Re: About dispatching process
Peter, as far as I know the restart interrupt from the HMC with options abend-resume-repair are supposed to correspond to the spin(resume)-retry(repair)-term(abend) options of automatic exspin recovery. If you ever want to test this again, put your PHUNLOOP job into sysstc - improves the chances of it running quite a bit! :-) Santosh, the big dispatcher rewrite that got rid of running tcb chains in every address space once and for all occured with MVS 5.1. That release introduced a completely different mechanism (the WEBs) for indicating that work is ready to run. There have been bits and pieces around this since then, but that design is quite a solid one. And there are (and were) quite more dispatchable units of work than 'just' tcbs; just look at macro IHAWEB for the different types. (Peter was faster than I on this!) And given that an lpar these days uses logical processors, I would be really reluctant to even *attempt* to introduce a machine check to a processor. Whenever I have to stop the processors for a test lpar to see the psw and get an idea if it is doing anything or juat waiting , we have a discussion if that will affect other lpars sharing the same physical processor!

Re: About dispatching process
as far as I know the restart interrupt from the HMC with options abend-resume-repair are supposed to correspond to the spin(resume)- retry(repair)-term(abend) options of automatic exspin recovery. No, there is no connection. Abend/Resume/Repair for the restart interrupt key was introduced in MVS/370 SP1.3 as part of a 3033 RAS and performance enhancements package (the 3081 had slipped, and we had to revive the lagging 3033 sales). The Repair option is a collection of things which never proved to be very useful. This is what Repair is supposed to do: Causes limited system diagnosis and repair. - Call Supervisor Analysis Router (IEAVESAR) to check and repair critical data areas. - Look for system non-dispatchable and schedule an SRB routine to reset the condition. - Look for WTO queue element depletion. - Check for system out of work (no batch and no TSO users), and inform the operator with message IEA501I via WTO. - Schedule SRB for IOSVRSTS to analyze I/O. - Return to interrupted work. And this is what IOSVRSTS does: This module is scheduled by the restart FLIH extension module to run under an SRB. It does the following: . Redrives all connected subchannels by invoking the IOSINTRP macro to simulate an interrupt via a LPSW, which in turn causes the subchannel to be re-driven. . Scans the MIH message queue and notifies the operator, through the disabled console communications service, that MIH conditions exist on paging devices. If IOSVRSTS finds more than one message for the same condition on the same device, it notifies the operator only for the first occurrence of the message. If the disabled console communications routine fails, IOSVRSTS stores the device number in the PSA (PSAWTCOD) via the LOADWAIT macros used by the associated Loadwait/Restart service which places the system in a restartable wait state with a hexadecimal wait state code of 116. . Terminates any address space in which I/O purge is waiting and the purge quiesce counter is not equal to zero. IOSVRSTS terminates the address space by issuing CALLRTM TYPE=MEMTERM with a hexadecimal abend code of 0AE. I was the function tester for that whole RAS package in SP1.3. The item to memterm address spaces which are waiting in I/O Purge was rather controversial among the development team. It seemed to me like a bad idea, but I didn't have much influence on the designers 27 years ago. It still seems like a bad idea, but since I doubt that this Repair function ever got used much outside of my testing, I haven't bothered to get it deleted. (I do have a bit more influence now).

Correct? 2) These 2-byte entries correspond to each device # entry. What is meant by the term 'valid' here? Bit 0 being 1 means 'not valid' but what does that mean? Is there no volume mounted at that address? Or do you have to look at bit 1 to see if this device number is associated with the specified input UNIT name?

The machine sorted strictly sequentially, while the computer had bubble or shell sorts that were more efficient. maybe tape sorting was slow, but disk sorting should've been fast. If the machine had some core ie 128 k, then plenty of work could be done within the CPU at very high speed. simple example would be fortran student jobs. the master of the program is the individual student's card deck. the student has access to only fortran compile execution capability ... and compile would be one pass of the input card deck. when i started, the univ. had 1401 that was used as unit-record front-end to 709. the card decks (potentially multiple student jobs) would be collected in card tray. when the tray approached full (our every couple hrs), the tray of cards would be read by the 1401 and transferred to tape. the tape would be carried to 709 tape drive and processed (sequentially, each job compiled and executed) with output going to another tape. When processing finished, the output tape would be moved to 1401 and results printed. The operator would take the printed, fan-fold output, burst it ... i.e. tear it into individual jobs, match the bursted print output with corresponding original card deck, wrap the bursted print output around the input card deck (with rubber band) and place it in output bin for student pickup. there were some administrative jobs that used sort ... but that frequently had trays and trays of cards ... written to tape .. and then multiple tape sort (with intermediate tape files) that ran for extended period of time. i did write part of an application that was used for class registration. 2540 could not only read holes ... but also had the capability of reading sense-marked cards (i.e. no. 2 pencil marks in little boxes on cards). the 2540 had two feeds from the sides with five card stackers in the middle. one side read cards and could select two of the read-side stackers or the middle stacker, the other side punched cards and could select two of the punch-side stackers or the middle stacker. class registration had all these sense-marked cards ... which would read and place in the middle stacker. if the processing found some problem with a card ... a blank card from the punch side would be punched behind the recently read sense-marked card (with some problem ... before the next card would be read/processed) standard processing had an operator removing cards from the stacker and placing in card trays. all of the class registration sense-marked cards were plain manilla. the punch cards were loaded with cards that had yellow (or sometimes red) across the top band of the card. once all class registration cards were processed ... there would be multiple trays ... sporadically sprinkled with yellow top-edge cards ... clearly identifying the registration cards with some kind of problem. qd conversion of gcard ios3270 to html http://www.garlic.com/~lynn/gcard.html reader/punch channel program command codes http://www.garlic.com/~lynn/gcard.html#23 system/360 model 30 machine room, 2540 is seen in middle, in front of the tape drives and partly obscured by 2311 disk drive. the card reader (feed) is on the right and the punch is on the left, the five output stackers are in the center http://www-03.ibm.com/ibm/history/exhibits/mainframe/mainframe_PP2030.html system 370 model 40 machine room, 2540 is in upper middle http://www-03.ibm.com/ibm/history/exhibits/mainframe/mainframe_PP2040.html better picture of 2540 on the right with somebody loading deck of cards to be read http://www.cs.ncl.ac.uk/events/anniversaries/40th/images/ibm360_672/slide19.jpg -- 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: Dynamic ISPF panels?
Sorry Dave, Nothing there about how to do scrollable menus or dynamic areas. Scrollable menus take the work out of your hands for handling different number of rows in the display. Dynamic areas put the work of defining the actual format of the panel in your code. The IBM provided SISPPENU dataset is a good source for scrollable menus. For dynamic areas you need to find the code source, not just the panel.

The answer is No. APF processing does not, and will not be changed to, do anything with the actual data set. And during IPL it really is not in a position to do so. The APF entry is merely a data definition. This is precisely why there is a health check. SMS managed SMS managedSuccessful ===!!! The above entry denoted with ===!!! is wrong.

Re: About dispatching process
On 10/24/07, Vernooy, C.P. - SPLXM [EMAIL PROTECTED] wrote: I think what the manual says is the same as what you said. In a MP system, a disabled loop is observed as a spin loop by other processors. This is not exactly true: A disabled loop by itsself will not generate a problem. However, other processors will regularly want to talk to the disabled processor, via the SIGP instruction. The calling processor will spin (in a disabled loop, therefor spin loop) waiting for an answer. The disabled called processor will of course not answer and the calling processor will detect this and generate an excessive spinloop time out condition. So the spinloop is a normal, short duration, situation; an excisive spinloop timeout is a condition detected by an active processor, where an other processor does not answer. This can be for many reasons, being disabled, hardware problems etc. etc. Have a look at Initialization and Tuning Reference, member EXCPATxx, for more information on spinloops. This leads me to reconsider my understanding about the process of getting a spin lock. I used to think what SETLOCK does is just keeping on check the lockword and running disabled. Then, what is the difference between a spin loop and a disabled loop? So my guess is, what SETLOCK does is a 'timed disabled loop'. That is, most of the time it'll loop disabled but not forever. It will enable the processor regularly thus an excessive spin loop can be detected and handled by system. Did I miss something here? I have another question about RB queue/chain. (A little off-topic but at least it is involved in dispatching process -_- ) Here is a RB chain after a new RB is added: TCB -- RB1 -- RB2 -- RB3 I think RB1 is the oldest and RB3 is the newest but is it true? Then this TCB is dispatched and the RB pointed by TCBRBP will be executed. Which one? I think it should be RB3 ( the newest) but I'm not sure.

APF FORMAT=DYNAMIC
Is anyone still not using FORMAT=DYNAMIC for their APF list? It isn't the default so you'd have to have the proper statement in your PROGxx to get it. Maybe some day we'll change the default, though it's not a really big deal since if you start as STATIC you can always switch to DYNAMIC if you find a need. The only real benefit of starting as DYNAMIC is that you don't have the initial storage-use below 16M for the static APF list.

You can use an extended format dataset for it. You have to define an data class in which you add an value to the volume count parameter en specify DSN TYPE EXT.

Sorting files too big for disks wasn't a problem that ended in the card-sorter days.The interesting one is when the files to be sorted were multiple tape files. The solution was to sort what could fit on a tape - repeating on multiple tapes until the file was spread about a bunch of sorted tapes. Then merge the tape files.

Re: ICKDSF - PARMS

Re: VARY too many devices offline
Personally, I'd view this as a management issue, not a technical issue. The root problem in my opinion was the need for an operator to issue the command in the first place. When you require human intervention, errors are to be expected and therefore tolerated. There are a number of such commands where a single keystroke error can and will bring you down. For example, try the command $P PRINTER1, but hit enter rather than the space bar. (That is recoverable, but it is unlikely anyone will discover that until after the IPL.) So, yes, reassign the operators (all of them) and don't replace them.

Re: About dispatching process
If RB3 is pointed to by TCBRBP, RB3 is newest and is the top RB. TopRB get executed first when the TCB is given control. The way it’s chained is RB3-RBLINK field points to RB2. RB2-RBLINK points to RB1 and RB1-RBLINK points to the TCB. I think to obtain a spin lock (unconditional request) the SETLOCK routine first disables then goes into a spin loop to execute a sequence of instructions. The instruction sequences are tests-for-and-if-available-obtain-the-lock, return if successful, enable for interrupt, then disable, retry the lock obtain. So in that sense the spin loop is the same as the disabled loop. The enablement is accomplished via the WINDOW macro which enables for external interrupts and immediately disables so that emergency signal maybe received. The number of time to loop I think is limited (the detection) by a value set in some system area, possibly the CVT. (Of course somewhere within the instruction sequence, it would have to check for hierarchy.)

In a MP system, a disabled loop is observed as a spin loop by other processors. This is not exactly true: A disabled loop by itsself will not generate a problem. However, other processors will regularly want to talk to the disabled processor, via the SIGP instruction. The calling processor will spin (in a disabled loop, therefor spin loop) waiting for an answer. The disabled called processor will of course not answer and the calling processor will detect this and generate an excessive spinloop time out condition. So the spinloop is a normal, short duration, situation; an excisive spinloop timeout is a condition detected by an active processor, where an other processor does not answer. This can be for many reasons, being disabled, hardware problems etc. etc. Have a look at Initialization and Tuning Reference, member EXCPATxx, for more information on spinloops. his leads me to reconsider my understanding about the process of getting a pin lock. I used to think what SETLOCK does is just keeping on check the ockword and running disabled. Then, what is the difference between a spin oop and a disabled loop? So my guess is, what SETLOCK does is a 'timed disabled loop'. That is, most f the time it'll loop disabled but not forever. It will enable the rocessor regularly thus an excessive spin loop can be detected and handled y system. Did I miss something here? have another question about RB queue/chain. (A little off-topic but at east it is involved in dispatching process -_- ) Here is a RB chain after a new RB is added: TCB -- RB1 -- RB2 -- RB3 I think RB1 is the oldest and RB3 is the newest but is it true?

Re: Out of space uploading to a UNIX directory
Hal had a couple good points that I failed to mention. (See, I said
that if I said something wrong, it would be corrected! :-) )
Here's what he said so I can comment on them.
snip
Technically sounds good, except I don't think IEBGENR is the right tool
for that job; I'd go with DFDSS. More, other users of the /u system

/snip
Hal, I'm the only one at my site who even gets into OMVS - most
everybody else won't even acknowledge that Unix services exist on the
Z. Because of that, nobody would even notice if I took the /u
filesystem offline.
I believe either DFDSS or IEBGENER should be able to copy the data from
one to the other but doing what you suggested he wouldn't even need to
copy anything.
Jerry, to take what Hal said, you could simply delete the huge file from
the /u filesystem to reclaim the space. Not knowing whether this is a
permanent or tempory situation with this big file, setting up the second
filesystem might be the way to go, especially if you have others using
the /u filesystem like Hal mentioned. If you want to just build a new
filesystem under the /u directory, that is less disruptive than my
original suggestion. Say, for example, you want to build /u/jerry, you
can do this:
1 allocate the new dataset for the new filesystem (from the MVS side)
for example allocate MVS.THIS.IS.JERRYS.DATASET
2 build a directory under the /u tree mkdir /u/jerry
3 from a TSO prompt (or option 6) mount the new filesystem mount
filesystem('MVS.THIS.IS.JERRYS.DATASET') mountpoint('/u/jerry')
type(hfs)
You should now be able to get to the newly allocated space by simply
cd'ing into /u/jerry (or FTPing into that directory).

How can I read JESJCL from a batch program?
I have written a program that reads in 80 byte cards and performs symbolic variable substitution at execution time. This program allows us to create control cards that are environment generic and has greatly reduced the number of redundant control cards than need to be maintained. It can even dynamically allocate and write multiple output cards in a single execution. This program works very well and has been well received by our staff. The only downside with this program is that the symbolic values have to be passed into the program on the parm. The 100 character limit has been a bit of an annoyance with this approach. I would like to enhance this program to avoid to necessity of passing the symbolic values through the parms. I am certain I can successfully get the information I need by parsing the JESJCL. What I have not been able to find out so far is where the JESJCL data is? Is this in an MVS data area? Is it in a dataset allocated to the job? If someone can help me find out how to read the JESJCL, I will be happy to share the code with the world. For that matter I can share what I have now if anyone is interested.

Re: Out of space uploading to a UNIX directory
I think someone covered this, but it would be best for you to have separate mount points for different directories/users under /u/ (i.e. /u/steve/ would have it's own dataset, /u/mike/ would have it's own dataset). That being said, another way that you can expand the size of your dataset, assuming you haven't hit a serious wall, is with the confighfs command (look it up in your version's Unix System Services Command Reference). Do something like: confighfs -x 50c /u/ to (attempt to) add 50 cylinders to the dataset where /u/ is mounted. Aaron On Thu, 25 Oct 2007 11:18:40 -0500, Support, DUNNIT SYSTEMS LTD.

Re: S028 after ALESERV
Looks like a hardware error, doesn't it? 028 Explanation: The system could not complete a paging operation for one of the following reasons: a.. A permanent I/O error occurred during a page-in or swap-in operation. The data being paged in or swapped in is lost. b.. A page cannot be accessed on auxiliary storage because of a previous I/O error. c.. An indeterminable error occurred during management of central storage paging. The system ends processing. Register 15 may contain a reason code. d.. The operator canceled a Time Sharing Option Extensions (TSO/E) user before the TSO/E logon completed. e.. An address space referred to a pageable link pack area (PLPA) page that contains noncontiguous code or large constant areas. The system had already detected this error and issued message IEA928I. See message IEA928I. f.. The system found an unexpected error while processing a swap-in or swap-out request. The error is described by a reason code in register 6. g.. The only current copy of a page resides in a defective frame on expanded storage. An error occurred when the system tried to bring the page into central storage from the defective expanded frame. h.. An I/O error occurred when the system wrote the page to auxiliary storage. i.. An I/O error occurred when the system attempted to transfer data from a data-in-virtual object into a mapped window page. System Action: The system abnormally ends the current task or address space. Operator Response: If the system issued message IEA928I, see the operator response for that message. Otherwise, notify the system programmer. System Programmer Response: Look for messages indicating a hardware error. If you find any, contact hardware support. Search problem reporting data bases for a fix for the problem.

Re: Java Support question

We have multiple programming areas that are requesting we put up a very specific version of Java or SDK. Let me be specific we have installed a ddef SAJV15D which has a path of /service/tgta/usr/lpp/java/J5.0_64/IBM/ and we have multiple versions of java installed. Originally we used SMP/E to install Java. But since each update is a complete replacement, we really found no benefit. When a new version was needed, the requirement came from the WebSphere group and they always requested the updates by names like 1.4.2 SR5. Now here is the real life challenge. We are installing IBM's EDK (for data encryption key store) they have a very specific JDK/SDK . We can easily copy it to its own directory but how does one maintain it in an automated way? Not sure what you mean by maintain it in an automated way? Now the question is when your told to install a specific version, we run RSU monthly etc but if it doesn't know about it in the SMP/E zone how do you do it? You can't. But if you want, you can create different target zones for each release... but we need different levels of the same release so that just doesn't work (see above). Since you are told to install a specific version (as we are), then that is what prompts you to get something new. Or you can just look periodically at IBM's web site: http://www-03.ibm.com/servers/eserver/zseries/software/java/ Here is what we do. We support a system level default Java. The level is at the lowest common denominator (example: 1.4.2 31-bit). It gets mounted at the default mount point of /usr/lpp/JAVA. We put JAVA_HOME and other environment vars in /etc/profile to point to the default. This is usually good enough for the majority of our Java users. The OS team supports the default version. We used to support all of the versions, but since WebSphere drove most of the requirements, they started installing and maintaining their own versions. For WebSphere, they have their own environment variables and point at a static local directory where we install z/OS UNIX software. In production and QA, that directory is a symlink pointing to where they have the desired version of Java. That way, they just update the symlink to swap new levels in. Our WebSphere development LPAR often has 3 or 4 different levels of Java mounted. That same directory structure is used for all the other levels / flavors of Java as well. They get pointed to via environment variables in the process(es) that invokes them if they don't want the default. For example, we are installing a product that required 1.4.2 SR7 (IIRC). That application runs in batch and while it could use BPXBTCH, JZOS was preferred and is being used. JZOS gives you a convenient way to specify the environment variables to point to the right level of Java. Another product being tested needed V5 64-bit.

Is it in a dataset allocated to the job? You don't say whether you're using JES2 or JES3. I've only worked with JES2, for which the processing is as follows: JCL is read by a reader (with an optional exit) and saved to the spool in the JESJCL pseudo data set. In-line data cards are extracted and written separately. The job is passed to the Converter/Interpreter, where JCL is read, passed to the IEFUJV exit, and processed into OS JobQueue format, passed through an optional text exit (not intended for user access), and written as another pseudo data set. When the job executes, one or more times, the JobQueue records are read and converted to system control blocks (JCT, ACT, SCTs, SIOTs, etc.) in virtual memory. If you wish to change the JCL, you need to do so in the JES reader exit, or in IEFUJV. It is possible to read the JESJCL data set at a later time (for code look at the Q command at cbttape.org), but any changes you make will be ignored. The big gotcha is the annoying little detail that the reader and converter need not run on the system the job will execute on. To make the changes at execution time, you could use the IEFUJI (job initiation exit), and read and possibly alter the text records in JobQueue format. If you look at the group archives, you'll find a slew of messages regarding the resolution of symbolic parameters, which seems to be what you're driving at.

When the job executes, one or more times, the JobQueue records are read and converted to system control blocks (JCT, ACT, SCTs, SIOTs, etc.) in virtual memory. If you wish to change the JCL, you need to do so in the JES reader exit, or in IEFUJV. It is possible to read the JESJCL data set at a later time (for code look at the Q command at cbttape.org), but any changes you make will be ignored. The big gotcha is the annoying little detail that the reader and converter need not run on the system the job will execute on. To make the changes at execution time, you could use the IEFUJI (job initiation exit), and read and possibly alter the text records in JobQueue format. If you look at the group archives, you'll find a slew of messages regarding the resolution of symbolic parameters, which seems to be what you're driving at. If you only have a single system, the easiest place to make substitutions would in IEFUJV or the JES reader exit, and forget about the JESJCL data set.

Shared DASD and PAVs
I've got a few PAV question for the hardware gurus out there. I define all of my DASD to my production LPAR (these are monoplexes) as WLMPAV=YES, alias and base and I have WLM managing them. I have another LPAR that accesses some of these volumes (actually it is the one accessing these volumes 99% of the time). In this LPAR I only have the bases defined no aliases and do not have WLM managing these devices including WLMPAV=NO for the devices defined in the OS. The reason we did this was for ease of volume maintenance, make them all PAV and not worry about it. Really the only access of these volumes from the producation LPAR is for backups once a week. I'm curious what the recommended way of defining these devices is for a situation like this? Should I be setting these devices as WLMPAV=NO on the production system (which blows the ease of maintenance idea). Would issues could I run into with the current setup?

This program allows us to create control cards that are environment generic and has greatly reduced the number of redundant control cards than need to be maintained. It can even dynamically allocate and write multiple output cards in a single execution. This program works very well and has been well received by our staff. The only downside with this program is that the symbolic values have to be passed into the program on the parm. The 100 character limit has been a bit of an annoyance with this approach. I would like to enhance this program to avoid to necessity of passing the symbolic values through the parms. I am certain I can successfully get the information I need by parsing the JESJCL.
