Re: Batch loop in SYSplex
Okay, This shouldn't be too difficult to determine. first, when you notice the HIGH CPU, what other address spaces are also showing HIGH CPU, there will probably be at least one. second, can you check your RMF III reports and see if there are any enqueues at the time, and who they are for I would be most intrested in contention for SYSZIGW3 IGWSHC02 resources if they exist (if so I have your answer). third, Have you discovered what actual programs are involved at the time, is this a standard IDCAMS job or is it a user written program of some sort that is performing the functions. I'm not sure about your expertise level, but the next step (if nothing came out of the above questions) would be a GTF trace so that we can see what we are doing.

Re: Matching records
I've read other replies to your email and agree with them. I have no idea where you are in the world, so I don't know what local resources you may have available. Here in the U.S., I'd suggest a community college for a beginner because they generally cost less. I don't know your financial resources, but a beginner really needs one on one teaching and mentoring for a while. If you work for a company which will allow you to write your own programs, perhaps one of the programmers there wouldn't mind doing some teaching on a part time basis. They might even change a reasonable rate. There is no such thing as a free lunch.. The problem with finding a web or email based discussion group for learning is that the members will likely range from techie god to can't tie their own shoes and you can't always tell who is who. This forum is not a good place for this sort of thing. Mainly it is a techie haven for more advanced questions. And you will likely eventually be ignored by most people here. And it is generally not really programming oriented, but software support oriented. Now, if you still intend to go it alone, I'd strongly suggest running a PC with Linux. Why Linux? Because it costs no money. You can download it freely. And there are many production quality software systems available for it. For an IDE, you can't beat Eclipse (free). For a database, MySQL is popular, but in my opinion, PostgreSQL is production quality. And both of these are free. Programming languages? My word! GCC (C/C++/Ada/Fortran), OpenCOBOL, Java, Python, Ruby, Perl, and list goes on to exotics such as Erlang. And the compilers are all no cost. The main confusiopn about Linux is which distribution?. I use Fedora (RedHat). Many use OpenSUSE (Novell). One of the major players for users is Ubuntu. Any of those three will be solid. Ubuntu may be easier for a new users because it is more friendly. Also, if you go Linux, you might find some of the help you need with a local Linux User's Group. Again, I don't know because I don't know where you live. And, lastly, I'm not a good teacher because I'm not a real programmer. I've never written a line of production code in my life. I'm a z/OS sysprog. I do write code. But it is more ad-hoc reports in REXX. Oh, I am familiar with a lot of languages.

An eventual (actual not possible for non-English users of the word eventual) response expanded the discussion, now essentially about automation, to the subject of closing down as well as starting up and hence a separate spotlight focussed on CANCEL etc. If you had been following all of this discussion you would have see that I am more than fully aware of program properties being set in the IEFSDPPT module and the SCHEDxx member not least because I think I have been returning to this topic from time to time since I think the late '70s when I very vaguely remember having to add entries to the IEFSDPPT module in order to cater for IMS. Can anyone confirm? Specifically - as I pointed out in my previous post - I responded to John McKown on 29 September with a post pointing out that attributes can be set in both the IEFSDPPT module and the SCHEDxx member with the later taking precedence. In other words that the sequence is - not unlike the logic for VTAM start options: 1. Assign default attribute values to the control block representing the address space for a particular program X 2. If there is an entry for the program X in the IEFSDPPT module, override the default values in the control block with whatever the bits in the IEFSDPPT entry specify 3. If the is a PPT statement for the program X in the applicable SCHEDxx member, override the values in the control block with whatever the parameters in the PPT statement specify Incidentally this control block is postulated for the purposes of explaining the topic - as a teacher might use it. The control block is not required to exist precisely as described above. I am now obliged to point out that some of these attributes will survive during the execution of the program in the address space *only* as long as they are not modified dynamically - as you pointed out. The archaic IEFSDPPT module is still valid, but for all practical purposes it is unusable. Unusable for all except IBM would be more accurate - although implied by your emphasis on vendors. As far as I can tell from scanning the section in the description of the SCHEDxx member in the Initialization and Tuning Reference manual, IBM routinely specifies its real or imagined requirements in PPT entries in the IEFSDPPT module. That tends to challenge your use of the adjective archaic. For example, there are revision bars in the current Table 23, IBM-supplied Program Properties Table (PPT) Values: http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IEA2E2B0/75.7 So your idea of having automation examine the PPT would likely yield no useful information for managing individual address spaces. I don't believe what I wrote suggested that *automation* should be involved in examining the IEFSDPPT module and SCHEDxx member. This is a task for the person setting up the logic driving whatever automation function is being used. For example my experience with automation was to start with a COMMNDxx member and submit commands from jobs where the jobs contain a step with a mickey-mouse program which executes an STIMER WAIT with a value specified in the PARM field of the EXEC statement as clobbered together in order to run an MVS system for an exhibition in the early '80s.[1] Later, for my test/education systems, when NetView provided a message recognition capability, my automation could become comprehensive and efficient. In none of these endeavours did I ever contemplate dynamic scanning of SYS1.PARMLIB members in order to direct my automation. It was all based on very extensive testing - as I expect professional automation inevitably will be. So your idea of having automation examine the PPT would likely yield no useful information for managing individual address spaces. I guess I - in my turn - could be all sorts of offended that you should ascribe such a ridiculous idea!!! The more fundamental question of what it really means to manage those address spaces is a can of worms I will leave unopened. You don't have to bother. The original thread did just that! I meant that there is usually a sound technical reason why the address space needs to be that way and you probably ought not assume otherwise. On the contrary, when it comes to an IBM product - and my particular experience is that the same applies to non-IBM[2] - do not trust anybody! In

Re: Defining more than 8 IP addresses in OAT
Gadi I've provided this comment to your original post in the IBMTCP-L list. It's copied here in case there are any interested here who do not also subscribe to the IBMTCP-L list. quote Gadi In principle you should be able to get your answer to this question in the following manual: Open Systems Adapter-Express Customer's Guide and Reference http://www-01.ibm.com/support/docview.wss? uid=isg2bc4ae2e43bfcf12c85256cee000d1130 It's worth referring to the manual since the folk responsible for the online bookshelves have taken it into their heads that no longer should there be a reference to this manual in the z/OS V1R12 OSA/SF bookshelf - OSA/SF always being rather an odd way to encompass the set of OSA manuals. This is a shame since if, in desperation, you go back a release from V1R12 to V1R11, you also go back a level in the manual - to say nothing about the bookshelf not having been updated since V1R10 - so I won't! However I tried to find where in the manual it actually said there was a limit of 8 IP address entries when using channel type OSE - and I failed! You might like to use the reader's comment form (RCF) technique - use the online references on the Edition page near the front - in order to complain that there is no description of a limit to the number of entries in the places one might expect to find such a limit mentioned: I was now going to list the two places I might expect to find the 8 limitation, in the description of the OAT Definition Line for TCP/IP and in the section where the functional limits are enumerated, but I noticed something very interesting - and absolutely not documented!!![1] You can certainly ask in an RCF what the Net_mask token following the Home_IP token might happen all to be about! I could guess that, in some sort of principle, it could be the answer to your question. What if the specification of a Home_IP address value *masked* by a Net_mask value permits the specification of a *range* of addresses? Intriguing, n'est-ce pas? Looking at your OAT, perhaps 10.203.10.0 255.255.255.0 would cover your 10.203.10.71, 10.203.10.91, 10.203.10.92 and many more adjacent addresses. Note that scanning the PDF of the manual for the characters Net_mask reveals this as the only occurrence.

However that isn't terribly flexible or useful for anyone else, so I stand by the term archaic. I hope you took the time to appreciate my description of how the Communications Server (CS) IP component developers and authors had got their undergarments in a twist over NOCANCEL in the case of the TN3270E server. I don't know much about Communications Server in particular, but I do know a little bit about z/OS internals and systems management products in general. I can't comment about whether the CS components really need to run with NOCANCEL. I *can* comment on the technical reasons why a server address space might need to run that way. I don't know whether the TN3270E server has those attributes or not. Do you? Or more directly, do you know for sure that they don't? And does it really matter? It is not very common to make address spaces non-cancelable and the reasons for doing so are usually technically deep. ... or maybe the reasons are accidental becausesnip I can't speak for all software developers but I can tell you that those big-gun decisions are never made by accident. At least not by the major software vendors. There are too many folks looking over your shoulder and second guessing everything you do. Not unlike ibm-main in that respect :-) Again we have developer arrogance in not leaving it up to the user as to whether or not to allow the user to advise his/her operators over cancelling the address space by allowing CANCEL or NOCANCEL to be specified by means of the SCHEDxx member with a proper explanation of the advantages and disadvantages, including how they relate to the use of the AUTOLOG facility. We're just going to have to disagree over this. Giving users a choice between things they don't really understand isn't really being helpful to them. Even if the choice is elaborately documented you've added something extra that must be read and understood and actioned and most users don't read everything we give them as it is. If making that choice is of no consequence and it only adds a small amount of work for the user then ok I guess. But if making the wrong choice can lead to a system outage (or worse) why would you want to have the user make that choice? I would prefer that the software should do the right thing for me. You may consider it arrogant and that's fine with me. I have more than enough scars already. Note that the main CS IP address is one thing and, who knows? - well I don't but, of course, the developers do - it may well be that the tricks the main CS IP address space gets up to are the same or similar to those you described in your concrete example. Perhaps so and as you say, you don't know. Nor do I. BTW The tricks I was referring too aren't especially tricky. The garden variety things that server address spaces tend to do are likely to result in dependencies between the server space and its clients. If you blow away the server you're very likely to leave the clients in a damaged state. If it is necessary to allow for restart and recovery for such a server space, then the clean way is for the server to accept a STOP command. Upon receipt of that command the server's internal tasks are all still running normally and they can go on about the business of shutting down gracefully. If you use CANCEL or FORCE that's no longer possible. All of the server's tasks are summarily abended and all subsequent resource cleanup has to be co-ordinated through end of task and/or end of memory routines. Trust me when I tell you that accomplishing that is enormously more complex and risky. An impatient operator with an itchy trigger finger can ruin your whole day. If I'm responsible for providing that functionality then minimizing the risk of disaster seems to me not to be the arrogant thing to do, but rather the prudent thing to do. Why are we even debating this? I can imagine that there are a number of functions the main CS IP address space could perform which imply NOCANCEL is a good idea. However the TN3270E server is just a TCP application with potentially - not necessarily - a mass of definitions to process on starting. It was the time which some customer definition sets needed to get up and running that prompted the separation of the TN3270 sever application - as it should have

John:I was watching this thread and I never thought about it to much so this morning while I was have a coffee I came up with some reason why z/os probably will not ever support cheap DASD. As far as I know there isn't an y decent builtin hardware error checking. In the MVS world it is just not good enough to say oops like it is the pc world. Companies spend the big bucks just for data accuracy and availability, they also spend money for thruput. I/O is always a bottleneck and the drives just cannot sustain the I/O that IBM (and some other OEM) manufactures supply. One of the side issues of a big drive is that it is hard to walk out the door with it. With PC drives that can be accomp[lished and no one would be the wiser. Again the PC people are generally not to interested in Security (we all know that security in an MS world is an oxymoron). Maybe in a high security environment they can stop such an event but in the common business world I do not think so. A side issue is that if an error occurs I have to suspect that each drive manufacturer handles it differently. In a MF world that can't be allowed to happen. There are only just so many possibilities that IBM could handle. Myself I would never trust the PC world to supply code to MVS to handle errors. Can we all say security breach together. There has to be other reasons but I think I touched the tip of the ice berg. Others should pipe up.

Re: CANCEL/FORCE ARM (Was: Really dumb IPL question)
Chris IBM does continue to use IEFSDPPT for some things that only take effect at IPL time. However that isn't terribly flexible or useful for anyone else, so I stand by the term archaic. We may have to leave our readers to decide whether something which stands a strong risk of being changed with each release of z/OS is archaic or not. I don't know much about Communications Server in particular, ... This could be the source of a lot of misunderstanding. I will try to compensate for this deficiency where necessary. ... but I do know a little bit about z/OS internals and systems management products in general. It's at the heart of my irritation in having NOCANCEL imposed that the Communications Server (CS) IP component has its own generally effective quite simple - some may say simplistic - bit of systems management support. I can't comment about whether the CS components really need to run with NOCANCEL. We - at least I - am discussing a particular CS component, the actually misnamed TN32760E server program, misnamed because it also supports raw TELNET as well as 3270 TELNET. I *can* comment on the technical reasons why a server address space might need to run that way. And your comments are well received. I don't know whether the TN3270E server has those attributes or not. The TN3270E server acts as a cross-over point for a TCP connection - acting as a listening server - to an SNA session - acting as a secondary logical unit (LU). When supporting an appearance as a 3270 device to an application such as CICS or TSO using the VTAM API the data supported throughout is the 3270 data stream. This is a quite simple task to perform and these days - in sharp contrast to its early days - is supported by parameters controlling every last aspect of the operation of this cross-over point. There are only two APIs involved: the VTAM API is very straightforward and the TCP API is very straightforward. There are no references to other address spaces.[1] I am not aware of any parameters which indicate that anything very special is happening which could suggest any special use of MVS interfaces. For example, CICS requires a particular VTAM specification, SRBEXIT=YES, on the APPL statement which indicates striving for a performance advantage. It can't be guaranteed, but I would expect any striving for performance advantages by employing - let us call them - the more advanced MVS facilities could very well show up somewhere in the definitions for the TN3270E server. On balance, I deem it most unlikely that anything is to be found in the now separated TN3270E program logic other than straightforward use of the two APIs. Do you? Questioned address already if not definitively answered. I think I'll see if I can't get it answered through some contacts I still have - and maybe the IBMTCP-L list - somewhat along the lines of What MVS facilities does the TN3270E server use which could justify NOCANCEL? - and hope the developers don't see or hear the blade falling! Or more directly, do you know for sure that they don't? As above. And does it really matter? Oh yes it most certainly does - or I wouldn't be spending anything like so much time discussing it and taking up so much or your valuable time as well - and that of and those still following with baited breath. This is where being familiar with the CS IP component is rather important. It's all in this paragraph from my earlier post: ... The requirement they did *not* consider sensibly was the NOCANCEL attribute. For those customers with the sore fists it indeed made sense not to include the program for the newly liberated TELNET address space in the AUTOLOG list - an action usually undertaken for any server program since the beginning of recorded time - but what about the less vocal majority? We are not talking about operators entering a CANCEL command here - as if they dare! We are talking about the AUTOLOG function in the CS IP component which is a crude but effective subsystem management function there to try to guarantee that a server program address space is always running to handle clients. The CS IP component checks that the TCP listen port is working. If it is not, there being no provision for individual instruction over how to shut down the server program in an address space - a deficiency you may say and I may even agree with you - a CANCEL command is used. This AUTOLOG function operates only when the name of the server started task procedure is present in the AUTOLOG statement list. Normally a customer will put any server started task procedure name in this list where the nature of the program, a server according to the traditional client-server model, is to take a client's request, get on with it and end the transaction. If the server is not listening on the TCP port which the clients use to initiate a transaction, it is a waste of (address) space! As such it needs to be

Re: When will MVS be able to use cheap dasd
Ed, In case you didn't know, the SAS and SATA drives in an enterprise Array that supports directly attached CKD volumes are the same as the SAS and SATA drives in Midrange storage. You also must have missed the fact that Hitachi have been supporting Mainframe volumes on Midrange storage for over a half a decade. This uses Virtualization through the DASD Controller to encapsulate CKD storage onto FBA storage, just like the internal drives. The difference between the cost of midrange and enterprise storage has little to do with end-to-end data protection, because it's all SCSI, SAS and SATA once your write leaves the FICON channel on Enterprise. It has much more to do with survivability, availability, scalability, and software options or lack thereof on midrange storage The best illustration of this were the last set of ratings that the now defunct RAID Advisory Board issued, where most Enterprise Class controllers were classified as Disaster Tolerant Disk Subsystems, and midrange was typically classified as Fault Tolerant Disk Subsystems. Typically midrange storage will stay connected and keep running if a component fails, but FRU replacements, upgrades and suchlike are likely to be disruptive - they're not five nines in all situations and that's why they are cheaper.

John:I was watching this thread and I never thought about it to much so this morning while I was have a coffee I came up with some reason why z/os probably will not ever support cheap DASD. As far as I know there isn't an y decent builtin hardware error checking. In the MVS world it is just not good enough to say oops like it is the pc world. Companies spend the big bucks just for data accuracy and availability, they also spend money for thruput. I/O is always a bottleneck and the drives just cannot sustain the I/O that IBM (and some other OEM) manufactures supply. One of the side issues of a big drive is that it is hard to walk out the door with it. With PC drives that can be accomp[lished and no one would be the wiser. Again the PC people are generally not to interested in Security (we all know that security in an MS world is an oxymoron). Maybe in a high security environment they can stop such an event but in the common business world I do not think so. A side issue is that if an error occurs I have to suspect that each drive manufacturer handles it differently. In a MF world that can't be allowed to happen. There are only just so many possibilities that IBM could handle. Myself I would never trust the PC world to supply code to MVS to handle errors. Can we all say security breach together. There has to be other reasons but I think I touched the tip of the ice berg. Others should pipe up.

Re: When will MVS be able to use cheap dasd
While we will of course work with anyone to get them going if necessary, and although we do have this capability to a very limited degree today, the DVD support for the Customized Offerings Driver that will make this function available to everyone is not planned to be generally available until 1Q11. Thanks, John. Sorry I was a little over-enthusiastic. Anyway, yes, IBM is planning general support for loading z/OS from scratch from DVD (sans tape) onto an empty mainframe. And yes, this capability would often be useful for both new and current z/OS customers. This support was announced in July with z/OS 1.12 and has a planned availability date of February 22, 2011 (Customized Offerings Driver on DVD). OK, so it's not entirely clear in the announcement letter what that support means in practical terms (DVD bootstrapping of z/OS), but that's what it means. :-) Plans can sometimes change, but that's the plan. As for speed, that'll no doubt be situational. But, to give some idea, you'll be loading the Customized Offerings Driver which is rather small (by today's standards anyway) and reading it from DVD to get going. (That's reading, not writing.)

Re: Two HSM's on one Lpar
Mike, If your customer is using Hitachi DASD Controllers than perhaps you can bypass DFSMShsm altogether for these datasets and used virtualized midrange storage that was discussed in another thread. Using some brand of modular storage with SATA drives - whatever's cheapest, it doesn't have to be from HDS - you can create a STORGRUP of 3390-54 out of volumes that are backed by this cheap storage. Then you can simply run a DFSMSdss job ever day against that HLQ to move datasets using the BY keyword to filter on MGMTCLAS and CREDT. You could also get fancy and use a DCOLLECT to build a FILTERLIST based on last reference date, but I'm sticking with the simple stuff. The STORGRUP would be remote copied in exactly the same way as the rest of your DASD, or you could choose to use HUR or XRC for this Storage Group, while running TrueCopy Synchronous for all the rest. It's a choice not a requirement and it meets the customer's need to get this data on cheaper storage, but have it available for Disaster Recovery. If you are also licensed for FlashCopy then I'd suggest running this every hour instead of daily to emulate Interval Migration to pick up old GDGs. All the other stuff normally handled by DFSMShsm, like Space Release and Expiry would continue just like normal because the datasets are Primary Volumes. Net-net you can deliver a solution that's probably cheaper than using DFSMShsm because you never have to do an IO to it. You can even choose to write some of the datasets to this STORGRUP from the get go and bypass all the DFSMShsm management. There's a bunch of other ways to do this even better with Hitachi Tiered Storage Manager on top of all this, but I'm just trying to offer a simple solution. If you don't have Hitachi DASD controllers than I guess you'll have to ask the vendor they're using if they have something similar. All of the big three offer internal SATA disks that could be used the same way with HUR, XRC or SRDF/Async.
