Re: [U2] Signature Capture and use
I'm guessing you are not running a .net GUI frontend application. We have signature pads connected to our telnet-based Universe system. (a) We use AccuTerm to fire an exe on the client PC. (b) The client exe is a .net program with manufacturer's dll's that communicate with the signature pad. (c) When the user OKs the signature, the client exe sends the signature bytes to the application server via sockets, then exits. We had tried to use network shares for (c) but they proved to be unreliable. In a future version, I want to create a client exe with a socket listener built-in and run it like a service. That way, the application server can use a socket connection directly with the exe (instead of firing off the exe via AccuTerm). Theoretically, such an exe could be used via javascript in a browser-based application too. rex On Thu, Jun 6, 2013 at 3:59 PM, Oaks, Harold harold.o...@clark.wa.gov wrote: I'm sure some of you are implementing signature pad capture to a Universe system.

Re: [U2] Detecting idle time in INPUT statement.
I know the OP wanted to know how long a user session has been idle, but real problem is the second person waiting for the lock to be released. The best practice is to always have LOCKED clauses on your READU's, and never to block on a lock, i.e. a user input process should hit the locked clause and report who has the desired record locked, and giving the user an out if they cannot access the record at this time. Batch and phantom processes should not block either, waiting 5-10 seconds and retrying up to specific number of times (say 10), then skipping over the record and leaving it for subsequent processing. rex ___ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
Re: [U2] Detecting idle time in INPUT statement.
It does not matter if a system is old or not, you gotta keep it up to date. Maintenance programming means adding LOCKED clauses that should have been there in the first place. I doubt it would take more than a few hours; probably less time than writing and debugging some off-the-wall input timer routine. There probably aren't that many critical READU's.

But typically protocols pass packets back and forth to establish the connection before sending the data, and if it is failing at this level wireshark may make it obvious. rex On Wed, Aug 3, 2011 at 6:27 PM, Michael Pflugfelder mpflugfel...@ratex.com wrote: Rex, How could I make Wireshark work with uvtelnetd.

Re: [U2] Using SSL, with .Net to make a connection to Linux/Unix
Michael, It may help to put a packet-sniffer (wireshark) on your network to see what packets are being exchanged when the vendor app attempts to connect to uvtelnetd. The requests/responses may help to determine the problem. It may also help to compare the traffic between the working (windows) and non-working (linux) connections. rex We are working with our vendor to replace a front-end application written in Delphi with a new front-end application written in .net. The vendor has decided to remove support for SSH and telnet completely. The only connection they will make is to a UniVerse server running uvtelnetd. The way I understand this, it is simply Telnet over SSL. They have this process working with a UniVerse server running on Windows. We are now trying to make it work with our UniVerse server running on linux and it will not connect. ___ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users

Re: [U2] Record Locks - How long should they last for? (Opinion)
Based on your description, you are using a pessimistic locking approach (similar to a telnet user) for a web application, so choosing a timeout would be arbitrary. Your heartbeat idea could be tied in to avoid having to manually release records. It seems like a bad idea to force a connectionless, stateless web browser to act like a connected, stateful telnet session. Why not switch to an optimistic locking approach? Checksum the original data (record) when it is passed to the browser. When returned from the browser, lock the record and checksum it again. If the checksums match proceed with the write; otherwise, send a message back to the browser allowing the user to cancel or resubmit their changes. This way, record locks should only last a few milliseconds. rex ___ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users

Re: [U2] Is this worth rewriting?
good comprehension = faster, accurate programming (that's programming, not code execution) We all want fast and accurate programming. To improve comprehension, you have to write code to (a) reveal its logical structure, and (b) reveal the business rules implemented in the code. Sorry, but structures like: IF A:B:C NE '' THEN CUM(M) = A+B+C (concatenating variables as a string, then performing numeric operations on them) slows down the comprehension process. And for what benefit? To me, that's just a lazy programmer that doesn't want to type a few extra keystrokes. Another structure caused a number of comments: IF condition THEN statement ELSE other-statement END (inline THEN followed by block ELSE). It appears that some readers saw the # in the condition and assumed an If Not Not structure at first, missing the THEN. I find it interesting that no one has commented on the fact that CUM(M) gets conditionally reinitialized, and whether or not that is important. But it proves my points that neither the structure nor business rules are clear within the OP's code. You can have 2 years programming experience, or 20, it does not matter. Better structure and variable naming will vastly improve program accuracy. (On the other hand, I could make this code really, really fast if it didn't have to be accurate!) rex ___ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users

Re: [U2] UI standards
As far as UI standards for data entry applications are concerned, I recommend Microsoft's User Experience Guidelines as a starting point. Google msdn windows 7 user experience guidelines, navigate to the MSDN page, find the PDF link and download the document. Most business people use Microsoft products daily. If your application follows the same basic layouts and uses the same keyboard shortcuts, your users will quickly learn your application; as a bonus, your application will teach them how to use their MS products. However, if your application works contrary to MS products, or requires them to memorize a different command set, then they'll despise you and your product. Have your developers read the book GUI Bloopers to avoid stupid GUI layouts. Also User Interface Design for Programmers is helpful. http://www.joelonsoftware.com/uibook/fog000249.html When is it okay to break out and show off a new interface? When it matches the user's imaginary model, not the developers!

I don't know of specific limitations concerning decimal places, but I do know that precision differences in floating point math cause unexpected behavior. If you're trying to total dollar amounts in a program, it's a best practice to ICONV them into integers before any math operations -- this eliminates all floating point problems.

Re: [U2] UV to SAP migration disaster
It's fun to think of UV as the underdog and how the cards are stacked against us. It's fun to be in the I told you so crowd when the competitor fails. But it doesn't matter if the competitor wins or loses; the reality is that another UV site has bit the dust. WE LOST -- that's my real concern. What didn't happen to prevent this conclusion? While it seems politically correct to point the finger at incompetent management, or ineffective vendor marketing, there's possibly another contributing factor, one that we as a group seem reluctant to talk about... the fact that we (U2 professionals) have dropped the ball. I can't help but think that if Shane Co. had a complete, cost-effective U2 application that supported all aspects of their business, there would have been no reason to move away from it to SAP. Management doesn't really care about pretty pixels nor usability. If that's what they're telling you, then they probably think they're doing you a favor by putting it in terms you can understand. Ladies and gentlemen, it's always about money. Being a group of experienced U2 business analysts, you'd think we'd know by now that it's always about (a) increasing revenue, (b) reducing expense, (c) bringing in more customers, (d) getting more business from the customers we have, and (e) reducing risk. Every discussion with management must be framed exclusively in these terms. Only then will management give you the right to contribute your opinion to a decision. As a side benefit, they will be wary of competitor salesmen that cannot articulate specific revenue and expense advantages. Hard dollar figures, i.e. money, speaks louder than marketing. You want to put a new GUI on that old application? Management won't stop you if you can prove it will make money or reduce support cost. But don't be fooled; some bulls**t cost analysis won't buy you any credibility with management. Don't expect management will do this analysis for you; if they could, they'd already be doing it. Back to prevention -- it takes a very deliberate and thoughtful cost-justification strategy to build up your existing U2 application.

Re: [U2] UV to SAP migration disaster
But it's always about the money. If the current UV system is perceived to be incomplete, management is FORCED to decide between buy or build -- both take money. And they will automatically lean towards the solution they are familiar with (just like we do.) As UV professionals, we need to address this human dynamic: Mr.NewGuy came from a place where he used Feature X. Your UV application doesn't have Feature X, so Mr.NewGuy sees the it as incomplete or lacking. Mr.NewGuy knows first-hand that this feature benefits the business (i.e. makes or saves money). Have too many of these missing features and Mr.NewGuy has no choice but to SPEND MONEY and replace the whole system. Real or not, Mr.NewGuy feels the pressure to do SOMETHING because he FEELS the old system is losing money. So how do we address this? Strategy 1: Don't fool yourself. Just because you have a working application in production doesn't mean it couldn't be significantly better. Strategy 2: Anticipate and implement useful features. Study your competitor's systems and stay informed of the latest solutions to business problems. Don't have Excel export capability? Get it. Don't have mobile applications? Get them. Strategy 3: Always make your managers look good. Mr.NewGuy has revenue and budget goals -- build an application that meets those goals. If Mr.NewGuy is meeting his business goals, there's no reason for him to tell the CEO or board to buy a new system. Strategy 4: Always have a higher ratio of revenue projects vs. infrastructure projects. Face the fact that GUI'izing you legacy application is an infrastructure project and will more than likely cost the company more than it gains. Balance infrastructure projects against a larger number of revenue projects, or perhaps even rolling infrastructure changes into your revenue projects. Stop doing those quick and dirty reports that everyone wants but don't generate any revenue or savings. Strategy 5: Sell your U2 application to management. YOU need to constantly market your product to management (but of course you really need to believe in it first). By product I mean both your U2 application and the services you provide to benefit the company. rex Jeff Schasny wrote: Unfortunately, its not always about the money.

Re: [U2] UV to SAP migration disaster
I guess the basic premise of your argument is that the PHB's are listening to 90-day-wonder windows programmers, and they encouraged said PHB's that they needed to replace the UV database. I don't buy it. Even PHB's don't go spending millions of dollars on SAP just because their 25 year old windows programmers don't think UV is productive. In the case of Shane Co. the PHB's decided to spend millions of dollars -- and no one bothered to do an ROI study? Or it was fabricated by a bunch of idiots without any concept of reality? At some point, Shane Co. must have been doing good. They were expanding. It seems a short time ago I heard they opened a new store here in Orlando, FL. (Or maybe they weren't doing that good after all and the expansion was a feeble attempt at opening new markets to generate revenue.) During this expansion, one of the PHB's must have said we AREN'T getting what we need from IT; let's look into other solutions. Or maybe they said, we CAN'T get what we need. (The former speaking to an unwillingness to address needs; the latter, lacking capability to do so.) And this brings me back to my original question: what was Shane Co.'s REAL reason for deciding to migrate away from UV? If Universe is supposed to be a superior environment for building and deploying business solutions, why couldn't their existing IT staff deliver? Why?

On windows, u2pipe uses wininetd; on unix or linux it can be used with either inetd or xinetd (with xinetd you can limit the number of simultaneous connections; pending requests get queued.) I'm not sure I understand your question, but wininetd/inetd/xinetd can listen on any port you specify, receiving raw requests from any system and sending back any kind of response data. So the requester (i.e. client) can be a browser, web server, or ANY other program that can interact with sockets. While you can write a socket listener in Universe basic, it can't be completely fault tolerant; the process can block or hang.

Re: [U2] [UV] PHP/Perl
Jeff, Charles, I basically used the same strategy when I wrote u2pipe, which is a C program that uses InterCall to connect with the U2 database. To add functionality, I add a Unibasic subroutine and a method in whatever web language -- right now ColdFusion and PHP, and looking to add ASP.NET soon. U2pipe relies on an external socket listener: xinetd for linux, inetd for AIX, and wininetd for Windows. The socket listener does not have to be on the same machine as U2 as long as it's reachable via the network. Using config files, multiple connections can be made (one socket port mapped to one U2 connection). I'm working on a connection pooling version, but it's not ready for prime time. The web server doesn't need to be on the same network. All of our deployments use a remote web hosting solution. So the web server is hosted in one state, while the actual U2 database is in another. The code and documentation is on www.PickWiki.com. Jeff Butera wrote: In a nutshell, I wrote a small C program which leverages Intercall to make connections to the database.

Depending on undocumented behavior is usually a bad idea. Just because A0 = 'ZZZ' happens to work in this release is no guarantee that the vendor will continue to support this behavior in the future. The fact this doesn't work in other Pick flavors or variants makes me want to shy away from this construct. rex --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
Re: [U2] What Next?
Al, Software development is inherently an exercise in climbing steep learning curves - an exercise in problem solving - and the learning curves don't disappear -- Steve McConnell I find that Steve's quote equally applies to professional development; growing as an application developer is a continuous exercise in climbing steep learning curves that don't disappear. So you want to stay in application development and support... reasonably employed. Here's my two cents: Learn to program in C. If you want to stay in the construction side of development, the aptitude to understand C is what separates the men from the boys. Notice that it's an aptitude; some people just don't have the brain cells that understand memory allocation, let alone pointers and recursion. Not everyone who calls themselves a programmer has this aptitude. Many productive Pick programmers fail to develop skills outside of Pick because the other languages don't make sense to them. If you can make sense of C, then a whole other world of programming languages opens up. Java, JavaScript, PHP, Perl, VC++, C# and all of the other so-called curly brace languages. I recommend getting the book Teach Yourself C in 21 Days from your library or bookstore. Remember: the reason for learning C is to provide a stable stepping stone to other similar languages. In this day and age, I'd recommend C# as your next language: Eric Sink referred to it as Java done right. Also on the construction side of development, get Mike Gunderloy's Coder to Developer to familiarize yourself with the different software tools available. Most Pick shops don't do daily builds and regression tests, and you'll want to see how the other half lives. If you don't know them already, you must learn XHTML, CSS, and JavaScript. Almost every modern product has some kind of web display or interaction, so there's no excuse to be ignorant of them. I see the biggest strike against Pick in general is it's perceived lack connectivity to other applications. It's not true, but it seems that way. Why? Because most Pickies are ignorant of how the big SQL apps work, plus unfamiliarity with UniObjects, BCI, and other connection techniques creates doubt -- a doubt that there's a simply easy way to move data back and forth between apps. So Mr. SQL says, convert that Pick database to SQL because it removes that doubt. To counter this perception, we need to be masters of connectivity. Become *fluent* in the technologies to connect U2 with the outside world. Construction and maintenance are maybe the most visible aspect of application development, but probably not the most important. Analysis and design are. To grow in these areas requires study, whether that's taking courses or reading books. Read all the Steve McConnell books you can find. Learn how to create function specs and system architecture designs. Learn about design patterns. Find out what MVC is. Learn accounting and business processes. The Accounting Game is a good book for newbies to get a grasp on both bookkeeping and general accounting concepts. Most other books focus exclusively on the concepts, which are easy enough to understand. The hard part of accounting is learning the specific accounts to debit/credit for a specific transaction; most of the time this is learned on the job. The Accounting Game does a better-than-average job teaching the transaction/account relationship. Last, consider getting a CS degree if you don't have one. I hesitate to recommend this, but I know most job postings list it as a requirement. I think it will pay off in the long run. I realize that this is a long list of stuff to learn. And the steep learning curves won't disappear. You need to ask yourself if this is the path you really, really want to take. rex --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
