Re: POSTing a WAIT in another Address Space; POST ASCB= parameter; S602 Abend
A mea culpa from me since I started this thread: POST with the ASCB parameter indeed works. ASCB requires, as documented, the address of the ASCB. And the parameter supports RX (LA instruction) or register specification (LR) to accomplish this. By using the RX specification (LA), what I was providing was the address of the address of the ASCB, rather than the address of the ASCB itself, thus the S602 Abend. And I claimed on September 4 that RX had no use: "I don't see how LA of anything would work, yet the macro supports it." Well, RX works, and can be used when the ASCB is within, for example, the caller's own addressability. What I had was already the address of the ASCB in the target address space, not the POSTer's address space. So, the register notation LR was required in my case, but the RX (LA) specification is helpful for other ASCBs. So, my apologies, IBM documentation!

Re: POSTing a WAIT in another Address Space; POST ASCB= parameter; S602 Abend
Use of CS for what we call "quick post" works only if the ECB is in common storage and if the ECB is not yet waiting. You still have to be fully prepared for it to be waiting and code to use IEAMSXMP (or cross memory POST) when you encounter that. It is generally not all that common to find that the ECB is not waiting, but it certainly does happen. We rarely find it worth the extra code and usually waste the cycles trying the CS. The documentation for macros such as IEAMSXMP is intended to be clear about the level of indirection for your parameter. I'd hope any programmer would be able to get the ECB specification right with documentation such as: ECB=xecb is the name (RS-type), or address in register (2)-(12), of a required fullword input which is the ECB to post. So if you specify a "name", it is the field name of the ECB (it's up to you to have provided addressability). You'll see that the expansion takes the address of what you specify. If you specify "address in register", then you have provided the address of the ECB. You'll see that the expansion takes the contents of the register. The documentation for older macros such as POST is weak in that regard. Contrast the ECB=xecb documentation above with the doc for the ECB positional parameter of POST: ecb addr ecb addr: RX-type address, or register (2)-(12), except (10). -and- ecb addr Specifies the address of the fullword event control block representing the event. Do you specify the ECB itself? Do you specify a word containing the ECB address? What do you put into the register if using register form? This problem is pervasive. Since it's unlikely that this pervasive problem will be fixed in the broad sense (an individual case will be addressed if complained about, I'd think), you should be in the habit of looking at the expansion and giving a modicum of thought to what is going on. Clearly a service that is going to update an ECB needs, on input, the address of the ECB, not its contents. If the register form is going to have the address of the ECB, then the expansion for non-register will take the address of what you specify and pass that. So if you specify the ECB itself, such as ECB=MYECB, you'll get the address of MYECB passed, and you'll be good. If you specify something that contains the address, such as ECB=ADDRESS_OF_MYECB, you'll get the address of ADDRESS_OF_MYECB. Things won't go well.

Re: POSTing a WAIT in another Address Space; POST ASCB= parameter; S602 Abend
Richard, Please avoid RUCSA for new development at all costs. User-key common storage is a huge security/integrity exposure to the system. RUCSA was implemented to provide relief to customers that rely on software that still uses user-key CSA where updating the code was impossible (maybe lost) or extremely difficult and they needed more time to migrate to alternative solutions. Depending on what you need to achieve there are some really nifty XCF services that can enable inter-address space communication, with the added benefit of possible sysplex-wide scope. For example, take a look at IXCSEND and IXCRECV services - I know of a few ISV products that have replaced a lot of PC-ss style code with these services.

Thanks, Rob, Tom. Yes, Key 0 is dangerous, but documented as a requirement (for LINKAGE=BRANCH anyway). I was unaware of IEAMSXMP (and TCBTOKEN, which extracts the target program's TTOKEN). So I'm coding for those now. BTW, the standard from of POST supports register notation and RX-type. Rx does a LA - ST into the POST's parameter list, which means it's the address of the ASCB, not the ASCB itself. I'll try L Rx,ASCB and POST . . . ASCB=(Rx) and test that.

Re: POSTing a WAIT in another Address Space; POST ASCB= parameter; S602 Abend
I agree with Tom - naked XM POST in Key0 makes my eye twitch nervously. I am not in the office, so cannot check myself, but take a look at the expansion in the listing to see how the ASCB keyword is treated. Maybe try loading the ASCBtokn into a reg and then code ASCB=(Rn)?

POSTing a WAIT in another Address Space; POST ASCB= parameter; S602 Abend
Trying to POST a WAIT ECB in a different address space. I'm getting a 602 abend: "The target address space control block (ASCB) is incorrect."

Here's the scenario: 1) Started task A creates a name-token pair containing its ASCB and ECB addresses (IEANTCR data sharing) 2) Started task A then WAITs on the ECB 3) Job B is started and retrieves the name-token pair (IEANTRT) 4) Job B MODESETs to supervisor, key zero 5) Job B issues a POST: POST ECBtokn, ECB address from Token (Name-Token pair) + ASCB=ASCBtokn, ASCB from Token (Name-Token pair) + ERRET=PostErrR, + LINKAGE=BRANCH, + ECBKEY=0 ASCBtokn DSA ASCB of started task address space ECBtokn DSA address of ECB in started task 6) Job B abends w/602: "The target address space control block (ASCB) is incorrect." LINKAGE=SVC and LINKAGE=SYSTEM were tried and returned the same abend. Also, the List and Execute macro forms of POST were tried with the same 602 result.

Re: Spawned address space name quandry
Mark See "z/OS UNIX System Services Programming: Assembler Callable Services SA23-2281-60" The BPX1SPN/BPX4SPN service describes the jobname of the spawned address space as follows in item 3 of the usage notes. "The job name of the parent is propagated to the child and appended with a numeric value in the range of 1–9, if the job name is 7 characters or less. If the job name is 8 characters, the job name is propagated as is. When a job name is appended with a numeric value, the count wraps back to 1 when it exceeds 9." Are you saying that these rules are not followed? Your description seems to be at odds with the documented rules. However, I see under item 28 of the usage notes the following. " The _BPX_JOBNAME environment variable can be used to change the job name of the new process image. The job name change is allowed only if the invoker has appropriate privileges (see Authorization). If these conditions are not met, the environment variable is ignored. Accepted values are strings of 1–8 alphanumeric characters. Incorrect specifications are ignored. A job name can be specified in the INHE structure. If both the INHE JOBNAME and environment variable _BPX_JOBNAME are specified, the value in the INHE structure is used. If _BPX_JOBNAME is specified and _BPX_SHAREAS is set to YES, then _BPX_JOBNAME is ignored." Maybe you have that environment variable set.

Re: SDWARTYA in different address space
wonder if SETRP can retry in different address space the doc says you can run it in AR mode Whether you can issue SETRP in AR mode has nothing to do with "retry in different address space". The space from which data is fetched by SETRP (which in your example is "nothing" because you specified register form) is not related to the address space in which you retry (which itself is an inaccurate-enough term to be not useful). The cross memory environment for any recovery routine's retry is well-defined and depends on what you have chosen to identify. One additional tidbit is bit SDWARFXM (which applies to FRRs only). Its comment is correct. So if RETADDR=(RX) and access RX has an ALET ? Whether or not you can invoke a macro in AR mode is not sufficient to know if the data can be in a data space. These questions can often be answered simply by looking at the expansion. What do you get for the retaddr processing of SETRP RC=4,RETADDR=(RX)? You get "LR15,RX" then "ST15,SDWARTYA-SDWA(,1)". And you get that whether or not you have SYSSTATE ASCENV=AR. Thus it is irrelevant what is the ALET in Access register RX.

catalog address space autotune
Hi list, Curiosity question more than anything. I saw an old post from Lizette talking about migrating from z/OS 1.4 to 1.7 and noticing that CAS autotune was now active. Yet I'm running 2.4, and seeing that autotune is disabled and the manual says it cannot be enabled. That leads me to a couple questions. Obviously IBM shut off the ability to do autotuning for a reason. Any educated guess as to whether or when IBM may revisit this and get it working? Most of my large catalogs have a CAS cache hit ratio of well under 10%. Looking at a couple catalogs I see that I have default (read very few) data or index buffers. Would I be better off increasing the number of buffers for my heavily hit catalogs or should I add these catalogs to VLF?

Re: ZFS Address Space, shared ENQ but filesystem isn't mounted
Perhaps see if the zfsadmin fsinfo commands reveal anything that might give a clue: https://www.ibm.com/docs/en/zos/2.4.0?topic=commands-zfsadm-fsinfo e.g. any shrink/salvage operations in progress, is it quiesced, what is the status, any connected clients.

Re: ZFS Address Space, shared ENQ but filesystem isn't mounted
Is this filesystem a shared filesystem? Perhaps it’s mounted on another LPAR in the plex. Apologies if this has been asked before. You could always do RO *ALL,D OMVS,F,N=name to verify.

Address space creation time for TSO user
I'm after a reliable field that will tell me the time at which the address space was created for a TSO user. More specifically, I need a time which occurs between the user issuing the logon request and the logon screen being sent to prompt for a password. I've been used to reaching for ASCBINTS but that doesn't seem to be touched until after the password has been filled-in and the user has hit enter.

Re: Currently executing TCB in an address space
If you're running authorized then you can get into Supervisor mode and serialize, but that still won't let you query an address space that is swapped out. For his purposes that may not matter, since if it is swapped out then it doesn't have a TCB on any CPU. -- Shmuel (Seymour J.)

Re: Currently executing TCB in a address space
I'm rusty, but my understanding from MVS/ESA days is that PSATOLD is always set as the current task becomes active, and there is one PSA for each 'engine', so by definition if your code is running under a TCB, it always gets its own TCB address from that field. Also, I haven't seen a TCB virtual address change (except where the task is terminated for some reason, and the same code is restarted under a fresh TCB, of course, but that doesn't count) Please shoot me down if this has changed, naturally :-) If the question is for code running in a different AS to find the current TCB in a target AS, that's a lot more complicated :-) Roops On Sat., May 15, 2021, 13:24 Peter Relson, wrote: > What task am I running under?

Querying WLM address space CPU delays
We have an in-house tool that monitors CPU consumption and other performance metrics for address spaces and CICS transactions. This data is summarized every 5 minutes to allow easy querying and comparisons. All of this data is stored in DB2 and we have created some impressive SQL queries to quickly and efficiently display anomalies and critical issues. Our management runs our mainframe near full capacity to achieve "full value" for their processors. Needless to say, we don't always have enough tolerance to allow CPU consumer "outliers". With this tool, researching high CPU consumers that are out of their average have become easy, but we cannot easily determine the perceived impact. Just because an address space is consuming more CPU and the system is at 100% doesn't necessarily mean our customers are perceiving any negative impact. The system could be over its CPU share for the sysplex and another system may have spare CPU to 'steal'. Having the ability to see any delays in our lower service class address spaces would be a great addition. I've been working on a major enhancement to collect CPU delays (I really don't care about other types of delays at the moment) for each address space, but I'm not getting the desired results. I read that IWMRQRY and IWMCOLL appear to be the best services for this solution. However, I found that neither of these services return an ASID or any identifier of an address space. IWMRQRY has an input parameter for ASID, but running this service for every active ASID on the system (roughly 150 on our sandbox system) every quarter second (our WLM interval) is not cheap. Is there a better solution for collecting this data or am I missing something about these WLM services?

Re: What were the first models to support Dual Address Space?
My fist job in the summer of 1982 used a 4341 group 1 that ran MVS/SP 1.3. It did have the Console and PC/AUTH address spaces. Been nearly 40 years ago.

Re: What were the first models to support Dual Address Space?
The 4341 was introduced in 1979 before DAS (1981), and was marketed primarily for its ability to run in ECPS:VSE mode to support DOS/VSE. GA24-3672-4_4341ProcessorMG1FunctionalCharacteristics under Programming Support says"programming support is provided by DOS/VSE, OS/VSl, OS/VS2-MVS, and VM/370". That doesn't preclude the possibility of adding DAS support later, and in fact the top of the 4341 line model group 12, introduced near the end of 1982, apparently did include DAS support as a standard feature (Ref: GC20-2102-2 Guide to the IBM 4381 Processor, p128, comparing features of a 4341 MG12 to features on 4381 models). Availability on at least one model is sufficient to demonstrate DAS support existence on a 4341. Joel C Ewing On 1/8/21 12:35 PM, Seymour J Metz wrote: > Thanks.

Re: What were the first models to support Dual Address Space?
Apresentation at SHARE 118 (March 2012) by Dan Greiner, http://comet.lehman.cuny.edu/cocchi/CMP464Mainframe/2.0ZArchitectureLectures/IBMDualAddressSpace.pdf indicates that Dual address space (DAS) support feature was added to the S/370 architecture in 1981. Based on introduction year, thelikely candidates for being first machine with DAS support include later models of 3033, 4381, 3081, 3083, and 3084. Functional Characteristics of 3084 indicates it has Dual-address space (DAS) as a standard feature, but also lists it as a "3033 extension:" That name seems to confirm that some model of the 3033 was the first with DAS. The introduction year 1981 would explain why a 1979 3033 manual wouldn't mention it. The MVS/SP Release 3 Installation Considerations (July 1981) manual referenced by wmhblair, doesn't mention Dual Address Space support by that name but does describe "3033 Extensions" as an optional microcode feature to support Cross Memory Services in MVS/SP R3in a VM environment. That optional feature was available for 3033 Models A, N, S, U, and M -- not a standard feature, but the 3033 was the first machine for which it was available.

Re: What were the first models to support Dual Address Space?
I believe there also was a hardware assist for the 4341. I think that the 4381 had it. I have some recollection about the 370/168 but it may have been supported by the PROGFLIH. I remember that SP1.3 was as slow as molasses on the test system at Western Electric.
