Re: DB2 image backup and DFSMSdss dataset backup
We put DB2 databases in their own storage group, and don't take DSS backups. Same with IMS. Application needs to be shut down and use DB2 / IMS / Database backup methods.

REXX and CEEPIPI questions.
I am trying to look at how to use the PCRE from Ze'ev Atlas in a REXX program in a REXXish way. PCRE is written in C and is basically implemented as a bunch of subroutines. Being in C means this requires LE. I could just write my code to be LE compliant and then invoke it from REXX via a LINKPGM, or similar, method. I could pass the results back by having my routine use IRXEXCOM to create specific REXX variables which could then be used in the rest of the script. Yes, there are better ways, but I'm just thinking out loud right now. I was also looking at using CEEPIPI somehow to establish an LE environment which would last across calls to my PCRE functions. I have been reading the books. But I can't find the answer to my first question. Which is: If I call an HLASM routine which: (1) is not LE compliant; (2) uses CEEPIPI function init_sub to set up LE environment for calling subroutines; (3) returns to REXX. Will the LE environment stay around? If it does, could it cause problems with REXX or even TSO itself? Could it cause problems if the user were to invoke an LE enabled main routine (written in C, COBOL, ...) via a TSO CALL or ADDRESS LINK type invocation? If the user does invoke an LE program, will that affect the CEEPIPI set up environment (as in terminate it)? Instead of init_sub, should I use init_sub_dp? It seems to have some advantages, but is more restrictive. Mainly it seems to be a way to avoid the possible problems of leaving an LE environment active. Also, I am not totally sold on having an LE environment hang around. I do know that it saves on start up and shut down time. But I don't know if it is worth the effort because I don't really have a handle on how many PCRE invocations are going to be done in a single execution of a REXX program. -- This is a test of the Emergency Broadcast System.

Re: Missing HSM backups
Hello, just a thought but are the datasets being backed up via an hbackds command? they might have an explicit retaindays coded (new in Z/os 1.11 i think) which would negate the mgmtclas settings. Also, have another look through the hsm backup logs when expirebv is running for the datasets in question. The datasetname would have the dfhsm.back.t** prefix so all you could recognise would be the 1st 2nd qualifiers rather than the full datasetname but there should still be an entry, which would give you the deletion criteria. If your system runs daily dcollects with the hsm migd bacd parms you could strip out (sas or rexx) pertinent data (See AMS for Catalogs, Appendix F, record type B) about your missing datasets to help narrow things down.

It seems to have some advantages, but is more restrictive. Mainly it seems to be a way to avoid the possible problems of leaving an LE environment active. CEEPIPI init sub creates an LE environment and returns a token to the same. The token is passed to the ceepipi call sub function along with other parms. The LE environment represented by the token is usable on that tcb until destroyed by using ceepipi term function. init sub dp allows you to create multiple LE independent environments under the same tcb. verify your need before using this. best performance in calling the subroutine is to use is to use call sub addr. This called the subroutine by address instead of name. if you are going rexx-pipi-subroutine in high volume, call sub addr is worthwhile. If you are going rexx-pipi-subroutine just once or twice then call sub is fine. init sub dp has other characteristics that are useful in a multi-tcb environment.

Re: REXX and CEEPIPI questions.
I think you were referring to the CEEPIPI functions named call_sub and call_sub_addr. call_sub is the CEEPIPI subfunction which calls a LE enabled routine by symbolic name (like LINK does). Where call_sub_addr is the CEEPIPI subfunction which calls an LE enabled routine by its load point address (like SYNC does). In either case, REXX itself will somehow (LINKPGM or otherwise) give control over to my routine which will set up things, then invoke the PCRE appropriate subroutine(s) as needed, and finally somehow pass back the results (likely via REXX variables the way ISPF does) back to the REXX program.

There is no memory pentaly for immediate operands, while memory references can be quite costly: an item taken from memory can displace other items in the data cache, or they might cross a cache-line or memory-page boundary, or require paging.

Re: Benchmark of Relative instructions vers Base+displacement ones
John Ehrman knows much more about what kinds of older mainframes are still in use than I do, and I imagine that he had good reason to use the qualifying language . . . so if your processor supports useful immediate operands, take advantage. Still, the extended-immediate facility dates back ten years now, to June 2003; and I have found the 'new' instructions it makes available very helpful. The FLOGR instruction alone has, for example, revolutionized the way in which I do bit-map processing. I would urge any HLASM programmer who is not already using these instruction to familiarize himself with them, for reasons of convenience and code compactness as well as the performance reasons John mentions. Let me also take this opportunity to add my personal view that base-register-displacement schemes are at best obsolescent in new code. There is no excuse for using them ab initio. Equally, of course, there is no compelling case for their doctrinaire elimination from old code.

Subject: PS-E not releasing with HSM Migrate/Recall
Hi everyone,
I may be all wet, but this is my best resource for help on this issue until
I get back on support with z/OS 1.13.
I am running z/OS 1.11 (unsupported). Back in January, I applied all
maintenance to bring it up to RSU1301.
For years, I have had a MGMTCLAS of ATMBKUPS with conditional partial release
and a DATACLAS of TMBKUPLG:
[snip]
I know that the multi-volume striping will not do the partial release at close,
but I thought that HSM migration/recall was resulting in the release of unused
space in these datasets.
Last week, I had several failures to allocate these datasets and noticed that
even after recall, these datasets remain at 65616 tracks usually about 5% used.
Have I been fooling myself that this large (never run out while actually
writing the SMF data) and release at migration ever worked? I suspect IBM will
not be real helpful until I can reproduce on z/OS 1.13 which will be later this
year.

Subject: RE: PS-E not releasing with HSM Migrate/Recall
Ah, well. It was a flash in the pan suggestion since we don't HSM here. The
only other twinge I can think of is whether secondaries exist since it's
Conditional vs. Yes. Are there more than one extent on each of the volumes?
hmmm... just looked at what you cut/pasted and I think that answer is there
are no secondaries. Allocated extents: 2 c/w VolSer: + indicates to me there
are probably two volumes with each having one primary extent. That would
mean they don't qualify for Conditional Space Management. I'll bet you get
equivalent results with Conditional Immediate. You might try YES to see if
you have better luck.
If I remember correctly, Extended causes a primary extent to be allocated on
each of 'Unit count' volumes and, as you fill the file, secondaries *might* be
allocated followed by additional volumes if you have DynVolCount set. We
also don't do Extended yet; we're not a big enough shop for it to benefit.
x37 abends are almost a non-existent with stripped/extended as a default vis
DATACLAS
Yes, it is stripped on 2 volumes, and it did not require allocation of any
secondary extents.
a nonzero secondary space allocation has been specified for the data set
But, it is still desirable (since secondary is defined) to reduce the actual
disk usage to the current utilization on recall. I haven't looked, but I am
pretty certain that all those empty blocks aren't taking up space on my virtual
tape.
a nonzero secondary space allocation has been specified for the data set
Aside: is migrate/recall how Space Management is achieved by HSM? Just
curious.

Probably about the virtual location. We are getting a S213-04 when trying to flash this one volume. The VTOC on that volume is at a different location than the target flash output volume. She is trying to say that will cause a problem. It's an older volume and we have since changed the standard for where and how big we create the VTOC and VTOCIX. It contains the RMM CDS and as such is not easily moved. If it was just regular datasets, we would just DFDSS move them to another volume and then re-init it to look like our other volumes.

Peter Farley opines: They [IBM] have, time and again, shown themselves quite capable of deliberately reducing the effectiveness of new technology to preserve their revenue stream for a few more quarters. Examples? I'll offer a counterexample: the System/360. IBM led the electromechanical tabulating and accounting equipment market, and the System/360 utterly destroyed the very market IBM dominated. The System/360 was either going to be history's stupidest act of corporate suicide or one of history's most brilliant business successes, depending on how it turned out. More recent examples are obviously more relevant than older ones. No points awarded if the examples have other plausible motives available. By the way, this question has just been answered for COBOL. Enterprise COBOL Version 5.1 is available, now. Turn on the new compiler optimizations and measure the results. They be good. In my opinion it's delusional to think IBM would invest huge sums and many years developing (and shipping!) an entirely new backend for a product it didn't believe in and that it didn't expect to sell.

Re: REXX and CEEPIPI questions.
I find it much easier to use subcommand enviromments http://users.tpg.com.au/crayford/rexxre.txt. I setup the CEEPIPI environment in RTKSUBCM, allocate all the memory I need for the command processor routines (saveareas etc) and store a control block in the SUBCOMTB_TOKEN field. When the command handler gets called I grab the control block from R1 (no need to GETMAIN storage areas) and forward the call to the LE routines via PIPI. Those cost of parsing the command string is significantly less than the overhead of GETMAIN and name/token services calls. On 11/07/2013 1:38 AM, John McKown wrote: I think you were referring to the CEEPIPI functions named call_sub and call_sub_addr. call_sub is the CEEPIPI subfunction which calls a LE enabled routine by symbolic name (like LINK does). Where call_sub_addr is the CEEPIPI subfunction which calls an LE enabled routine by its load point address (like SYNC does). In either case, REXX itself will somehow (LINKPGM or otherwise) give control over to my routine which will set up things, then invoke the PCRE appropriate subroutine(s) as needed, and finally somehow pass back the results (likely via REXX variables the way ISPF does) back to the REXX program.

AFAIK there is no capability in z/OS Rexx to call a subroutine by address. I'm clearly showing off my deep and extensive REXX knowledge. ;-) John, I strongly suspect that the efficiency of a CEEPIPI setup will more than pay you back for the complexity of the setup for all but a very few calls to the PCRE subroutines, i.e. in all but the very simplest of use cases. I would set up the CEEPIPI environment and store the returned token in a suitably obscure named Rexx variable (like ___C_E_E_P_I_P_I___) and retrieve that variable on each call to the PCRE functions. Use the token value if it is there and set up CEEPIPI if it is not yet there. Or you could require a Rexx variable to be passed as the first argument to all functions in which you store the CEEPIPI token value, putting the burden on the programmer to keep it intact and pass you the right value every time.

PCRE is written in C and is basically implemented as a bunch of subroutines. Being in C means this requires LE. I could just write my code to be LE compliant and then invoke it from REXX via a LINKPGM, or similar, method. I could pass the results back by having my routine use IRXEXCOM to create specific REXX variables which could then be used in the rest of the script. Yes, there are better ways, but I'm just thinking out loud right now. I was also looking at using CEEPIPI somehow to establish an LE environment which would last across calls to my PCRE functions. I have been reading the books. But I can't find the answer to my first question. Which is: If I call an HLASM routine which: (1) is not LE compliant; (2) uses CEEPIPI function init_sub to set up LE environment for calling subroutines; (3) returns to REXX. Will the LE environment stay around? If it does, could it cause problems with REXX or even TSO itself? Could it cause problems if the user were to invoke an LE enabled main routine (written in C, COBOL, ...) via a TSO CALL or ADDRESS LINK type invocation? If the user does invoke an LE program, will that affect the CEEPIPI set up environment (as in terminate it)? Instead of init_sub, should I use init_sub_dp? It seems to have some advantages, but is more restrictive. Mainly it seems to be a way to avoid the possible problems of leaving an LE environment active. CEEPIPI init sub creates an LE environment and returns a token to the same. The token is passed to the ceepipi call sub function along with other parms. The LE environment represented by the token is usable on that tcb until destroyed by using ceepipi term function. init sub dp allows you to create multiple LE independent environments under the same tcb. verify your need before using this. best performance in calling the subroutine is to use is to use call sub addr. This called the subroutine by address instead of name. if you are going rexx-pipi-subroutine in high volume, call sub addr is worthwhile. If you are going rexx-pipi-subroutine just once or twice then call sub is fine. init sub dp has other characteristics that are useful in a multi-tcb environment. Also, I am not

Re: Benchmark of Relative instructions vers Base+displacement ones
On 7/10/2013 11:54 AM, John Eells wrote: And, finally, that the branch instruction itself does not stand alone. One must load a register to use it as a base in order to establish addressability, and load another to use it as a displacement register, and Load instructions can cause real memory (vs. cache) accesses. So, it seems to me there can be some applicability to relative branch as well. Branch prediction is a wonderful thing for optimizing loops and other repetitive branch paths, but it makes it difficult to get meaningful branch benchmarks. Relative branch, in addition to providing relief from the oppressive 4K base register domain, should help a program perform better because: 1. Branch prediction occurs early in the pipeline when there is no access to register contents. With relative branch there is no need for the processor to waste time double-checking the branch target address once the contents of the base register are actually known. 2. AGI (address generation interlock) can cause an instruction using a base register to run *brutally* slowly (i.e., stop for a while) if it executes shortly after the base register is loaded. This applies to based branches as well as other types of instructions. Base registers get loaded more often than people think e.g., LM when returning from a subroutine. With relative branch there is ZERO possibility of AGI. 3. Freeing up code base registers for other uses allows program code to be better interleaved by compilers, HLASM programmers that know what they're doing, and OOO execution pipelines on the latest machines. -- Edward E Jaffe Phoenix Software International, Inc 831 Parkview Drive North El Segundo, CA 90245 http://www.phoenixsoftware.com/ -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
