an empty file in the main spool dir using the ID. At this point, the spooler waits for a response in a separate response directory. Server-side, our HTTP phantom runs and waits until new item IDs show up in a local directory (the main spooler dir) NOTE: Just like using a 'critical section' in threading, the directory is locked via MV file lock when it is being read or written to. This syncs all phantoms and allows for multi-threaded processing. When a new item ID is found, the empty item is deleted from the main spooler directory so other processes won't barge in and take over our request. The HTTP phantom then reads the actual request from the request queue, using the item ID as reference. The request is parsed, looking for a static CGI variable. In the case of MVWWW, it's mvwrun. The subroutine to be called, is assigned to this CGI variable. We use CALL @ to call the subroutine named in the MV variable. Once our MV subroutine has RETURNed, we write the response into the response directory. The spooler sees the response, picks it up, and then sends it back to the client via standard I/O. That's it, in a nutshell. Plans are in the works to implement a spool manager. As it is, this architecture is not DoS attack proof. It also needs to have injection management added. As it is, you can inject a request directly into the spooler. The future manager will monitor how many, and how often, requests come from a client. It will also determine who can access it.

RE: [U2] Universe to Web interface
Not continuous, but the directory is polled. The only other sensible way around this is to use IPC or pipes, which is not portable. open the dir, select, and then readnext to see if there's a file item present. If so, delete it and process the request based on that ID. You're basically popping off the 'stack'. If your configuration isn't saturated, polling ( or stack poppin) takes a split-second to happen. It's not like there's 5000 items in the directory and you have to deal with select lag. I had one issue on OpenQM/Linux, with the select polling. A 'loosey-goosey' loop ate up all the CPU ticks. A half-second NAP or SLEEP solves the CPU problem, but it does reduce response time a tad. Adding another phantom will more than make up for that lag. Sure, there are a zillion other ways to manage a queue stack. This is the most platform and flavor cross-compatible. If you have another design suggestion that would work better, please let me know.

RE: [U2] EDI anyone?
Most of the Aerospace and government agencies we deal with regularly are using web portals now for procurement and supply chain management. EDI/VAN is disappearing, as more large companies put their funds together to get out of their EDI sink holes. The costs of VANs, and operating an EDI infrastructure now, are a lot higher than before. That's mostly because so many people are moving off VANs, in favor of e-mail or web based EDI-friendly gateways. The portals are many times more intuitive and organized than EDI could ever be. In many cases, the move to web portals means less employee requirements and therefore layoffs. That is good or bad, depending on which side of the fence your sitting. However; EDI conversations are still in use, but the methods of the past are disappearing. We've looked into hooking up with EDI, but most of our large customers still use Sterling Commerce as their VAN. We don't have enough margin to pay Sterling, even with the small byte transmissions we'd probably be using. So, we do more business(and can offer better prices in general) to those who participate in a non-EDI required setting.

RE: [U2] spammed
All it takes is for a bot to sign up for the list and begin harvesting. Without any decent bot-stops in place, everyone on the list is on a harvester buffet bar. If the only authorization required, is a 'reply' to the authorization response, then most harvesters can join without anyone realizing it. That is why our(All-Spec) commercial mailing list registration requires you to read an authorization code from the response e-mail and type it into a web form. Then, a human has to interpret a skewed/pixilated GIF and type in the visualized code into a separate web form. That stops most harvesters.

RE: [U2] [UV] Processing a string
You're right about url encoding and forms. However, binary transmissions have nothing to with HTML or XML. Binary has to be transmitted via HTTP under specific MIME headers, so the web server/application won't try to parse it as text. My rule of thumb is, don't stick protected characters in text content, unless you're SURE it won't get parsed incorrectly. A sure bet that it won't get messed up, is inside a TEXTAREA block for example. Sure, you can use and anywhere you want, provided you don't break the cardinal rules. Try this on for size: HTML blah/ /HTML Then try: HTML blah / /HTML and finally: HTML lt;blah/gt; /HTML According to what I've been reading, all 3 of the above should display the string blah\. However, option 1 breaks the rules by not having white space or ! after to identify that it's not an HTML element. Since there is a / before the , the parser thinks it's a self-closing tag. In this case, you will have to encode the string with either hex values or representations. On a side note, my XML subroutine will only extract tags and content between matching pairs. will be included in any wrapping elements, unless there is a matching /. Self-closing tags are handled differently, due to their syntax difference. Is it 100% fool proof? No, it's not a commercially developed application. It does a good job though. TAG/TAG will return as the element content for TAG. TAG//TAG will return TAG as null and delete the tag pair. TAG value=1/ wil return TAG = 1.

*bowing to the all-seeing moderator* Just a reminder, a 'maxlength = bytes' string can be set in each list config. Or, are you already getting too many bounces b/c of that?

RE: [U2] Avoiding automatic e.mails to the list
You can configure major donut to drop out-of-office bounces. You need to look into the majordomo.cf file for $global_taboo_headers = 'END'; There should be a list, under that, of bad subjects to bounce mail for. Add lines like this: /^subject:\s.*\bout of the office\b/i /^subject:\s.*\bout-of-the-office\b/i or (for vacations) /^subject:\s.*\bam on vacation\b/i /^subject:\s.*\baway on vacation\b/i You can tweak the conf file as you see new ones making through. Those four will handle most of the auto-replies from Outcast.

RE: [U2] Anyone have experience mirroring a HDD over a WAN
You can do that with rsync on *nix. Only the changed bits of files are transferred. There are other remote sync tools, just do a google for it. I wouldn't rely on the sync'd data, except as a 'last-resort backup', if the local copy folds up completely. It's not a good idea to try and keep a remote instantly live. The local copy can be rebuilt from off-site sources very quickly, using the same tools. For local hot-swap action and redundancy, refer to your neighborhood SATA or SCSI RAID vendor. 1 is the cheapest solution, while 10 is the best for overall error proofing and reliability. Also, 10 spans across multiple spindles before mirroring, so your throughput can be decreased significantly from that of a RAID-1 setup. http://graphics.adaptec.com/pdfs/ACSP_RAID_Ch4.pdf Glen http://picksource.com -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Dennis Bartlett Sent: Thursday, September 02, 2004 9:20 AM To: [EMAIL PROTECTED] Subject: [U2] Anyone have experience mirroring a HDD over a WAN Anyone have experience mirroring a HDD over a WAN? We have a scenario where triggers were going to be the data collection and a distribution program to blow extracted data to various end of the earth. All this was an attempt to maintain a 24/7 access to a working system. = All log on to the main server and work as at present. = When comms break at any branch, they log into their own server and continue to work (the data being an exact copy of that on the HO server up until the night before = synchronization to take place at night, when network traffic is lowest) We've now had to abandon triggers, moving to a scenario where we get to modify source code (not a preferred route). This has caused us to stop and think... if this can go wrong, how much more the distribution of data onto every server at every branch (20 branches, plus HO).

RE: [U2] Senior Pick Programmer position Denver, Colorado
I think codingitis is the cause. Time to lay off the keyboard for a while, man. You know, semi-colons start to disappear after 6 hours of continuous coding. Any higher amount of time can cause strange things to happen. I remember starting during mid-day and missing night-time once, while programming a test application in Borland C 3.0. I think my brain crashed and rebooted to idle, for the rest of the day. Though, I can't really remember much about that day.. or the application for that matter. *pondering look* I do remember that there was one compiling error that never went away.

RE: [U2] [UV] Anti-virus recommendations for Universe on Windows?
I'd prefer the entire file to be scanned every time. You never know if a virus is slowly plugging its bits into a file. A diff check on a file will not detect a known virus signature. The signature would be spread all over the file. Look at the B1 virus. It destroys FAT partitions by taking its time and deleting a link here and there. Nothing major to start with, until your files start to blow up one by one. :P A well programmed scanner with heuristic analysis can blaze through a 200MB file. Most virus scanners is a harsh term, considering I've seen 100-200%+ performance difference in scanning with 3 or 4 different scanners checking the same files. Every virus scanner has a focal point. Some focus on run-time checking, while another may focus on batch scanning or protocol sniffing. I've yet to find one that does it all extremely well and doesn't interfere with performance on a regular basis. F-PROT is about the best, overall, for all platforms. AVG is a great well-rounded tool for Windows. Panda isn't bad, but I still feel it's over marketed for what's really there. I remember them badgering me @ Comdex `99, every time I walked by their booth. Maybe I'm biased now? Sophos is OK, but it's popular enough to be a direct virus target. Does Sophos have integrity measures, to assure its own files can't be changed? I don't know how many times I've had to re-install Norton AV due to direct infection. I'm sure there are some other scanners that I haven't road-tested. For the most part, I'm happy with AVG on Windows and don't wanna look any further at the moment. If I was running X-windows, I'd have F-PROT running. After all, it was one of the first scanners and they have it down to a science now. I had the free version running on DOS 6.22 for my BBS back in the early 90's. Scary eh?

That's the problem with most virus scanners. Consider a 200mb file with a million records in it. What do you think the virus scanner is going to do each time a record (even one character) is changed in that file? Some of them must be intelligent enough to only access the parts of the file that have changed, such as the higher level backup programs do now.

RE: [U2] Precision question...
The main advantage of not storing the decimal, is being able to easily display a precision value any way you want. We do this (4-digit precision) for sale price calculations(cost * markup). The only drawback is making sure you keep all the values, for a specific record, in the same decimal length. On the other hand, you could store the masking length for each value, in a relative sub-value. I dunno why you'd wanna do that, though. MD (Decimal Mask) or MD (Decimal Output) (Decimal Mask) A=1.01643452 B=ICONV(A,MD8) ; 101643452 C=OCONV(B,MD28); 1.02 D=OCONV(B,MD48); 1.0165 E=OCONV(B,MD68); 1.016436 F=OCONV(B,MD8); 1.0164352 Forgive me if my rounding logic is incorrect. I can't remember if MD rounds up, if the next digit is not zero. Maybe some more caffeine would help.

Check out AVG. It's fairly inexpensive and it runs well on Win2K and up. Norton hinders more than it helps. I remove all copies of the NAV stuff from OEM PCs. I've never had anything but problems from it. Grisoft uses Inktomi for their updates, so upgrades and updates are typically fast. Plus, it's not a famous virus scanner, so trojans and bugs won't look for scanner files to mask.
