XRC Consistency Group Time Report.
Hi, We have an XRC session with 590 volume 3390 model 9, which is established on disaster recovery site on 450 k far from our local site. The connection is STM1 150 mbs between local and disaster recovery site. we are using Cisco MDS 9222i as a switch between ESS on local site and SDM on disaster recovery site with one channel. I have three question : 1- How can I find consistency group time and the delay time? 2- Why the Batch jobs on primary ESS take double execution time? 3- How can I control the delay time?

Re: Defined capacity
Al, To clarify my statement, if needed: when I set up the z196's with GCL, I did a lot of research on what tools were available and which were usable. There I read, that IRD Weight management is stopped when an LPAR is soft capped. I do not remember whether I interpreted this as being capped by both DC and GCL, or that I actually read this. I have never used it, so I don't have experience with the combination of the tools.

Re: Low priority workload
Anyway, I decided to define a resource group with just 100 SUs to force batch down. Surprisingly batch still used up to 2000 SUs, because WLM promoted the batch workload due to any blockings, enqueues or locks batch held. So promotion by WLM might be another reason at your site that batch runs better than expected. You can verify this with the Workload Activity report, it includes a column Service and Promoted. Hmm, did you verify that 2000 SU/sec were in fact used at a promoted dispatch priority? A z196 model 7xx (just as a typical example) delivers between 33,000 and 61,000 SU/sec per processor. Resource groups work by marking the work dispatchable/non-dispatchable for multiples of 1/64th of the time. Therefore, a single logical CP could deliver between roughly 500 and 950 SU/sec. Depending on the type of resource group, the number of logical processors within the scope of your resource group (i.e. system or Sysplex), and the amount of work running at a higher priority you may well end up at that order of magnitude for the achievable granularity for *that* resource group in your environment.

Re: XRC Consistency Group Time Report.
Manshadi, 1- How can I find consistency group time and the delay time? Look at the XQUERY command. I think it would be something like XQUERY VOLUME(ALL) STATUS but check the manual. This is issued against the STM and it is the consistency time of records applied to the secondary volumes, and not the latest time in the XRC journal. 2- Why the Batch jobs on primary ESS take double execution time? I'm guessing you have flow control turned on. A 150Mbs OC3 link is barely 15MB/sec, and eight channels of FICON 8S can write at 5600MB/sec. That makes your outflow rate around 0.3% of the inflow. This is the worst case and it would take a few seconds for XRC to reach maximum cache usage and drop the link. This is called a sidefile puncture. Flow control prevents this by slowing down writes as the XRC sidefile uses more cache, which in turn slows down your batch. You mentioned an ESS, which means you may still be on ESCON. Even so, 8xESCON can write at 136MB/sec, which puts your link capacity at 11% of the potential write capacity. In simple terms if I write 136MB in one second, and send 15MB in the same second I have accumulated 121MB of side file. In 9 seconds it is a GB, and in 15 minutes it is 100GB of cache used by the sidefile. How much cache do you have, and if you are using FICON this happens much faster. You also need to provide adequate MIPS in the remote site for the SDM to read and apply record sets from the Primary storage. This can also cause the sidefile to grow and accumulate in the primary storage and trigger flow control. 3- How can I control the delay time? You need to match the bandwidth between your primary site with your remote site. Understanding your write rate profile by time of day with XRC suspended will give you an idea of the peak demand. After that it is good old capacity planning and perhaps investment in something faster than OC3. If your ESS is actually a DS8K you may be able to get over the hump by adding cache, but it still comes back to understanding your unfettered write rate.

Re: I do not understand S0C6 on CDSG
For a location within dynamically obtained storage Paul Gilmartin's scheme of using execution-time modulo (congruence) arithmetic is inescapable.. Unless the GETMAIN or STORAGE OBTAIN specifies BNDRY=PAGE. In that case the quadword can be defined with DS LQ within your DSECT. Fortunately, it does not require Houdini to escape the inescapable in this case or to avoid getting storage on a boundary more than you need. GETMAIN (and its equivalent STORAGE OBTAIN,LINKAGE=SVC/LINKAGE=BRANCH) and STORAGE OBTAIN (LINKAGE=SYSTEM) have supported STARTBDY since approximately 2000. STARTBDY=4 will get you an area on a quadword boundary. CONTBDY is also supported mostly for cases where you are trying to avoid your area crossing a page boundary. As has been pointed out, assembler does have 0LQ along with SECTALGN. For modules, the system supports only doubleword and page boundary loading, which do not have necessary correlation to the placement of CSECTs within the modules.

If I code SECTALGN(16) for a Binder invocation I get alignment on a doubleword boundary, at an address A such that A = 0 mod(16). If instead I code STARTBDY=16 in a STORAGE GET macro I get alignment on a 2^16 = 65536-byte boundary, at an address A such that A = 0 mod(2^16), i.e., A = 0 mod(65536).

Its probably because oclass, although not a special SDSF/REXX variable as such, is in fact a column name in SDSF which you would use if performing other tasks with SDSF/REXX and somewhere along the line it didn't like me using that...

I should of course have written STORAGE OBTAIN and not STORAGE GET. I have also verified that Edward Jaffe's clarification is entirely correct. I am now more than a little curious to discover how this particular bug was discovered. It is clear that one can specify GOFF and quadword alignment and then, avoiding with care or having had the blind luck to avoid any GOFF features that are not supported by the linkage editor (or the binder pretending to be the linkage editor), obtain a load module. What is not entirely clear is why anyone would wish to do so. (I can think of a scenario or two, but none is very plausible.)

Gauss invented it as an early adolescent; and now, 250 years on, the rest of us should be able to use it, at least as adults. More generally---I will not labor this argument---there are many situations in which it seems to me that CNOP is the most natural device to use to obtain unusual or varying alignments within an instruction stream, not least because its effect is local and not global.

Re: I do not understand S0C6 on CDSG
I complained not so much about the inconsistency as about the confusions it gives rise to. For SECTALGN(I) the integer I must BE a power of 2. For STARTBDY(I) the integer I specifies the power of 2 the value of which is the alignment specified. Now the integer 0 is not a power of 2. (2^-2 = 1/4, 2^-1 = 1/2, 2^0 = 1, 2^1 = 2, 2^2 = 4, . . .) It thus cannot be an argument of of SECTALGN. Zero can, however, be an argument of STARTBDY. STARTBDY(0) = 2^0 = 1, i.e., byte alignment. Then STARTBDY(1) = 2^1 = 2 STARTBDY(2) = 2^2 = 4 STARTBDY(3) = 2^3 = 8 STARTBDY(1) = 2^4 = 16 STARTBDY(1) = 2^5 = 32 . . . STARTBDY(12) = 2^12 = 4096 . . .

Re: I do not understand S0C6 on CDSG
If the Wikipedia article, http://en.wikipedia.org/wiki/Modular_arithmetic#Residue_systems, is correct: In mathematics, modular arithmetic (sometimes called clock arithmetic) is a system of arithmetic for integers, where numbers wrap around upon reaching a certain value-the modulus. The Swiss mathematician Leonhard Euler pioneered the modern approach to congruence in about 1750, when he explicitly introduced the idea of congruence modulo a number N.[1] Modular arithmetic was further advanced by Carl Friedrich Gauss in his book Disquisitiones Arithmeticae, published in 1801. Then Euler invented it, and Gauss improved it.

Re: CA-TSO/MON replacement
AFAIK, there is no direct replacement. I presume you are (or have been) using this to track TSO command usage. Most installations used this as input to MICS and/or MXG.

AMASPZAP SECTALGN Bug (Was: I do not understand S0C6 on CDSG)

What is not entirely clear is why anyone would wish to do so. (I can think of a scenario or two, but none is very plausible.) This bug in AMASPZAP was discovered by one of our customers. He tried to ZAP one of his own exits and the ZAP failed. We use GOFF and SECTALGN(256) for all of our in-house product build assemblies. We also specify GOFF and SECTALGN(16) for any install-time, SMP/E-driven assemblies in the field for user exits, etc. that have the potential to include IBM code or macros that use 'LQ' constants.

Re: DFHSM QUESTION - DUPLEXING CHECKLIST
Each recycle process only takes only 50% more drives: three instead of two. Unless it has recently changed, one annoying thing about DFHSM in a tape-drive constrained environment is there is no easy way to put an absolute upper bound on the maximum number of drives needed concurrently by all DFHSM tasks. Yes, you can separately restrict the number of daily backup tasks, daily ML2 movement tasks, and migration recall tasks; but this doesn't really address the unpredictable concurrent demand from asynchronous ML2 recall requests and demand backup requests that may go directly to tape; and those requests can occur at inconvenient times, like when ML2 migration, or auto-backup to tape, or recycle is in progress. If you want to more-tightly restrict the total number of drives used by unscheduled DFHSM tasks during scheduled tasks with high drive demand, there is no easy way to do just that, and the greater drive requirements with duplexing can make this more of an issue. I would never use DFHSM with today's high-capacity cartridges without duplexing, but in some environments duplexing may require adding additional drives. JC Ewing On 02/26/2013 12:30 PM, Staller, Allan wrote: 1) be aware that duplexing for backup and migration are separate commands. 2) recycle, ml2 migration and volume backup will now take twice as many tape drives as before. You may have to change the limits on the number of backup tasks, migration tasks and recycle tasks you run concurrently to fit within physical constraint (# of tape drives available). 3) Plan on a program of recycling all existing media to get them duplexed.

Re: AMASPZAP SECTALGN Bug (Was: I do not understand S0C6 on CDSG)
My point about 'blind luck' was different, it was that many things doable once GOFF is in effect are supported only for inclusion in program objects. Many GOFF 'object modules' cannot, that is, be link edited into a load module. The situation is complicated; many program objects can, for example, be converted into load modules; many others cannot; and vice versa. Link editing GOFFs successfully, including them in load modules, thus requires either (and preferably) care or 'blind luck'. -- John Gilmore, Ashland, MA 01721 - USA t. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

What I was more thinking of was that on the 3350 an optimum block size was 6KiB, 3 times the 2KiB page size supported on the S/360 (370?) So it might have been useful to page in 6KiB quanta, and alignment on a 6KiB boundary (not a power of 2) might have been useful.

I have no desire to reignite old conflicts in this area, but I can attest that the ONLY alignment values actually supported by contents supervision were doubleword and page, regardless of what the binder doc claimed. Most of the GOFF functionality introduced in PM3 circa mid '90s existed only in the designer's minds. As perhaps the only person on the planet actually trying to exploit that functionality in vendor code I had an almost daily dialog with developers in the assembler, binder, contents, DFSMS, media manager, PDSE and other component I've probably long forgotten. Even things you wouldn't think of (e.g. AMBLIST) got hit. So i am not at all surprised that bugs are still being uncovered now. However, the alignment of storage occupied by the load module/program object is immaterial to the alignment of storage operands. PAGE alignment was always available and would give the desired results using the techniques already discussed. For those worried about a few bytes wasted in a page, the virtual storage macros were long ago adjusted to allow specification of boundary alignment via CONTBDY and STARTBDY.
