The ENF listener requires use of CSA storage. When the Started Task receives an operator command to start SMF interval processing it allocates CSA storage, registers the ENF listener, and WAITs for interval expiration. The question is: what should it do when the operator command says to stop SMF interval processing? The options seem to be: 1) Deregister the ENF listener and free the CSA storage, meaning an operator can switch SMF interval processing on and off, causing CSA storage to be allocated and deallocated, possibly fragmenting CSA storage. But when we aren't collecting SMF interval data, we won't have an ENF listener registered. 2) Leave the ENF listener registered, but stop writing records when the interval expires. Don't stop the ENF listener and free CSA until the Started Task terminates (or possibly a special operator command like /f stcname,SMF STOP). This approach is easier on CSA allocations for the case where the operator is switching SMF interval collection on and off. But it leaves an ENF listener registered when one is not needed.

Re: Cell pool questions
Charles You could solve this requirement using a code solution - for example : (1) Design a common structure for a cell pool identifier - something that includes the cell pool id and some double-word count fields for GET and FREE operations (2) Build a macro to front-end the CPOOL GET and CPOOL FREE services (eg #CPOOL GET and #CPOOL FREE) that take a pointer to the structure in (1) as a parameter (3) Inside the macro, issue the real CPOOL GETs and FREEs - however you can now maintain the GET and FREE count fields using CSG (4) Write your own service to list/dump the contents of the structures in (1) for diagnostic purposes Obviously the above is simplistic and you could get into a more elegant solution depending on the environment that you are working in. If the program is running in a server, then perhaps you could consider a separate TCB acting as a storage manager (SM) and all other TCBs having some sort of API to GET and FREE cells from within defined pools. If so, the SM TCB could use callable cell pool services to manage the pools and the APIs could just manage your own free cell queue(s). The big advantage of callable cell pool services is the ability to contract the pools if required. Rob Scott Lead Developer Rocket Software 77 Fourth Avenue . Suite 100 . Waltham . MA 02451-1468 .

Okay, moving right along ... re-formulating the question: Is there any way to determine the number of cells in a CPOOL cell pool? I have a cell pool with a primary and a secondary count. It occurs to me that if, for example, I had a bug in which one time in ten I failed to return a cell to the pool, that I would have no indication of a problem until I got an SC78 abend, which might take quite a while. I am kind of inferring that I could do a LIST and get the number of extents from work area Word 3 (possibly iteratively based on Word 1), from which I guess I could determine the pool size as primary + (secondary * (extents - 1)). Is that correct? Or is there not a one-to-one between pool expansions and extents? Is there a better way? Actually, I now see that that method won't work very well because I have no way of making sure that there would be no intervening GET requests. The GET requests come from asynchronous processes which the main task has no ability to pause. I guess I could just make sure the work area was large enough to get all of the extents in a single call?

Re: CSVDYNEX ?'s
If your dynamic exit has its own recovery routine and it recovers successfully, the the abend count will not be incremented and CSV430I will be avoided. There is no documented ENF signal for any CSVDYNEX service. You have at least the following choices for notification of possible problems with your exit : (o) Periodically issue the LIST request to check on the exit status (o) Make your dynamic exit update a count field or STCK value somewhere every time it is invoked. (o) If you have a recovery routine for the exit, you could provide your own notification service to your server address space when it is invoked for an abend in the exit.

Re: How to? Receive response to a z/OS command issued by a program
Yes - the accepted way to do this is to use EMCS consoles. A few gotcha's waiting for you in the darkness : (1) Name your EMCS console carefully - beware that other consoles active in the sysplex using the same name can generate confusion and extra return and reason codes to handle (2) To get a response, use the CART keyword on the MGCRE - however, note that not all operator commands respond using the CART (it depends on the software that gets control to generate the response). (3) To handle (2), I would advise some sort of timer to pop after nn seconds and give up waiting for a response. I think the data shown by SDSF on the LOG command (not opercmd responses) is gotten via spool browse services (or OPERLOG) rather than an EMCS with unsolicited messages.

1)If your authorized program while executing in PSW key 0-7 stores into an address provided by an unauthorized caller then this is a violation of the IBM statement of integrity.

Re: Program FLIH backdoor - This is a criminal breach of security!
How about : If your authorized program, while executing in PSW key 0-7 stores into an address provided by an unauthorized caller without using the caller's key then this is a violation of the IBM statement of integrity I am sure there are other people on IBM-Main who could make this more readable and accurate. Truth is that there are lots programs out there (public domain, in-house utilities) that just splat into caller storage using Key0 regardless of caller key. A good example of how to do it properly in Authorized Assembler Programming Guide would be my preferred start for re-education of the masses.

Re: LAE instruction
Note also that using ALESERV ADD for ASSBSTKN using CHKEAX=NO for a foreign address space (ie not under control of the primary ASID where you code is running) is NOT recommended. If the other ASID *is* under control of your PASN there is a good chance that ASCRE was used to start it earlier in your code, in which case you will have been handed the STOKEN in the ODA return area and can use SASN mode to access its private storage. If the ASID is truly foreign then the best way to access its private storage is to use SRB mode programming - search the archives as this has been discussed in the past.

Re: LAE instruction
Micheal, Putting a bit of meat on the bones to create an example piece of code with comments and notes : (o) We are going to process a linked list of FOO elements in a dataspace and calculate some random hash value based on a subset of bytes in the FOO_NAME field. (o) This code has been just typed into my e-mail - they may be typos/errors (o) WA is the working storage structure/DSECT DO, ALESERV ADD,STOKEN=WA_FOO_STOKEN, Add dataspace containing linked list of FOOs ALET=WA_FOO_ALET, AL=WORKUNIT, MF=(E,WA_ALESERV_LIST) DOEXIT (LTR,R15,R15,NZ) Failed - quick exit SAC 512 AR-Mode (1) SYSSTATE ASCENV=AR Inform assembler of AR-mode L R6,WA_FOO_HEAD Get head of list LAM AR6,AR6,WA_FOO_ALET Get dataspace ALET (2) USING FOO,R6 DO UNTIL=(ICM,R6,B'',FOO_NEXT,Z)Traverse list (3) LAE R7,FOO_NAME Point to FOO_NAME (4) LAE R1,8(,R7) Use R1 for temp pointer (5) XC WA_HASH,WA_HASH Zero hash value DO FROM=(R14,=AL4(L'FOO_NAME-8)) XR R0,R0 IC R0,0(,R1) Get 1-byte (6) AL R0,WA_HASH Add to hash value ST R0,WA_HASH Store new value LAE R1,1(,R1) Next byte of name (6) ENDDO NC WA_HASH,=X'00FF'0-255 range for hash ENDDO SAC 0 Inform assembler (7) SYSSTATE ASCENV=P ENDDO (8) rest of code (9) Notes : (1) I think it is always worth having a macro to do both the SAC and the SYSSTATE for you in one hit (not shown)- stops you forgetting the SYSSTATE and that can confuse any macros that follow. (2) Loading the ALET in to the AR for the first time - R6 will be able to address data in the dataspace (3) AR-mode makes traversing data structures in dataspaces easy as you can just use normal instructions (if you play by the rules) (4) Because LAE used and FOO dsect covers R6+AR6 - AR7 will contain ALET for dataspace after instruction executed (5) This time we are using R1 to point at 8 bytes into FOO_NAME (for whatever reason) - note that AR1 will get the dataspace ALET (6) Loading and using a byte from the dataspace (7) See (1) (8) Assuming all ARs are zero before we start, if the code goes thru successfully, then AR1, AR6 and AR7 will contain the ALET of the dataspace here - you may wish to consider zeroing the ARs at this point if they are no longer needed. (9) Prudent use of LAM AR14,AR1,=4A(0) will protect you from unintentional AR values in working regs after calling certain system services - you can never be sure how in-house macros expand.

Re: Processor usage
If you are not going to use SMF-70 records, you could consider using the ERBSMFI programming service (see the RMF manual) as part of the information returned by this API includes the system CPU% busy (from MVS perspective rather than LPAR view IIRC) and page rate. Note also that CMF provides an alias to this program as well so that any code you author for ERBSMFI should work all systems. If this does not suit your requirements - then I think you are going to have to roll your own solution. What exactly are you trying to achieve? CPU utilization figures over very small intervals are next to meaningless on their own (in my opinion) and even sustained high CPU% over long periods could be OK as long as the WLM goals are being met.

Performing security checks in the stub (which runs unauthorized, and can be bypassed) are not really effective. If security checks are needed, they should be in the authorized program that is invoked by IKJEFTSR (your auth function module). Also, if the REXX exec merely needs to call an authorized assembler routine (not subroutine) then a simple address TSO call *(modulename) may be simpler.

Is there any straightforward way to convert an STCK value from some point in the fairly recent (months, not decades) past to local time for the LPAR's locale? By straightforward I mean without having to maintain my own table of time changes for the historic period? I know about CVTLDTO (and CVTLSO). They can be used to convert a current STCK value to local time. But what about a time that might be hours, days, or months in the past? (Of course, a nanosecond after you do an STCK it's a historic value, so the problem always exists, but at least the window there is fairly small.) For that matter, the same problem exists for leap seconds, but at least there the variance is small and the historic changes straightforward. (And No, I am not interested in revisiting the what about an STCK right at the leap second moment thread from 2009.) Why? Several types of data in z/OS have timestamps in raw STCK form, and some customers want dates and times reported in a culturally comfortable format. Environment is z/OS batch; language is XL C++. Correct me if I am wrong: it appears to me that gmtime() converts *to* GMT but localtime() assumes the time is already local. Converting *to* gmtime is a tougher problem because 1:30 am on the morning that we fall back to standard time is an ambiguous specification, is it not?

Re: Calling all experts on SMFPRMxx SUBSYS - How does Subsys of SILO work?
Martin, I have seen this at various sites as well, and thought that it was just the vendor's way of writing the user SMF records for tape silo performance. For example, you can use : SMFEWTM (Rx),SUBSYS==CL4'SILO',. Maybe originally there was some other compelling reason for this - (maybe they used the SUBPARM facility?) or maybe it was just a way of forcing all SMF records for the tape silo to one place. However, if there is NOTYPE(0:255) it seems sort of self-defeating.

Anyone know anything about the subsystem? For some reason they have excluded SMF records with that subsys. I see two problems/questions: 1) Getting address space counts out of RMF Type 70 Address Space Count section. They're there for TSO, STC etc but not for user-defined. I assume subtracting some of these from headline number would give (usually 0) user subsys address space count. 2) Wondering how WLM allows you to classify work from such a user subsystem. e.g. What qualifiers?

OK, I gotta ask -- what's the problem you're trying to solve? You don't trust your customers? In over a quarter century in the mainframe software business, I've come across ONE customer running software on an unlicensed box, and it was an oversight -- and a nice full-price bluebird for the sales rep. I don't believe CPUIDs are worth the hassle. Having said that, I would expect that any CPUID processing would work off, well, the CPUID. That's what customers understand. SAS Institute used to have a nice CPUID system for their C compiler that would issue a warning and print out what company the sucker was licensed to, but would continue to operate if the CPUID was wrong. This allowed emergency operation, while clearly keeping any real company from running it on the wrong box (though I suppose of BigBox, Inc. licensed it on one and ran it on two, it would be harder to notice; the case I'm thinking of was when we were running the Merrill-Lynch copy on another company's machine, WITH permission from SAS; every time we invoked the compiler, it would whine and say Licensed to Merrill-Lynch). Now, with systems management stuff that doesn't have a real UI that gets invoked all the time, it's harder. The best I've seen allowed: - multiple key entries in the CPUID file, so you didn't have to worry about swapping files at expiration: you just added new entries and eventually deleted the old ones. And you could keep all your CPUIDs in a common file, shared (or replicated) across systems. - Warned starting 30 days before expiration, on the operator's console: XYZ will expire in 30 days (29, 28...). - If it had a valid license (i.e., one with time on it but on the wrong machine) would run in emergency mode, whining on the operator's console every 10 minutes or so, but still running (this allowed for DR). - Supported universal temporary keys, that could be read/emailed/FAXed by support at 3AM if you really screwed up and were dead in the water despite the above. Now, this also meant that there were folks carrying beepers and temp keys, so they could do that after-hours support. Are you prepared to deal with all this? Is it worth it?

Dec 15, 2011 THE OPEN MACRO SUPPORTS ONLY ASCENV=P. But there is NO NEED to ASM a new load module under 1.13; your currently executing MXGTMNT module works just fine! -This IBM note (migration guide) is the ONLY clue of the incompatible change, which impacts OPEN/CLOSE macros, but doesn't mention any by name: DFSMSdfp: Accommodate 64-bit AR mode rules enforcement in DFSMS macros; required if you have code that invokes DFSMS macros (but not all!). Before z/OS V1R13, many DFSMS macros that did not support 64-bit or AR mode did not react to being invoked in 64-bit or AR mode, and generated code that might have been invalid in 64-bit or AR mode. Starting with z/OS V1R13, these macros are changed to issue an assembly-time message and suppress expansion if they are invoked in 64-bit or AR mode. -But as noted above, you didn't really need to ASM. Now, from MXG's asmguy, his comments on this change: Nothing is going to happen to an existing site using MXGTMNT and in fact the modification I have to make for this does not result in any change to the executable code. The SYSSTATE macro is an assembler directive - it sets a flag that tells any macros that support AR mode (Access Register, used for cross memory access) to use their AR mode compatible expansion. Macros that don't have an AR mode expansion used to ignore this because they had nothing to do, and it's always the coder's responsibility to make sure that when those non-AR compatible macros are executed, that the system is not in AR mode. This is similar to switching back and forth from 24-bit to 31-bit mode: some macros can't tolerate 31-bit mode. Nothing has really changed though; it is still the coders responsibility to make sure the system is not in AR mode and macros that can't tolerate AR mode still can't, except now IBM is requiring the coder to explicitly set SYSSTATE to indicate to the assembler that the system is not in AR mode. Of course this is all very silly because the assembler can't know ahead of time that the system is or isn't in AR mode. So regardless of whether or not SYSSTATE is coded this way the system still could be in AR mode, OPEN/CLOSE will still expand the same way, and if the system really is in AR mode OPEN/CLOSE will abend when executed. So the bottom line is that nothing has changed except our need to do something for no reason at all. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN

Re: S402 ABEND upon cross-memory POST
Justin, May I politely suggest that you have another look at the design - you have at least three storage keys involved in this scenario I would feel uncomfortable with a solution that X-memory POSTs a Key-7 ECB using ECBKEY=0 and involves an EVENTS table in Key-8. Key-7 CSA hints that this might be a DB2-related program - is there any reason why your EVENTS table owner cannot execute in Key-7 and then remove your Key-0 and Key-8 usage altogether?

Re: Hiperspaces
Hiperspaces are typically used when you are dealing in chunks of 4K pages - I think dataspaces would be more suitable if you insist on an AR-Mode solution as it allows direct byte access. However, there are a few alternatives to consider here : (1) Shared memory objects (2) PC-ss to add SYSPRINT data to target ASID private? (3) IARVSERV I am sure others in this list will point out other choices Rob Scott Lead Developer Rocket Software 275 Grove Street · Newton, MA 02466-2272 · USA Tel: +1.617.614.2305 Email: rsc...@rs.com Web: www.rocketsoftware.com -Original Message- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@bama.ua.edu] On Behalf Of Scott Ford Sent: 11 November 2011 16:03 To: IBM-MAIN@bama.ua.edu Subject: Hiperspaces All: Has anyone used Hiperspaces via Assmelber ?

Re: How to enable Storage Protection Override?

Re: FORCE ARM
FORCE ARM is pretty much just an standard MVS CANCEL that has been prefixed by some bit-twiddling (or bit-ignoring) to enable CANCEL to work against address spaces that are marked non-cancel , and task-level recovery routines and task-level resource managers for the ASID receive control as usual. FORCE *without* ARM results internally to CALLRTM TYPE=MEMTERM which will bypass task-level recovery routines and resource managers (whilst still allowing address space level resource manager to get control). Bearing all this in mind, I have always believed that ARM stood for Allow Recovery Management or Allow Resource Managers. I think it is just a happy coincidence or developer humour that forcing someone's arm is a saying in English.

Re: ENF (event notification facility) question
Listening on ENF codes is a very common thing to do and you will find that RMF and ISV monitors do this sort of thing a lot. If you are coding the routine that gets invoked when the ENF code occurs, you need to be fully aware of the environment in which you get invoked - for example : you may get invoked in SRB mode. My general advice here is to not try and do anything too clever in the ENF exit routine but just store away the bits of data you are interested in and notify your server address space to process asynchronously - maybe by some sort of event/request block on a queue or updating some counter somewhere.

Personally, I think SETLOCK is overkill for what you are attempting to do. Either a circular buffer or a slotted (pre-divided) buffer can be maintained in some sort of common storage across multiple tasks and ASIDs using CDS (Compare Double and Swap).

Re: ISPF TLD control block lookup Z/OS 1.12 ISPF 6.1
That looks very similar to something written by Doug Nadel (IBMer in ISPF team) many moons ago. It comes with disclaimers about not being supported - however the logic has worked for many years. Since the REXX was originally written ISPF has been enhanced to return the screen image info in ISPF system variables ZSCREENI and ZSCREENC if requested - can you convert your code to use that instead?

Re: musings on listing a catalog
Fairly simple to achieve as a REXX external function in assembler by calling
IGGCSI00 and then IRXEXCOM to create the REXX variables.
There is some decent doc on how to code REXX external functions in the TSO/E
REXX Programming Services chapter in the TSO/E Rexx Reference manual and
there a quite a few samples out there in CBTtape-land.

OK. I've looked at IGGCSI00. Way to complicated, IMO. REXX

Isn't this how REXX deals with record/field data structures? :-)
I was thinking more how the SDSF REXX and UNIX REXX work. Not with blobs, but
with stem variables and predefined named constants. The environments are by
initialized by invoking an initialization routine (ISFCALLS or SYSCALLS). Gee,
for a LISTCAT, would it be CATCALLS? grin No, more likely IDCCALLS.
Example:
if 3 idccalls('on') then do
say Failed to set up catalog environment
exit 8
end
cluster='SOME.VSAM.CLUSTER.NAME'
address idcams listc ent((cluster)) (stem outrec.
if rc0 then say LISTC ended with a return code of rc if outrec.ENT_DSORG
KSDS then say Dataset:cluster is not a VSAM KSDS file!
say avgrec is word(outrec.ENT_RECORDSIZE,1) max lrecl is
word(outrec.ENT_RECORDSIZE,2) Say Volume are:
do i=1 to outrec.ENT_NUM_VOLUMES
say Volume i is outrec.ENT_VOLUME.i end
/* or maybe */
do i=1 to words(outrec.ENT_VOLUMES)
say Volume i is word(outrec.ENT_VOLUMES,i) end
Now, that is relatively simple.
Take a look at the JZOS wrapper for CSI; it handles decoding of
fields, but still requires an understanding of how CSI works -
http://www.ibm.com/developerworks/java/zos/javadoc/jzos/com/ib
m/jzos/CatalogSearch.html
http://www.ibm.com/developerworks/java/zos/javadoc/jzos/com/ib
m/jzos/CatalogSearch.Entry.html
http://www.ibm.com/developerworks/java/zos/javadoc/jzos/com/ib
m/jzos/CatalogSearchField.html
An interesting coding project would be to write a Java utility that
would
provide an XML interface to CSI, using this wrapper.
Perhaps we should
consider it as a future JZOS sample program.

Re: dynamic STEPLIB
Products that can be invoked under LIBDEF for ISPLLIB must be coded to recognize and support it - otherwise any bog-standard LOADs could be issued without awareness of the tasklib DCB requirements and you end up with an S806. If the product sticks to just ISPEXEC SELECT to invoke any other programs, then you are probably OK - however if there is a LOAD lurking in the code, then it must be handled correctly. ISPF has made this easier in recent years with the introduction of the QLIBDEF service so that a product can query the ISPLLIB and dynamically allocate its own tasklib to pass on the LOAD DCB keyword. I would suggest that if you have an IBM product whose ISPF interface does not support LIBDEF for ISPLLIB, then consider raising this as a PMR/ETR.

Re: What is the current feeling for MVC loop vs. MVCL?
I am going to digress a bit here. I got into a discussion with Martin Packer about some of this and it raised a few interesting thoughts : (1) What percentage of executed MVCL instructions are for clearing storage versus actually moving data? I know that in the software I am involved in, that MVCL(*) for clearing is used *way* more than any movement purposes as I am a heavy user of CPOOL services. Obviously you can have fast clear for objects with lengths that 256-multiple using n*XC - however I have often wished for a ZERO=YES option on the CPOOL BUILD so that you are guaranteed a clean cell for each subsequent CPOOL GET. If anyone else agrees, I might consider raising a Share requirement (2) Is there any performance difference in MVCL when L2 is zero? I seem to recall hearing a while ago that there might be...however am not sure. (3) How does MVC v MVCL compare in AR mode with source and target using different ALETs ?

Re: What is the current feeling for MVC loop vs. MVCL?
One minor thing to remember that if you are dealing with lengths that are not a multiple of 256 bytes, then the MVC loop method is going to have to drop thru to an executed move for those remaining bytes. This means that you need addressability to that target of the execute instruction and depending on the environment where your code is executing that might be a non-trivial or non-desirable exercise. Dropping through to an actual MVCL to move those last remaining bytes might be a way to avoid the EXRx,MOVE_LAST_BIT :-) Rob Scott Lead Developer Rocket Software 275 Grove Street * Newton, MA 02466-2272 * USA Tel: +1.617.614.2305 Email: rsc...@rs.com Web: www.rocketsoftware.com -Original Message- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@bama.ua.edu] On Behalf Of Charles Mills Sent: 31 May 2011 23:24 To: IBM-MAIN@bama.ua.edu Subject: Re: What is the current feeling for MVC loop vs. MVCL?

The following is a snip from a program which I just ran on our Z10 whose characteristics are shown last below. The program first moved 65536 bytes from one location to another using MVCL and did this 1 million times. You'll see it took ~56 seconds. Then the same number of bytes were moved using 1 million MVC loops. This took ~8 seconds. Finally, the same number of bytes were moved 1 million times using MVCLE. I have run this program on every CEC that I have had available to me and the results are always relatively the same although the actual numbers change. MVCL has some extraordinarily useful functions: Truncation, padding and returning addresses and lengths after MVCL. Each of these would have to be done manually if a MVC loop were used and these instructions would have to be added into the total time for MVC loops. And, yes, I wrote a MVCL macro. But once one tries to support the case where bits 8 through 31 of R1+1 and R2+1 are not equal the macro gets very big and very awkward.

Re: SYMUPDTE Why is it not fully supported yet
Lizette I imagine that it is because its accidental miss-use could be confusing and possibly disastrous for the system. Certain software elements (IBM and ISV) will have been presented with data during initialization that has been translated from system symbols and they will be ignorant of the updated value unless specifically informed and that assumes that they have a service to dynamically update themselves where required. SYMUPDTE comes with caveats and if IBM were to officially endorse it then can you imagine the mess that users could get themselves into? How about the development resources (IBM and ISV) to change existing services to support the possible dynamic change of static system symbol?

No documentation of error messages or return codes. The most detail is in the 1999 Redbook SG24-5451 The object code is in SYS1.SAMPLIB. So each shop has to manually implement it.

An SVC routine easily can do that by manipulating control block fields. This conferrence leads directly to many of (or is itself) the system integrity issue(s) related to a magic SVC. I'm not convinced... I think the idea of the scary magic SVC is just something that's survived from decades past. They exist, of course, and I'm not minimizing the danger, but I don't see that it's much harder to code a magic PC routine to manipulate control block fields in an equally unsafe way. Ed Jaffe mentioned SVC screening Yes. And some of us have asked for PC screening for years. Curious: Does anyone use SVC screening for its documented intended purpose: to define those SVCs that a particular task is allowed to issue (and conversely those that it is not allowed to issue)? Hmmm... IIRC SVC screening was introduced in the late 1970s in support of VSPC (does anyone remember this product that was going to replace TSO as an end-user general purpose time sharing system, leaving expensive-to-run TSO only for sysprogs and the like? Anything to avoid users moving to CMS...) If SVC screening was intended only for disallowing certain SVCs, surely it would have a simple table of 256 yes/no bits. (Well, plus a couple more for ESR, perhaps, but still just a permissions table.) But instead, it has not just a table, but the ability to get control and do arbitrary things when a disallowed SVC is issued. So I'm not sure it was so simple as defining which SVCs a task can use. Surely VSPC did not just fail all disallowed SVCs, but converted some of them into different implementations to allow hosting of e.g. TSO apps in its non-TSO environment. We have used screening to deal with the case of a vendor product that in some cases issues TGET in a non-TSO environment. Unfortunately TGET returns RC=0 in such a case, and if the product assumes this means the (non existent) user has just hit enter, and re-issues the TGET... Well - it's not good for CPU consumption. We just change the RC to 8 (user has hit ATTN), and all is well. Whether this is what screening was intended for, I'm not sure, but I believe it's widely used for this kind of thing. I have encountered SVC screening in use by other vendors in production environments to modify GETMAIN and WTO arguments, among other things.

This was working fine until it came time to call the new subprogram from the main program, which does not need to be authorized. Making the whole process authorized seems silly (or worse), in addition to being inconvenient as there are many STEPLIB entries involved. I tried running the main program from an authorized LNKLST library, but quickly ran into S306-12 when trying to load a program from the STEPLIB. Is the best option to handle this setting up a separate region to handle the authorized calls and communicating via a PC? It looks like a PC client would have to be authorized, which defeats the purpose. How has this been solved in the past? Thanks for any suggestions and/or examples. APF is generally an all or nothing affair. z/OS, and MVS before it, was not designed to swap between APF and non-APF authorized states. You can do the APF to non-APF switch relatively easily. But it is generally a one way street. TSO does it by having two TCB trees. TSO starts up APF authorized, but resets the APF when the TMP does an ATTACH. But before that it creates an APF authorized subtree. When you run an APF authorized TSO program, it is run on the APF subtree and not the normal subtree. The normal subtree is frozen via the STATUS STOP operation during APF authorized function to decrease the likelihood of cracking the APF code. CICS switched back and forth using its SVC somehow (I don't know the internals). Now, being the weirdo that I am, I'd likely do my APF authorized work by using the UNIX fork() and exec(), where I exec() a module which is in the UNIX filesystem marked as APF authorized. Depending on what I need to do, I would either use shared memory (shmat) or set up a UNIX bidirectional unnamed PIPE if the APF task worked more like a server and would be invoked multiple times. It's just seems easier to me. Or use UNIX message queues for communications. I have a better understanding of using pipes. The plus of the UNIX solution is that the invoker does not need to be APF authorized at all. It just needs to be able to do the UNIX fork() and exec() of the APF authorized service program. I'd likely secure the service program by having the appropriate UNIX security on the executable file in the UNIX filesystem (using ACLs if necessary). An alternative / enhancement would be to have the UNIX program do a RACF security call of some sort to see if the invoker is authorized. This latter would be better if the routine is multifunction where the sub functions need to be individually authorized, perhaps with differing access lists.

Re: REXX INCLUDE ?
Many moons ago when I was a sysprog, I wrote a couple of REXX external functions in assembler called STEMPUSH and STEMPULL that allow you to pass REXX stems between execs in the same address space. It does this by placing the REXX variable name and value into a dataspace stack and then you pass the dataspace token as a parameter between the execs (STEMPUSH places items on the stack and STEMPULL retrieves them). As far as I know the code still works and you can find it on the CBT tape website (www.cbttape.org).

Re: *IEA061E REPLACEMENT ASID SHORTAGE HAS BEEN DETECTED
The most common reason for DB2 address spaces to be marked non-reusable these days is that they have a cross-memory bind to the RRS address space. You *could* probably relieve the shortage by stopping and re-starting the RRS address space - however there are implications to doing this while you have active workload that could be using RRS services. Do you shutdown your DB2 subsystems on a regular basis? If so - maybe you need to consider if you still need to do this. The more often you shutdown DB2, the more chance you have of chewing up the ASVT slots.

The documentation that I can find is not really very helpful. Or I just don't understand it. But I'm wondering what, if any, is the relationship between PSAAOLD and either the home address space or the primary address space. I know that a PC can do a space switch. In that case, the primary address space becomes the switched to address space. The switched from address space (I think) becomes the secondary address space. And the home address space stays the same. So, if I write some code which is invoked via a PC-ss instruction (not likely!), is PSAAOLD updated to point to the new primary address space? Or is it left as-is? I only ask because the address is not mentioned in the Principles of Operation, but a comment in the DSECT says fixed by architecture. Which indicates to me that the hardware uses or modifies it in some way which is not documented. What brought this on is a product which works on z/OS 1.10, but abends with an S0C4-11 on z/OS 1.12. The code appears to be using a pointer to the job's ASCB to look at some data in the job's SSIB. However, it appears that the primary address space is not the job's, but the Master Scheduler's. This is for an *OMVSEX substep which I __think__ is going through termination. Needless to say that using TCB pointers from one ASCB while a different ASCB is actually the primary is fairly well a guaranteed S0C4-11 since TCBs are not at the same virtual address in all address spaces (in primary addressing mode as this code is). Perhaps another question I should ask is: Is there a simple way to determine if a given ASCB address is the current Primary Address Space's ASCB?

Re: PSAAOLD question - when is it updated?
The following could explain what you are seeing but is based on a fair amount of guesswork : (1) ISV code using some sort of BPX* service that results in new ASID being created to perform the work - one of those *OMVSEX chaps (2) ISV (or IBM) code that runs in the new ASID wants, with good reason, to setup a ASID-level RESMGR routine to clean-up when the BPX-thing terminates. (3) RESMGR code uses some sort of pointer to a TCB in the now-terminated ASID (4) TCB addresses *can* be similar in different address spaces (obviously they are not the same thing) (5) RESMGR routine has (for years) been processing the TCB address passed to it and finding a valid address in ASID(0001) - hence there has been no abend (6) Something has changed in R12 that has made that TCB address not valid and the bug (that has been there for ages) now suddenly bites.

Re: SYS1 Datasets and it associated product names
There is a master list of registered product prefixes (three letters) that describe which IBM and ISV products are associated with them. In SMP/E terms, typically this means the three letters after the S or A in the LLQ of the product dataset. For example, SGIM in the LLQ (or DDDEF) will mean SMP/E as GIM is its product prefix I am unsure if this list is generally available, however most ISVs will either have a pre-registered range of prefixes that they manage internally or will request a new one for a new product.

For example SYS1.SIGY* datasets are related to Enterprise Cobol. There isn't any one document. You need the program directory for each product. But since most of the products come with a ServerPac, you can use the CPAC.PGMDIR softcopy version. You won't find the entire data set name, just the LLQ (low level qualifier), which matches the DDDEF name in SMP/E that is required. Another place you can find the information is the Serverpac Installing Your Order document.

Re: ASC. Mode
Home space mode exists for the very small minority of cases where instruction fetch uses the home address space rather than primary. I imagine that there a very few people outside of core z/OS developers that use this facility and other than knowing it exists, us mere mortals should just carry on happily in blissful ignorance.
