Re: JES3 job ids
On all the JES3 systems that I have seen (since OS/390 V2R5) all jobids have always looked like JOBx for jobs, STCs and TSUs. The entries S0xx and J0xx in the presentation may originate from STCs and TSUs that were running under a secondary JES2 on the same system. But Ed Jaffe will probably let us know if he has a different explanation.

But ISTR that when JES2 went from a 4-digit numeric suffix to 5 (does anyone remember the old format?), it was made an installation option whether the numeric part reset at 100,000 or at 10,000. Our site chose 10,000 because we were not suffering a name space constraint and there was some compatibility concern. (Terse format of operator commands?) So perhaps the format is a configurable parameter. (I ranted lately, "I hate options!"

IODF "soft activate" to "clean up" UCBs after a tape library problem?
We had a problem with our tape library. We are sure exactly what, yet, but one CE indicated that he _thinks_ it might be a "flaky" fibre switch. The remote support engineer said that one thing he suggests to do is a "soft activate" (software only) of the current IODF. I.e. do: ACTIVATE IODF=nn,SOFT=NOVALIDATE This is to make sure that the tape UCBs don't have any sort of error status in them from the z/OS side. What I've always done, in the past, was to vary the SMS library offline, then back online. I can do this because we only use the ATL, physical 3590 drives, for our disaster backups. These run starting about 06:00 until maybe 11:30. My question is what do the ACTIVATE above do. I've never heard of such a thing before. Not that I'm saying it won't do anything, I'm just admitting to ignorance. -- There is nothing more pleasant than traveling and meeting new people!

Re: IODF "soft activate" to "clean up" UCBs after a tape library problem?
SOFT Specifies a dynamic change to the software I/O configuration, which updates the I/O configuration only to the operating system. No hardware changes are attempted. However, you may specify whether hardware validation is requested (VALIDATE, NOVALIDATE). To change a software and hardware I/O configuration dynamically, omit the SOFT keyword. When you specify SOFT, you cannot specify FORCE. You can specify the following suboptions: VALIDATE When you specify SOFT without any parameters, it is the same as specifying SOFT=VALIDATE. This allows you to specify that the system is to validate that any specified hardware elements to be deleted are offline and available, and that there is sufficient HSA space available to accommodate the hardware changes. When a dynamic change is made to the I/O configuration for a processor complex running in LPAR mode, a change to the software I/O configuration is performed for the first N-1 logical partitions, followed by a hardware and software change for the Nth logical partition. By specifying the SOFT keyword (or SOFT=VALIDATE) when changing the I/O configuration on the N-1 logical partitions, you can determine early on whether there will be sufficient HSA space available for the subsequent software and hardware I/O configuration changes on the Nth logical partition. NOVALIDATE indicates that no validation of hardware changes is to be done. Does that help?

z/OS physical memory usage with multiple copies of same load module at different virtual addresses
Hello, I had a question about how z/OS handles physical memory for the same load module that is loaded at different virtual addresses in different virtual address spaces. For example, let's say on the same z/OS system I have the following: CICS region A that has load module B loaded at virtual address x'3F400010'. CICS region B that has the same load module B loaded at virtual address x'3D400020'. More than likely there will be some differences in that same load module that has been loaded at different virtual addresses, since things like ADCONs and VCONs will resolve to different virtual addresses when the load module is brought into memory. However, there will probably be many virtual pages that are also identical between the two modules, if nothing in that virtual page needed to be adjusted by the loader. My question is, does z/OS have any functionality to detect the virtual pages that would be identical for these 2 load modules and then adjust the virtual page tables for CICS region A and B to point to the same physical frame and drop the duplicate frame? So for example, if the first 4k virtual page of load module B in CICS region A at x'3F400010' and the first 4k virtual page of load module B in CICS region B at x'3D400020' had the same data in it, would z/OS recognize this and cause the page tables for CICS region A at x'3F400010' and page tables for CICS region B at x'3D400020' to be adjusted to point to the same physical frame and then drop the other duplicate physical frame? I was under the impression that the answer was no, but one of the SYSPROGs here thought that z/OS had functionality to detect identical physical frames that hold instructions that different address spaces might be using and then do some physical memory savings like I am mentioning above. I tried doing some internet searches on this topic, and could not find any hits. If z/OS is doing this and someone has links to where this documented, I would appreciate a point in the right direction.

Re: z/OS physical memory usage with multiple copies of same load module at different virtual addresses
While this is not quite the same thing as 2 CICS regions using a page of the same load module, take a look in Principles of Operation which talks about how "fork" is handled. From page 3-15 of August 2010 version of POP: The suppression-on-protection function is useful in performing the POSIX fork function, which causes a duplicate address space to be created. The following discussion pertains to when enhanced DAT does not apply, or when enhanced DAT applies but the format-control (FC) bit in the segment-table entry is zero. When forking occurs, the control program causes the same page of different address spaces to map to a single page frame of real storage as long as a store in the page is not attempted. Then, when a store is attempted in a particular address space, the control program assigns a unique page frame to the page in that address space and copies the contents of the page to the new page frame. This last action is sometimes called the copy-on-write function. The control program sets the DAT-protection bit to one in the page-table entry for a page in order to detect an attempt to store in the page. The control program may initially set the DAT-protection bit to one in a segment-table entry to detect an attempt to store anywhere in the specified segment. regards, Joe D'Alessandro -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

re: http://www.garlic.com/~lynn/2014i.html#66 z/OS physical memory usage with multiple copies of same load module at different virtual addresses a little more topic drift. part of the MVT storage allocation issues was with contiguous storage allocation. quite a few customers were convinced to order 360/67 (very similar to 360/65 but with the addition of virtual memory) to run with tss/360. http://en.wikipedia.org/wiki/TSS/360 above has references to TSS/360 supporting position independent code. while tss/360 had lots of novel new stuff ... it never quite reached production quality ... so almost all customers run it with something else. lots of them just used it as 360/65 running os/360. however, the science center http://www.garlic.com/~lynn/subtopic.html#545tech ported cp40 to it for cp67 ... cp40 had originally been done on 360/40 with special hardware modification to support virtual memory http://www.garlic.com/~lynn/cp40seas1982.txt Unif of Mich ... did MTS ... later migrated to 370 (and some number of other univ. ran) http://en.wikipedia.org/wiki/Michigan_Terminal_System Stanford did Orvyl (where Wylburiginates). http://en.wikipedia.org/wiki/ORVYL_and_WYLBUR Boeing Huntsville got a 360/67 duplex which they ran with two separate systems with os/360.

A quick review of the z/OS components involved here: - The Hardware Configuration Definition (HCD) component of z/OS is part of the z/OS Base feature and runs in every z/OS LPAR. - The Hardware Configuration Manager (HCM) optional priced feature of z/OS is a PC-based client/server interface to HCD. The licensing rule is: HCM only needs to be licensed once for each PC that the customer wants to run HCM upon. Technically this would mean HCM only needs to be licensed once per customer enterprise, but as a practical matter it is probably more likely to be licensed once per customer location (which is typically represented by one customer number). -- David J.

Re: Find member in Linklist through JCL?
Bill, EXEC PGM=whatever without any STEPLIB or JOBLIB will give you a clue that it is or is not (S806) in the link list. But it won't tell you which library. If you have access to PARMLIB and are able to compile a list of the libraries in the link list, then you may be able to use a quick and dirty utility program I developed years ago. PROGBLDL gets a list of program names (DDNAME=PROGLIST) and for each name issues a BLDL macro call to get the load modules directory entry. This information is written to output files PROGDATA and PROGSUMM. I think PROGDATA is the full DE and PROGSUMM is some portion. The BLDL macro searches DDNAME=DFHRPL for the program name in question. I think there is a byte within the DE that is the relative number of the library in the DFHRPL concatenation.

Hello, I was given the task of applying maintenance to z/OS 1.13 using a documented procedure and all was going well, however, some of the PTFs did not apply because I was not a super user UID(0). So, I had the guy who usually does the applies submit the job and this applied the remaining PTFs. However, when I was looking at some of the JAVA files, I now notice that the owner is now my UID: File owner . . . . . : (3011) Group owner . . . . . : TECH(9) Where before the owner and group was: File owner . . . . . : HZSPROC(0) Group owner . . . . . : OMVSGRP(1) There are likely other files from other PTFs where I am now the owner. Is this going to cause a problem running the system. Do I need to fix this?

Foklore is that possibly only 2-3 trivial sequences of code were found that could be considered similar. I don't have any recollection of RASP in OS/VS1 JES. I do remember talking to the JES2 group about enhancing shared spool. There were a huge amount of enhancements to VM370 for the internal world-wide sales&marketing support HONE system (very little shipping to customers before corporate hdqtrs was constantly trying to kill off vm370) ... some past posts http://www.garlic.com/~lynn/subtopic.html#hone part of this was cluster, single-system-image system ... at one time the US HONE datacenter in silicon valley had the largest single-system-image operation in the world, load balancing and fall-over/recovery across all the machines in the complex. The closest thing that came to it was ACP/TPF loosely-coupled operation ... but at the time ACP/TPF didn't have tightly-coupled support ... while VM370 had SMP support ... so could have max. loosely-coupled configuration of max. sized tightly coupled CECs. Standard OS/360 and ACP/TPF had started out using shared device reserve CCW, then do the I/O channel program, then do device release CCW. ACP/TPF got a special RPQ for 3830 disk controller "logical locking" ... that used memory in the 3830 allowing definition of logical locks ... for serializing logical operations w/o going through the overhead device reserve/release. The problem cropped up tho with string-switch architecture where multiple different 3830s had concurrent access to the same disk, lock memory in one 3830 would be consistent with lock memory in another 3830 for the same logical operation. The HONE system for loosely-coupled shared disk operation used a CKD "compare-and-swap" CCW sequence (one of the rare cases where CKD actually proved some benefit over FBA). Data was read from disk, updated in memory ... and a "search data equal" CCW (aka compare) was used ... if it didn't match, it failed ... however if it succeeded it would do a write operation. Note: later in the early 80s, HONE extended its cluster SSI across geographically separated datacenters, with a 2nd datacenter in Dallas and then a 3rd datacenter in Boulder. Had some meetings with people from JES2 group about enhancing JES2 shared spool to also utilize compare-and-swap CCW sequence. other trivia, Charlie had invented compare-and-swap instruction when he was working on fine grain multiprocessor locking for cp67 at the science cneter (mnemonic chosen because CAS are his initials). Attempts to get it into 370 architecture were initially rebuffed because the POK favorite son operating system people claimed that test&set was sufficient. Challenge was in order to get compare-and-swap into 370, had to come up with non-multiprocessor uses (examples still are included in principles of operation). some past posts http://www.garlic.com/~lynn/subtopic.html#smp past posts mentioning aspen (clone vendor's name for rasp): http://www.garlic.com/~lynn/2000f.html#69 TSS ancient history, was X86 ultimate CISC? designs) http://www.garlic.com/~lynn/2001g.html#35 Did AT&T offer Unix to Digital Equipment in the 70s? http://www.garlic.com/~lynn/2002i.html#63 Hercules and System/390 - do we need it? http://www.garlic.com/~lynn/2004q.html#37 A Glimpse into PC Development Philosophy http://www.garlic.com/~lynn/2005p.html#44 hasp, jes, rasp, aspen, gold http://www.garlic.com/~lynn/2005q.html#26 What ever happened to Tandem and NonStop OS ? http://www.garlic.com/~lynn/2005q.html#27 What ever happened to Tandem and NonStop OS ? http://www.garlic.com/~lynn/2006f.html#26 Old PCs--environmental hazard http://www.garlic.com/~lynn/2006w.html#24 IBM sues maker of Intel-based Mainframe clones http://www.garlic.com/~lynn/2006w.html#28 IBM sues maker of Intel-based Mainframe clones http://www.garlic.com/~lynn/2007m.html#69 Operating systems are old and busted http://www.garlic.com/~lynn/2010i.html#44 someone smarter than Dave Cutler -- virtualization experience starting Jan1968, online at home since Mar1970 -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO
