Re: WLM for toddlers
OK, let's take this example of DB2 stored procedures. When you say controlled by WLM, what does that mean? How does that work? I read this DB2 Magazine QA article: http://www.db2mag.com/qanda/040817.shtml At the end of the article, the last paragraph states: When a program calls EAST.MANY_SCHEMA_PROC (for example), DB2 finds the corresponding row in the SYSROUTINES catalog table. It tells WLM to execute program SPLDMOD1 in application environment WLMENV1. Because the load library PRODLIB is in a STEPLIB in the JCL for WLM environment WLMENV1 (or in a JOBLIB or in the link list), the module SPLDMOD1 is found and executed. The package from EAST_COLL will be used (as specified in the CREATE PROCEDURE statement), and so tables qualified by EAST will be accessed because the qualifier EAST is used to qualify unqualified SQL statements in the program (also specified in the CREATE PROCEDURE statement). My initial questions are: 1. In this example, what is WLMENV1? Is it a constantly running address space that gets requests for work to be done via WLM? 2. Or is WLMENV1 a started task procedure or a JOB JCL member in some library? 3. How does WLM monitor/manage/control or communicate with this WLMENV1 application environment if WLMENV1 is something that executes independently of WLM? Remember, toddler's first steps. :) TIA, Jerry On Wed, 6 Feb 2008 10:17:26 -0600, Luis Miguel Martinez [EMAIL PROTECTED] wrote: If you want to testing DB2 stored procedures controlled by wlm ... you need the WLM environment customized in goal mode, DB2 customization, WLM application environment. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Re: Change DD SPACE-Allocation at runtime
As previous posters have noted, you can change the secondary by doing an OPEN-J and modifying the JFCB at execution time, but of course this would have to be done by the application opening the dataset. You can also change the secondary for an existing dataset by specifying it in the JCL but the question really was how to do this without changing the JCL. There is also, of course, no way to change the primary space specification outside of JCL, since allocation occurs before execution. Assigning a data class does not help, since data class attributes are overridden by attributes specified in the JCL. (The above is true unless, of course, you have a product such as Allocation Control Center or similar products which will allow you to enforce policies for primary, secondary, RLSE, dataset size etc., via a set of policy rules that are invoked prior to allocation).

My initial questions are: 1. In this example, what is WLMENV1? Is it a constantly running address space that gets requests for work to be done via WLM? It is the name of the application environment. That application environment gets defined in WLM. One of the definition parameters is the procedure name. The proc name may or may not be the same as the application environment name. The standard I set for our shop (after everyone started requesting their own names) was Wnnn where was the DB2 subsystem name and nnn was anything else (usually numeric). For example, DB2PW001. That allowed me to mask STC WLM rules by subsystem for the various application environments (DB2PWnnn vs DB2TWnnn service class). To answer is it constantly running: There are other definitions besides the proc name in WLM (see the fine manual for all of them). One those definitions tells WLM how many to start - 1 per system, 1 per sysplex, or WLM controlled (no limit). When work is queued for the application environment, WLM will look to see if there is one active. If not it will start one. For definitions that are controlled by WLM (no limit), WLM will start additional ASIDs (procs, servers, whatever) if it thinks that will help. In cases where there is only 1, I think WLM will stop the application environment after it is idle for 1 hour. If there are multiple ASIDs started idle ones are stopped more aggressively (after 5 or 10 minutes). The last one still must be idle for an hour before it is stopped. I'm not positive on the timings of the above... hopefully a DB2 person will correct me if wrong. 2. Or is WLMENV1 a started task procedure or a JOB JCL member in some library? It can be a JCL (PROC) member if the PROC name is defined as the same name as the appl env. See above. 3. How does WLM monitor/manage/control or communicate with this WLMENV1 application environment if WLMENV1 is something that executes independently of WLM? It doesn't execute independently of WLM. That is why it is called a WLM controlled application environment. :-) WLM monitors it the same way WLM monitors everything. Sampling.

Re: VSAM Surprise
PDSE's have a different directory format that allows for split directories the blocks of which are not always concurrent in the dataset. They are direct access. They also support functions not available on a PDS, such as Object Oriented modules, DLL Modules, etc... As such the direct access of the directories prevents writing unless through the correct service. Reading can still be done, but it only returns information in a format that emulates a PDS directory format. When I needed to alter a PDSE directory from a program I usually cheat, and have the program invoke directory services through REXX and ISPF functions. It can be done, but it just takes a different route. PDS directories have to be writable; otherwise you could not use TSO XMIT to pick up service packs packaged in PDS's for various products. This is one example of why a directory of a PDS is writable by design. There are plenty of other situations where this is used.

Re: WLM for toddlers
Jerry, A DB2 external stored procedure executes fenced that is to say, outside of the DB2 normal address spaces. To do this, DB2 utilizes WLM Application Environments. In the definition (in the DB2 catalog) for the SP is the name of the load module to execute, and the application environment. When the SP is called, DB2 and WLM will get an address space running (using the PROC named in the WLM AE definition). A task in this address space will then link to the named load module. So the stored procedure program, along with any modules needed will execute in this WLM AE started task address space.

I see there is a lot of speculation and incorrect statements, so let me try to clarify. First, from a processor implementation point of view, there is no problem with the old-style MVCL/CLCL interruptible instructions. At appropriate points based on pending interrupts and potential page crossings leading to an access exception, the millicode exits from their execution and sets the GRs and PSW appropriately to continue later. There is no risk of checkstops and it is perfectly well architected to handle a page fault in the middle, as some have speculated. The reason for the new CC3-style interruptible instructions is very simple. It was requested by software developers (both internal and external to IBM). It allows more flexibility in handling other system activity that is not interrupt driven. So for example, software can go off and perform some housekeeping while a long running MVCLE is executing. Note that POPS requires the processor to exit with a CC3 every (approximately) 4KB processed. So for a multi-page move, the overhead of starting and stopping can actually slow down the throughput of the move very slightly. I would expect that all future interruptible ops be of the CC3-style. That said, there will be at least one new interruptible version of an existing instruction announced soon, however, it is an instruction never used by the vast majority of software developers. re: http://www.garlic.com/~lynn/2008c.html#67 What happened to resumable instructions? long storage-to-storage operations with lots of accesses back to real storage ... is costing ever increasing number of processor cycles (as mismatch between processor speed and memory speed increases) ... recent reference http://www.garlic.com/~lynn/2008c.html#92 CPU time differences for the same job one could claim that nearly the same effective results (cc3-style) could be achieved for old-style interruptable instructions under program control ... but requiring a few more registers for loop control ... i.e. actual length is kept in other registers and the lengths used for mvcl/clcl instructions being limited (to 4096). there are other thruput issues associated with long storage-to-storage operations; even back to working on original mainframe tcp/ip product implementation. at the time, some of the competitive tcp/ip implementations were looking at 5k pathlength and five buffer copies ... and there was comparison with something like 150k instruction pathlength and 16 buffer copies for lu6.2. at that time, assuming 8kbyte NFS size buffer ... the processor overhead for the 16 (LU6.2) 8kbyte storage-to-storage buffer copy operations exceeded the processor time for the rest of the pathlength. the other factor that some processors provided was cache-bypass, storage-to-storage instructions.

My question is if there is a way to have the usermod replace the SAMP entry, assemble and link it, and replace the installed PROGRAM entry.

The problem is that if ++the vendor ships a new version of any of these two objects, the conflict will not be spotted by SMP/E who knows my alteration using different data element names.

Re: LOCAL LOCK and abend
Thank you for the pointer. I found the answer: Choosing an ESTAE-Type Recovery Routine Use ESTAE-type recovery routines to protect programs running under enabled, unlocked tasks (EUTs). ESTAE-type recovery routines can be in either problem state or supervisor state, and can have any PSW key. Programs that are disabled, hold locks, or are in SRB mode cannot use ESTAE-type recovery routines. If your program obtains a lock after you activate an ESTAE-type recovery routine, and then encounters an error causing your recovery routine to get control, the system releases the lock. You could use an ESTAE-type recovery routine in this situation if your program can tolerate losing its lock. For example, the lock might be used only to protect a queue from change while it is being read. and later, Locks: All locks are freed before the first ESTAE-type recovery routine gets control.

Re: WLM for toddlers
Ted, actually you are the one mixing the terminology. WLM application environments (AE's) are either available or quiesced. When an application (in the DB2 stored procedure/UDF case, DB2) requests a connection to an AE, if the AE is quiesced, the request is failed, if available, then WLM will determine if an address space is currently running with matching performance characteristics, and if the address space has an available task. If so, the work is passed to that address space. If the current address space does not have an available task, then WLM will look at the limits, and either start an additional address space, or put the caller in a wait until a task becomes available. If no address space is started, WLM will attempt to start one. Once started, the address spaces remain running for 60 minutes after the last request is completed. The note about matching performance characteristics is important, because WLM can start multiple address spaces, even if limited to one per system, because the 1 per system is really one per system per callers service class. If you have 4 service classes running DB2 work (TSO, DDF, CICS, BATCH etc), you could have 4 AE address spaces running. Also, the process of resuming (making available) or quiescing AE's is via a WLM VARY, not a MODIFY.

Re: CPU time differences for the same job
3. You can run the same job multiple times to see what the variability is for the particular job. Agreed, that seems to be the only sensible solution, though not an entirely satisfactory one. Why would this be unsatisfactory? On a z9 processor, 1.7 billion machine cycles (operations) can occur every second, for every engine. What makes you think that you can even remotely begin to describe what identical means for any given unit of work. The very nature of the interactions between programs practically requires variability rather than predictability. Even if you thought you could isolate each event, there are many that will be unknown (not disclosed in the architecture), subject to variation due to the last function performed, and unmeasurable. Why would you think that absolutely single measurement repeatability was possible? As I stated before, there will be variations, but it isn't random. Similarly in all my years, it is no coincidence that most operations departments were quite comfortable in knowing roughly how long any given job was expected to run (I know there are/were exceptions). The reason they knew this is because it was repeatable. The fact is that an identical unit of work will operate around a range of values and can be measured. Once measured, then the variation can be analyzed and a reasonable probability can be defined to account for the work unit's run time. If you want to know how a particular unit of work will be behave that you need to come up with a probability distribution function and run it repeatedly under controlled circumstances. This isn't simply some arbitrary point, it is absolutely required to be rigorous. This concern about applications is ill-conceived if it is thought that a one-time measurement should produce reliable results. If an improvement occurs, then the probability function will change and the results can be quantified. In truth, I suspect most of this work hasn't actually been done anywhere to either: 1. Define identical 2. Set up conditions to replicate as close to identical as possible the circumstances for a unit of work 3. Measure the variation under controlled repeatable circumstances. 4. Measure the variation under varying loads. (which negates identical).

I know some of ours are never started unless the DB2 folks do something to start them (like one that refreshes the environment). If defined in WKM as 1 per sysplex it won't start on all members. If your DB2 is single system in scope (even if in a sysplex) it will never do that. http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IEA2W171/13.4?SHELF=IEA2BK71DT=20070126163708CASE= I'm not a DB2 expert so I can't say too much more from the DB2 point of view.

Re: CPU time differences for the same job

They are not JES reported They appear in JESMSGLG, therefore they are JES reported. I don't particularly give a feghoot what program actually generated the message because it isn't relevant how the message was generated. The TCB/SRB time message appears in a JES output dataset so it is, in fact, JES reported. Picking a nit like this one is neither helpful nor germane to the discussion at hand. 2. Most of the variability should be in the SRB time. The bulk of the early posts in this thread were discussing TCB or both TCB and SRB time elongation due to the various factors cited. I would agree with you that in a normal environment, SRB time *should* be the most variable. What this thread has been about is that it *isn't* only SRB time that varies, and the environment *isn't* nearly as normal and predictable as we were taught to believe it was. 3. You can run the same job multiple times to see what the variability is for the particular job. Agreed, that seems to be the only sensible solution, though not an entirely satisfactory one. Those numbers and the Strobe product the only tools I have available to me. Strobe should be enough to find the hot spots. Not as easy as it looks. Sometimes the hottest spots aren't in your control (I/O subroutines for a data store owned by another application group are one such example). Priorities aren't always perfectly aligned in such cases. It's very discouraging to be told the tools you depend on are unreliable and unpredictably variable. Who told you that? The details and discussions in this whole thread told me that. The fact that two runs of the same work on the same system at similar times may vary by 10%-20% in CPU time is what I would call completely unreliable. 1%-2% can be called variable, but 10%-20% is a major difference that cannot be simply accounted for, except by throwing out low and high values from multiple runs as was suggested earlier in the thread.

Re: Clarification Needed for SMS exits - regd.
It's a good question. I don't think there's really any easy way to do this. The problem you have is that ISMF doesn't check when adding or removing volumes from storage groups whether the volume is empty, is initialized, or even if it exists. It has to do this since the configuration that's being updated may not even exist on this system but might be being built, for example, for another system altogether. Unfortunately, this means that if you remove a volume from a storage group, then activate the configuration, and then try to allocate a new, non-SMS dataset on that volume, you get an allocation error (diag code 04160055 - trying to allocate a non-SMS dataset on a volume in which the VTOC/VTOCIX indicate the volume is SMS-managed), although any existing data on the volume is accessible. Other errors are possible if you add volumes to a storage group and don't ICKDSF INIT them as SMS-managed, etc. There aren't any exits to ISMF that might help with this, although you could try customizing the ISMF CLISTs and load modules. This might be a subject for a SHARE requirement.

Re: I'm back
thanks Rob for your response. in answer to your questions: the file system i am using under z/os 1.9 is the same as the one under z/os 1.7. the z/os 1.7 lpar that is working has a copy of the file system (originally copied from the failing lpar), not the same one. there were no error messages - i had JZOS tracing and debugging on and did not see anything. TOMCAT/JBOSS would always stop at the same point after the same message was issued about the last thing it was doing. i forgot exactly what the message was (something to do with jndi i think) and we would have to go back to z/os 1.7 on the lpar in order to reproduce the problem. We are running RACF but there were no RACF messages issued. anyway, things are working now so if crypto was the problem, it may have been due to whatever differences were made for z/os 1.9. thanks again for your response. -Original Message- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Rob Schramm Sent: Wednesday, February 06, 2008 5:45 PM To: IBM-MAIN@BAMA.UA.EDU Subject: Re: I'm back Hi Eileen, I am sure that you got the same response from Steve and Kirk... huh?!? vbg That is a bit weird.

Re: RSV-XCEL Going Away
Hi, AOS works fine instead of RSVF for us. You can open a PMR or better just ask Level-2 to test this with you the next time you have a PMR active for something else. The IBM folks may enjoy the practice too some don't use it too often. Only gotcha I have seen is you can get a pop-up challenging you for the required authentication information and if you don't pay attention and miss it or just try to start over you can get all hung up. Watch for a prompt if you are behind a Web Proxy and make sure you know what format to key in your userid or domain\userid and password. You can supply the proxy information in a file if needed. I have not bothered or had as I don't use it very often so I just key it in. Here is a quote from a skeptical co-worker after he tried AOS and liked it better than expected. Start quote - I recently set up a session in AOS with a friend of mine from IBM CICS level II and it worked like a champ! He was able to do ANYTHING on our system, including read my EMAIL if he wanted to. CICS, TSO, Web USER INTERFACE,OUTLOOK, WORD etc., anything that is on our desktop, just like remote screen viewing or dialing to our PC from home. We had a few kinks to iron out BEFORE we got to that point however. And then I saw A.O.S., Now I'm a believer, There's not a trace, Of doubt in my mind! Here is a link to the procedure the CICS team will use to start a session with IBM. I STRONGLY suggest everyone get someone from IBM on the line and step through the process, before we have a PROD problem, like I did. End quote -- We have written procedures (hey we have procedures for everything...) Procedure to work online with IBM support using Assist On-site Process (AOS) June 5, 2007 AOS is a product from Tivoli much like Net meeting. IBM can share the keyboard to go ANYWHERE on our GEICO systems. TSO, WEB USER INTERFACE, CICS, OUTLOOK, you name it.. 1) Create a member on your C drive in NOTEPAD with the following name and one line entry: a. Name: proxy_ibm.txt b. Content: Proxy=xxPPROXY.x.xxx:80 --- your companies proxy 2) Go to the following Link with IBM on the phone: http://www-1.ibm.com/support/assistonsite/form1.html 3) You need our IBM site number xxx-. --- your companies IBM site# 4) You need a valid PMR-Branch-Country code. 5) IBM will give you the connection code. 6) Select the I Agree button 7) You will be prompted to download and run a browser plugin ibmaos.exe. The download may be blocked by your browser. To get around this select the click here option to download the file. 8) When the download is complete, select RUN. 9) You will be prompted for a Proxy Authentication.

Re: CPU time differences for the same job
The following message is a courtesy copy of an article that has been posted to bit.listserv.ibm-main,alt.folklore.computers as well. Neal Eckhardt [EMAIL PROTECTED] writes: We also had the batch window running so long that we were missing deadlines, and the CIO asked me to review the program stream to see what could be done to make it run faster (yea, good luck with that, they were all database programs and that's a different group). I told him that our new CPU (of essentially the same speed) that was due to arrive in two weeks had two processors rather than the four processors our current machine had, and the problem would probably be resolved with the installation of our new CPU. re: http://www.garlic.com/~lynn/2008c.html#88 CPU time differences for the same job the issue raised in post about disk thruput ... was over a period of years, processors got around 50 times faster in a period that disks only got 3-4 (maybe 5) times faster. Some claims are that the relative abundance of processor power led to a lot of (processor) implementation inefficiencies ... which could be relatively straight forwardly improved if anybody were to pay any attention. as circuit size decreased ... and processor thruput increased ... lots of signal latencies started to play larger and larger factor. the latencies (measured in number of processor cycles) that played a part in processor/disk thruput ... started to also dominant processor real storage ... and in much the same way that real storage started to be used as caches to compensate for disk thruput ... processor caches became more more important compensating for memory latency. in fact, using processor cycles as a measure of memory access time ... became one way of easily recognizing the problem (memories got faster, but processors got much, much faster) ... especially when references were to cache-miss and memory latency measured in possibly thousands of processor cycles. for little drift, recent posts mentioning improving application hitting (overnight) batch window limits http://www.garlic.com/~lynn/2008b.html#74 Too much change opens up financial fault lines http://www.garlic.com/~lynn/2008c.html#24 Job add for z/OS systems programmer trainee and for something totally different ... recent discussion of electronic commerce implementations running into problems hitting overnight window limit http://www.garlic.com/~lynn/2008c.html#85 Human error tops the list of security threats multitasking and multithreading have been used in the past attempting to mask disk access latencies ... keeping processor busy while something was wait for disk access. earlier in this decade ... there were chip hyperthreading solutions also looking at keeping processor functional units busy ... compensate/mask cache-miss memory access latency. the number of processor functional units weren't actually increased ... but there was hardware emulation of two processors ... basically two instruction streams, two sets of registers, etc ... but actual execution being done by common functional units. possibly the original in this genre was a project to do a dual i-stream implementation for 370/195 (i.e. emulation of two-processor smp) ... which never actually shipped as product. the issue was that 195 had a 64 instruction pipeline that could execute instructions concurrently with common set of functional units. the pipeline could go a long way towards masking the difference in processor thruput and memory latency (w/o actually having a cache). The problem was that the amount of processor logic/memory supporting this function was rather limited. These days, chip implementations may have several hundred positions for dealing with branch prediction and speculative execution (and backing out instructions not actually branched to). In the 370/195, except in very special cases, branches would drain the pipeline. Normal codes, with typical branch useage, resulted in 195 running at half peak thruput (it took careful programming to keep 195 operating at peak thruput). The idea behind the dual i-stream was to have two sets of independent instruction streams ... both operating at half peak thruput ... but combined, capable of keeping the 195 pipeline fully stocked with instructions. misc. past posts mentioning dual i-stream as (one of the) mechanism for compensating/masking increasing memory latencies (as measured in processor cycles) http://www.garlic.com/~lynn/94.html#38 IBM 370/195 http://www.garlic.com/~lynn/99.html#73 The Chronology http://www.garlic.com/~lynn/99.html#97 Power4 = 2 cpu's on die? http://www.garlic.com/~lynn/2000g.html#15 360/370 instruction cycle time http://www.garlic.com/~lynn/2001j.html#27 Pentium 4 SMT Hyperthreading http://www.garlic.com/~lynn/2001n.html#63 Hyper-Threading Technology - Intel information. http://www.garlic.com/~lynn/2002g.html#70 Pipelining in the past http://www.garlic.com/~lynn/2002g.html#76 Pipelining in the past

Re: Analysis: New IBM mainframe won't end battle for Big Iron's soul
-Posted by Ed Gould - February 6, 2008 -Original Message- Subject: Analysis: New IBM mainframe won't end battle for Big Iron's soul http://www.computerworld.com/action/article.do? command=viewArticleBasicarticleId=9061140source=NLT_PMnlid=8 February 6, 2008 (Computerworld) IBM is expected later this month to announce its next-generation System z mainframe, its first update since the release of the z9 three years ago. It is promising improved energy efficiency, security and 50% more capacity in its new hardware. But what this new mainframe won't change is the ongoing battle for IBM mainframe customers, who can easily spend millions of dollars on a new system and are continually wooed by alternative and much less costly platforms. I thought there were several interesting paragraphs here: Tony Parziale, the CIO of the 46,000-student college in Lake Worth, Fla., said the four-socket Intel system that is replacing the z890 will cost about $30,000. While his IT staff will miss some of the mainframe's tools, the new system runs faster than the mainframe, and the software cost less, he said. Is the new Intel system really running everything that the z890 ran? What about security and RAS? And it runs faster by what measurement? Energy savings is a big reason for workload consolidation these days, and it is why IBM will likely give a lot of attention to the ability of its mainframes to host thousands of virtual servers in limited data center space. Yes, and this is what will keep the mainframe alive. Despite IBM's efforts, mainframe can be a chore to handle. According to the Share survey, approximately half of those responding said they rely on hand-coding by developers to get access to business information, a time-consuming and potentially error-prone process. Hand coding by developers? What does that mean? That they have to write programs. Oh my, that might take a little thinking and work. A percentage that high indicates that integration is a hard problem, said Pam Taylor, a vice president of Share and an IT architect at a large company that she asked not be identified. Does Pam monitor this board? Come on, it says right on the Share web site that you work for Sterling Commerce. Oops, did I let the cat out of the bag. :-) Although Michael sees distributed systems improving, he believes that the mainframe's total cost of ownership is less when support costs and technological advantages, particularly in virtualization and security, are considered. This is so true. The problem is that most upper management doesn't take all the costs of a server farm into account when making decisions on what platform they want to use. Server administrators are more likely to reboot if there's an issue, while mainframe operators, if asked to reboot, will likely reject the idea and focus on first understanding the problem and finding an alternative means to address it, he said. Not necessarily true. Just watch what happens at a bank of the server controlling the WEB for the Online Banking comes down. Someone's head will roll. Also, if something is hurting the mainframe we don't stand around for too long scratching our heads trying to figure it out. A work around better be found pretty quick.

Re: CPU time differences for the same job
The fact that two runs of the same work on the same system at similar times may vary by 10%-20% in CPU time is what I would call completely unreliable. That would make all Capacity forecasts completely unreliable, since getting it within 20% is considered a job well done. 1%-2% can be called variable, but 10%-20% is a major difference that cannot be simply accounted for, except by throwing out low and high values from multiple runs as was suggested earlier in the thread But, if you're using it for chargeback, in the real world, you don't have the luxury of throwin it out. - Too busy driving to stop for gas! -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: WLM for toddlers
Way back when we first implemented stored procedures under WLM the first problem that surfaced came from Top Secret. The user that invoked the SP was stopped via a security violation. Top Secret issued a 1C-06, no access to the facility called STC. Took us a while to figure it out but we saw that SPs entered the system as baby STCs.

Re: WLM for toddlers
Ted, actually you are the one mixing the terminology. WLM application environments (AE's) are either available or quiesced. When an application (in the DB2 stored procedure/UDF case, DB2) requests a connection to an AE, if the AE is quiesced, the request is failed Okay. It's been awhile. I mis-used the terminology. But, your clarification states the same thing I was trying to say. The WLM does not activate a quiesced AE, automaytically. - Too busy driving to stop for gas! -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
how to abuse a STC for fun and profit.
I am not suggesting doing this. But it works, strangely. Create a started __job__, say named STC ./ ADD NAME=STC //STC JOB ... //PROCLIB JCLLIB ORDER=(PROCLIB) //RUNIT EXEC PROC=MEMBER // You can now use this to run any JCL member from any JCL library as a started task. Well, assuming that the JCL is set up to run as a started task. S STC,JOBNAME=X,MEMBER=X,PROCLIB=MY.PRIVATE.STCPROC So, I'm easily amused. You don't really need the JOBNAME=. I just put it there so that the jobname and the member name would be the same, as I am used to. I also tried: ./ ADD NAME=STC //STC JOB ... //PROCLIB JCLLIB ORDER=(PROCLIB) //RUNIT EXEC PROC=JOBNAME // I had thought that S STC,JOBNAME=X,PROCLIB=MY.PRIVATE.STCPROC would execute member X from MY.PRIVATE.STCPROC because I specified a JOBNAME=X. But it tried to run the JES2 proc instead. I guess the JOBNAME variable was not resolved when I thought it would be. The output looks a bit weird. Unfortunately, it would wrap if I included it in the email.

SMP/E ++PROGRAM vs ++LMOD
Hi. I'm having a problem building a usermod that should replace an installed source, assemble it, and replace the existing load module. The source was during product installation defined as ++SAMP(name) and the load module as ++PROGRAM(name). My question is if there is a way to have the usermod replace the SAMP entry, assemble and link it, and replace the installed PROGRAM entry. If I use standard JCLIN to define the process it generates ++SRC and ++LMOD entries, but installs correctly. The problem is that if the vendor ships a new version of any of these two objects, the conflict will not be spotted by SMP/E who knows my alteration using different data element names. I guess my problem here is two-folded: how to get a ++SAMP element assembled without creating a ++SRC element, and how to get the program object created as a ++PROGRAM element instead of ++LMOD. I've started to believe that I need to do the assembly outside of SMP/E's control, am I correct?

I guess you have to scribble down or otherwise remember the original RMID values and use UCLIN again to reset them as needed?? -- Edward E Jaffe Phoenix Software International, Inc 5200 W Century Blvd, Suite 800 Los Angeles, CA 90045 310-338-0400 x318 [EMAIL PROTECTED] http://www.phoenixsoftware.com/ -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Engineering changes and software version or service level
All: My current client is about to apply several microcode changes that are way overdue (about 3 years worth) to bring their 2066 up to level. To make things less comfortable, they are still at the 1.4 version of z/OS (I'm working to get them onto 1.7 and eventually 1.9). My question is how (if any) do I check whether or not any specific EC/MCL requires a specific level of z/OS or specific PTFs? The field engineer has provided me a list of the ECs/MCLs he expects to add, but provided no reference to any related software requirements. The client is running a basic sysplex with two LPARs, both at z/OS v1.r4 with toleration PTFs for v1.r7. Many of the MCLs refer to coupling facility fixes, but because we are a basic sysplex, these should not be a concern. Any hints or suggestions?

Re: Why isn't OMVS command integrated with ISPF?

We've recently installed z/OS 1.9. Admittedly I'm easily amused, but I'd give this a coolness factor of 3.01296 out of PI. (If you don't have 1.9 yet, a window pops up with a progress bar that moves from 0 - 100 percent.) I did this quite by accident this afternoon -- bad finger fumble. And I watched while the progress bar began to creep across the window with aching slowness. Curses! But wait; there appears to be an escape: the key legend at the bottom of the popup says, PF12 - Cancel. I press PF12. Nothing happens. But I've learned to deal with these silly-assed 3270 terminals. I press RESET. Nothing happens. I press RESET again, and the keyboard unlocks; I'm getting there; I press PF12. The keyboard locks again, but nothing else happens. The progress bar continues its weary journey. Finally it reaches 100%; the Cancel takes effect and the data set list vanishes. Is it me, or is it them who fail to understand the fundamentals of cancelling a long-running process? Or should I have placed the cursor in the popup before pressing PF12? I'll try that next time. Regardless, if it's going to cancel the parent window display, it would be a courtesy to the customer to do that immediately rather than waiting until the popup exits. Don't these brilliant young overseas programmers know how to wait on multiple ECBs? -- gil -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Better version of PDS. PDSE is created to solve some problems with PDS. One of the problems which are solved in PDSE is improved directory integrity. There is no mechanism to stop the PDS directory from being overwritten if a program mistakenly opens it for sequential output. If this happens, the directory is destroyed, and all the members are lost.

Re: I'm back
Eileen, I am glad it is working. I am more than a bit skeptical that ICSF was somehow interfering with the startup. If you come across something like it in the future, the other thing I can suggest is turning on some of the debugging for the JVM. If JZOS had ceded control over to the JVM, then it may have been something with the JDK. I know that with Tomcat 5 there was a weird bug with the startup that would only occur occasionally. Ah well.. you are on 1.9 and life is good. As I guy I used to work with would say... It's a fluke. vbg -Rob -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: Change DD SPACE-Allocation at runtime
On Feb 7, 2008, at 8:49 AM, Steve Pryor wrote: As previous posters have noted, you can change the secondary by doing an OPEN-J and modifying the JFCB at execution time, but of course this would have to be done by the application opening the dataset. You can also change the secondary for an existing dataset by specifying it in the JCL but the question really was how to do this without changing the JCL. There is also, of course, no way to change the primary space specification outside of JCL, since allocation occurs before execution. I am puzzled by the person who asked the question. If you do NOT like the allocation you can delete the data set in question and use dynamic allocation to allocate the data set the way you want to. All from inside your program, what's the big deal? You can feed the volser and everything else (for DASD) in DYNALLOC. Why go messing around with open type=j (its neato but IMO over complicated ) Besides it *MIGHT* get messy in an SMS environment so no matter what you do it might be overridden by SMS (or other package).

Re: tcpip, vary obey command failed : exclusive control
J R, I did several tests. The obey fails if I try a nonexistent member ( logically ) and if I use a dataset for which TCP/IP is not authorized. Did you test sequential versus member of a PDS? Nope, I didn't test sequential, because that would need a sequential dataset that TCP/IP is authorised to access. I am allowed to do a lot on our test-LPAR's, but changing security isn't one of them :) -- Maarten - ATTENTION: The information in this electronic mail message is private and confidential, and only intended for the addressee.
