Re: Can DFSORT do pattern matching?

Sent by: IBM Mainframe Discussion List IBM-MAIN@bama.ua.edu I'm writing a series of articles for my Tuning Letter about service level agreements and mentioned in the last issue that I strongly believe in single period batch and two-period TSO service classes. One of my readers asked me to clarify, so I pulled up an old article on multi-period batch. It will soon be added to our website as part of the z/OS 101 Primer articles that are free to the public - http://www.watsonwalker.com/articles.html. I've included the entire article below, but would like to qualify that I consider work like DDF to be more like TSO, needing two periods, than batch. (I've kept this as plain text, so it isn't pretty. Sorry.) Best regards, Cheryl == Cheryl Watson Watson Walker, Inc. www.watsonwalker.com == Multi-Period Batch What are the advantages and disadvantages of running batch in single-period service class versus a multi-period service class? We must have heard this question at least six times at the latest SHARE. Although we did provide an answer in our September 1994 TUNING Letter, we think it's time for an update. We'll address the considerations for both batch and production jobs, because they tend to have different requirements. Test Batch If your intention is to provide the best turnaround to the most people by allowing large resource consumers to suffer slightly, then you'll want to use the typical method of managing test batch jobs. That method simply consists of getting as many of the small jobs through the system, at a high dispatch priority, as you can. You would then let the larger jobs run at a lower priority, and possibly miss their service goals. This technique is used in almost every data center today. The only difference is in how it's implemented. Let us describe the two typical methods and the pros and cons of each. Priority by Job Classes The most common technique is to define a set of test batch job classes that allow a certain set of resources. For example, you might define the following test batch job classes: A - Less than 5 seconds CPU time, no tapes - 10 minute turnaround B - Less than 15 seconds CPU time, 0 to 1 tape - 30 minute turnaround C - Unlimited CPU time, 0 or 1 tape - 2 hour turnaround D - Unlimited CPU time, unlimited tapes - overnight Then you would define some JES initiators to process these jobs. There are dozens of ways to set up initiators, but a typical scenario, might be: Init 1 - Classes: A Init 2 - Classes: A Init 3 - Classes: B Init 4 - Classes: BA Init 5 - Classes: CA Init 6 - Classes: DCBA You would then set up a single period service class for each job class. As one example: TSTBATA - 90% within 10 minutes TSTBATB - 90% within 30 minutes TSTBATC - period 1 = velocity of 20%; period 2 = discretionary TSTBATD - discretionary We're making an assumption that there aren't enough ended class C jobs to allow a response time goal. The advantage of this technique is that the initiators will determine the highest priority jobs to allow into MVS. If the operators feel that the system is too busy at the moment, they can close down the initiators in order of 6, 5, 4, 3, 2 and 1. When jobs in classes A and B get onto an initiator, they'll go into a single-period service class and stay at the same dispatch priority while they're executing. For those job classes, the first jobs on an initiator are normally the first jobs completed. Job classes C and D, on the other hand, have unlimited CPU time. They might need 20 seconds of CPU time or three hours of CPU time - you don't really know. Therefore, the multi-period batch allows you to push the smaller of these large jobs through the system by setting the dispatch priority of period one to provide higher performance. Priority by Period Prioritizing test batch jobs by their actual use rather than their anticipated use is another common technique. In this method, there would be just one test batch job class. The initiators would be used to manage the number of test jobs in the system, but wouldn't differentiate between the short jobs or the long jobs. A service class for this method might have four periods and look like: Period 1 - 90% within 10 minutes

Frank,
It is terrific that you are getting an improvement with BLSR.
I suspect you are using a vanilla copy of an example in the BLSR manual
similar to Peter Farley's example in his post. The problem is these parms
do
not get the best performance from BLSR.
The missing value is DEFERW. This is explained at
http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IEA5J600/3.1.1?SH
ELF=iea2bkb3
http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IEA5J600/3.1.1?S
HELF=iea2bkb3DT=19940301112926CASE DT=19940301112926CASE= about three
quarters of the way down the page. Using Peter's example I would suggest
you
should use:
//MYKSDS DD SUBSYS=(BLSR,'DDNAME=MYKSDS#','RMODE31=ALL',
// 'MSG=I','BUFND=256','BUFNI=10' DEFERW)
//MYKSDS# DD DSN=HLQ.MY.KSDS,DISP=SHR
If you do omit DEFERW a CI will be written to the KSDS every time you
update
it. It will stay buffered for a read buffer hit, but if you update 100
records in the CI you will write that CI 100 times. Not a huge problem for
most modern DASD, but if you are running synchronous remote copy it will
be
painful. With DEFERW an updated CI will written when the LSR algorithm
decides it is no longer active enough to remain in the LSR pool. You'll
also
see an unusual effect where all changed CI are written to KSDS at end of
job.
DEFERW also helps the performance of sequential inserts that do not use
SIS,
and CI and CA splits. It's an often omitted must-have for BLSR.
NB it's a good practice to set BUFNI to the number of records in the Index
component of the KSDS, plus 10%. Again based on the example, if you have a
three level index with 11 index set records your sequence set will pollute
the buffer hits on the low level index set records (the high level index
set
record is probably the most touched CI in the KSDS).

23.2 minutes versus 1.1 minutes. 1,123,000 EXCP versus 10,704 EXCP.
BTW, to Steve Comstock, there is no AIX on this file. Just a 17 byte
key
where the first byte is the record type ('0' - '5') and the remaining
16
is the
'actual' key in the format appropriate for that particular record type.
The idea of putting the record type at the end rather than the beginning
is an
interesting idea. Unless there's some way of doing that without having
to
change any programs I don't think we'd want to take the time. However I
am
interested enough to try it with this one program and see what effect it
has.
Thanks!

Sent by: IBM Mainframe Discussion List IBM-MAIN@bama.ua.edu I've been asked to look into seat based licensing for z/OS and for this I need a unique z/OS image name for the license. I can see that an LPAR has an ID (a number) and a name. The LPAR ID appears to be unique, but is the name unique or effectively unique? By 'effectively' I mean would a duplicate name be problematic. Also, are LPAR names and IDs normally paired/tied, or might they change? Would a license based on the LPAR ID rather than name be acceptable?

Re: Dedicated vs. Shared CPs

I think what you said about z10 corroborates my memory that Dynamic ICF Expansion was only supported on z9 and prior.

No. Not on a z9 and not the way you mean. The RMF report deals with what an lpar can look like when it uses Hiperdispatch. That is not available on a z9. Hiperdispatch semi-dedicates logical processors to physical processors depending on the workload. And most probably depending on the number of physical cps. (Which is why we asked for the number of your physical cps in the other thread - you haven't answered that!) Once hiperdispatch is on, a physical cp gets a weight, which can be low, medium or high. High amounts to being (semi-)dedicated. Does anyone run mixed like this, a dedicated number to cover the minimum expected MSU of an LPAR, then some logicals to float between LPARS? Everyone who uses hiperdipatch. Does anyone know what is needed in terms of outages/lpar resets to move from a completely logical CP environment to a mixed environment? An upgrade to a machine supporting hiperdispatch. Which means at least one IPL. But as you can see from my questions starting this thread, it is possible that you cannot use hiperdispatch - whenever your logical to physical cp ratio is so bad that 4 or more logical cps compete for one physical, due to the number of lpars you have, for instance. In the very first presentation I heard (by Bob Rogers) about hiperdispatch, he said that it will turn itself off if the ratio is really bad. I haven't heard that confirmed anywhere, though. And coming from a z9 presumably to a z196, chances are very good that you would loose physical cps to keep money down. Try making your bosses understand that they cannot use the same number of logicals when the number of physicals decreases Barbara Nitz -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.

Re: Turning on additional CPs
This used to be a big deal back in the 3090 (and prior) days. Less so now as the numbers sustain us to very high numbers of engines without much discomfort. In the original case (3 going to 4) I wanted (a few days ago) to point out the engine speed decrease was slight enough to probably not be the cause. I might be wrong :-) but that's still my opinion... I know we've not really talked about MP ratios as a community for a very long time. I'm wondering what's been done in the past 15 years (other than multi-book machines since z990 and Hiperdispatch) to potentially change the picture. Anyone care to chip in? I'm also going to think about the effects of multibook and HD myself. On multibook I think it analogous to the old 280 and 380 models that were faster than the 200 and 300 models despite having the same number of engines (2 and 3 respectively) because of the second lot of cache.

Yes, I do. If so, this check runs at a 30 minute interval and checks the slot usage for each in-use local paging data set regardless of whether it was defined 'statically' or added via PAGE ADD. So... it does eventually recognize a changed configuration. Some of the ASM checks are set to re-run when a PAGE ADD/DELETE is issued, but ASM_LOCAL_SLOT_USAGE is currently not one of them. Open to suggestions As far as I am concerned, there is 'intelligence' missing in that check (my usual complaint with health checks). In our installation, we only have one device geometry, behind the same controller, and all page data sets are same size. So I expect the health check to recognize that adding a page ds to the overall config will relieve the 'performance impact' of 30% overall usage. Unfortunately, ASM does NOT prefer the new page ds, it is one of many, and as I indicated before, has never filled to the same slot usage as the others. Only IPL has ever evened out slot usage (and I am not talking about 1% difference, more like 20% difference on the same geometry and size! I think Skip mentioned this, too.) So the old, already-at-30%-usage locals and the new one are treated equal, so slot usage on the old ones increases over the 30% mark, and the check would still trip every 30 minutes because of that (if I hadn't set it to only check once per day until the next IPL). After it had alerted us to the condition once, it becomes basically useless for the life of the IPL. In my opinion, this health check should have the intelligence to recognize something about the configuration (same controller, same size data set) and change the checking parms accordingly, especially when a page data set was added. The check should obviously (as Kees indicated) behave differently if different percentage slot usage is due to different geometry and/or different size page ds. Now that I have established a daily graphic that shows slot utilization (as shown by Barry via MXG), I might get rid if that check completely and check my graphic instead. :-) Barbara -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.

Re: Very Lage Page Datasets (was ASM and HiperPAV)
I'm sure I don't count as like Kathy* :-) but... Contiguous Slot Allocation Algorithm is still in place so I also tout the 30% but... 1) I say this is not a falling off a cliff thing but hazard it to be more gradual than that - so a dynamic. 2) I also suggest people aim for free paging space generally 1.5x the LPAR's memory. Item 2 is a ROT I made up myself. :-) It's motivated by the need to have something to dump into - and it leans in the same direction as the Cont Slot Alloc Algorithm. I'm not sure the 1.5x number is right... ... I consider both the 30% and my 1.5x as STARTING POINTS. And I emphasise good paging subsystem design and adequate memory provision - even now.

Certainly with 4K pages (for the most part) and 3390-27 (or bigger) that 30% ROT doesn't apply anymore?50% of a mod-27 is still a helava lot of free slots. I think it still applies. My understanding has always been that the 30% usage (after which paging effectiveness drastically drops) applies to the algorithm used on the in-storage control blocks to pick the next free slot in a page data set. Unless that algorithm was redesigned, 30% of 44.9GB per page dataset is what you should not exceed (just as the health check says) in AUX usage. Redesign of that is IMHO unlikely, just as using more than 2 IOs on a page data set simultaneously would require (an unlikely) redesign. That sounds right as far as the algorithm, but I thought the paging effectiveness was related to likelihood of not being able to find contiguous slots for group page outs after the 30% usage (based on old technology). So if I have 5 3390-27 locals and they are all equally used at 50%, the algorithms (CPU usage, not I/O) are going to pick one of them, then do the page outs. That paging will find contiguous slots and should be efficient. BTW, this is just an example, we still try to keep our 3390-27 local usage at 30% just like we always did with smaller local page datasets in the past.

We do so to fill 3390-9s and -27s with pagedatasets. I beg to disagree. :-) HiperPAV works on a per-IO-basis in the hardware, so ASM cannot 'reserve' an exposure (anymore). HiperPAV is for faster I/O turnaround and for reduction of IOS queuing times by giving another SSCH another 'exposure'. No SSCH, no HiperPAV usage. If no I/O is started because ASM knows there is one outstanding (as was the case in the past) then HiperPAV is effectively not used. Other than for the second case that Jim Mulder had detailed in the past. Hence my question if that is still true or if ASM now starts as many IOs as needed to get paging requests filled. For a page data set on a HiperPAV device, ASM creates two sets of channel program control blocks. If a single page read request come along while the first set is in use, ASM will use the second set to start another channel program to do the single page read. The purpose is to avoid having a single page read need to wait for a long string of pageouts to complete before it can be started. Jim Mulder z/OS System Test IBM Corp.

SMF73GEN Channel Generation Field - Modern Values
I'm seeing RMF SMF data from a z196 . One field in Type 73 intrigues me: SMF73GEN. I've seen values up to 5 before - 5 being FICON Express4 at 4Gbps. Anyone know what values 6 and 7 mean? These are the new ones in this set of data. And should I expect in general to encounter a value of e.g. 8? Wondering about FICON Express8 and Express8S and autonegotiation down. (SMF73GEN has different values for eg Express4 @4, 2 and 1 Gbps.)

Re: Calling all experts on SMFPRMxx SUBSYS
Charles Mills wrote: DB2 uses the subtype format as it uses the subsystem ID field but AFAIK does not use the subtype field (documents it as reserved). Seems to be fairly consistently written as . DB2 doesn't have subtypes because it has its own thing - called an IFCID. The IFCID is in the QWHS section of the record, not the SMF header. So it's not in a fixed position in the SMF record. I have DFSORT E15 exit code that allows me to select on IFCID (and other things not in fixed positions). The technique I use is to copy these sorts of fields to before the record and shift the record along. Then in DFSORT I use OUTFIL OUTREC to shift the record back.

Re: SMF73GEN Channel Generation Field - Modern Values
I think - and I've only loose proof - that 6 is FICON Express8 at 2, 7 is FE8 at 4 and 8 is FE8 at 8Gbps.

Was: Calling all experts on SMFPRMxx SUBSYS - How does Subsys of SILO work?
Topical: Just yesterday a colleague and I were discussing a user-defined (not SSI) subsystem - SILO - that a customer appears to have. You can guess (as I did) the origin of the subsystem. 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? In general I just wonder what this thing is and how it behaves and how prevalent it is. Oh, and why it's a user-defined subsystem in the first place.

Re: IBM manual formats
Funnily enough I mused on Kindle MOBI / AZW format re Redbooks on Twitter just now. (You can guess what I got for Xmas.) :-) I'd like to have the discussion on how to format for Kindle with the right people. In ITSO (the Redbooks people) we use Framemaker (at a fairly ancient level) so I'm not sure whether that could be taught to emit MOBI / AZW / Epub etc. I would think Information Development (Product Manual Writers) are using something else (once was Bookmaster, which I still use myself) and I don't know what the options are. It seems to me emission of HTML is a good intermediate step. I have to say even the O'Reilly books for Kindle are of quite variable quality, formattingwise. I'd be happy to have the discussion with appropriate IBMers and customers (the latter giving us some idea of demand for mobile reading formats). Anyone?

Personally, I prefer using the Web and BookManager format over PDF. But I cannot easily download those and view them offline. On the other hand, the PDF manuals are a royal PITA to me, except on my Kindle DX. Which is why I have a Kindle DX. They are a PITA because PDFs are formatted as a portrait mode, letter (or maybe A4) sized page. And since many of the manuals are two column, that means paging up and down while switching sides to read. The problem with the BookManager format, in addition to the not offline, is that I sometimes cannot read the diagrams. They aren't formatted correctly. Now, one of my favorite magazines has gone digital only. I have an Android app on my Xoom tablet which displays their magazine like a regular magazine - letter sized portrait. HOWEVER, they also have .mobi and .epub formats for reading on cell phones and other devices. I am wondering how difficult it would be for IBM to publish their manuals in .mobi or .epub format. This would make them much more readable on cell phones or other media such a the newer Kindles or Nook ebook reader. It would even help on netbooks, laptops, and desktop as it wouldn't force the letter sized pages onto a device which cannot render them nicely.

The only data required for the audit was the site's SMF data (and a smart program to read the SMF file!), plus a program that allocated and grazed the disk farm to capture all DSNAMES and attributes (which DCOLLECT would do now). From an intelligent examination of the names of datasets, which clearly indicated/suggested they were the software company's property, along with a listing of the names of the members of those load libraries, and a comparison to the SMF program names that had been executed, which demonstrated those programs were being executed from those libraries, the two companies withdrew their suit and countersuit, and reached agreements on licensing. And, after only the very FIRST report was reviewed by both parties! Quite a bit of additional analysis software had been prepared to tighten up the SMF-to-LoadLib connection, which would have analyzed the DDNAMEs used by these programs, but those programs were never used.

It's just XML with some extra taqs, so it shouldn't be too hard to do. Of course, that would mean that IBM would have to release the source for LP3820...*sigh*. Another thought: LP3820 already produces HTML output (albeit incredibly ugly HTML -- think 1980's HTML). The Docbook html2epub tools will eat HTML (obviously), so at least you'd have the text. Big hassle: the illustrations in the older manuals are in APF format, which isn't documented anywhere. You could probably transcode the PDFs with some of the Docbook .mobi support tools if you run them through pdf2ps, then through ps2mobi. Would totally break images and hyperlinks, though, and see above.

Re: Batch Capacity Planning - BWATOOL?
Mike, as it's been a week and no reply to your post I thought I'd bite the bullet and summarise my thoughts on Batch Capacity Planning in a blog post (or maybe two). (I'd been hoping some debate would ensue but none has shown up.) :-( But on your question of BWATOOL, its role was really to show what happens to a batch job when the engine speed of the processor it's running on changes. I'm not sure how that really helps when it comes to Capacity Planning. And I've not seen ACTIVE references to BWATOOL in a long time. If you really DO want to figure out the effect of an engine speed change you probably could roll your own - in MXG or whatever. You'd have to supply your own engine speed comparison, of course. And you'd have to understand that CPU queuing make the whole exercise a little fraught. Perhaps I'll touch on more-versus-faster as it applies to Batch in the first post. Cheers.

Re: SLR columns size D_MIGR_SP mbyte gbyte
It's just as well SOMEONE in IBM is still using SLR, unsupported though it has been for MANY years. :-) You could define a view over the table which just edits the display specification for the column that's overflowing. (Or, as you say, creates a column that is divided by 1024.) So I'd look up VIEW in the commands manual. Note this is NOT an RTFM answer. :-) As always when I see overflow I wonder what is causing the data to have values that big. Hope that helps.

In that case, MVCs could be considerably slower. I had been about to suggest the MVPG instruction, but it's quite possible that MVCL will use the same infrastructure if circumstances are right. One imagines that with fewer options and special cases to evaluate, fewer registers to tie up and none to update, for MVPG the setup would be shorter, and the execution at least as fast. But one's imagination is often not a good guide; I have a rather casual benchmark for these two (that is, MVCL of 4k on a page boundary vs MVPG with no fancy options) that shows MVPG just barely beating MVCL on a z10, and losing heavily on all earlier machines I had access to (P390, zPDT, MP3000, FLEX/ES and z9). John Gilmore's points are well taken. If I may suggest one more, loosely put, it is to use instructions for what they are usually used for (which is, even more approximately, what they are documented to be used for). This is likely to take advantage of hardware optimizations over time without forcing a tight binding to the hardware of the day. The assembler programmer does not have an easy way to recompile and take advantage of whatever the hardware implementors and compiler designers have come up with since the code was written.

AMATERSE and BatchPipes/MVS and SMF
Short version of the question: Does anyone know which access method AMATERSE uses to write untersed data out? Longer version: Does anyone have any practical experience of using it with BatchPipes/MVS aka Pipes? Particularly with SMF. Here's why I ask: The first thing I do when I get a customer's SMF data is to UNTERSE it and the second is to split it, based on eg record type. I'd like to combine the two - without asking Development to provide exits to AMATERSE. (I've not asked - they may be amenable.) Now, I know SMF is VBS not VB and therefore not supported with Pipes. However, in many cases I can get away with characterising it as VB and then Pipes could work. (I'd have to work on making AMATERSE believe it's writing VB, of course.) Thoughts? Any other way to save the disk space involved? I might actually try this. I'm spurred on by the enormous amount of data I get in support of CICS, DB2 and Batch studies these days.

The IPA is a possibility but looks to be populated via LOADxx and we've had issues with the HWNAME filtering causing problems with the CPC name. I've looked at IBM's CSRSI service and they have a neat setup where you can request information at the CPC, LPAR, or VM level *OR* any combination of the three. However, in IBM's infinite wisdom it appears they left the CPC name off the list of information returned via a CPC call sigh. They have a CPCNAME defined in the macro expansion but it is an ORG of the LPARNAME and is in the LPAR area, not the CPC area so it's not a matter of doing a single vs multiple call type.

Re: Hardware-assisted compression: not CPU-efficient?
Ron, is it generally the case that CPU is saved on read? I'm seeing QSAM with HDC jobsteps showing very high CPU. But then they seem to both write and read. Enough CPU to potentially suffer from queuing. (And, yes, I know you were talking about a different category of HDC usage.)

Re: 64 bit mode disabled
Tom Harper wrote: I'm not so sure. Many CICS shops have pointed out to me that they are forced to run hundreds of CICS regions for the simple fact that 2G is not enough address space to contain all of their programs. This requires them to spend an inordinate amount of time managing regions for the sole reason of address space exhaustion. Tom, I'm not really disputing what you're saying but I'd be surprised if many of those were limited by the program code - I'd be expecting concurrency of transactions to be an issue but not the set of load modules. Do you have examples where the CICS statistics (or other instrumentation) confirms it's the loaded modules that are the problem?

CICS Topology ... was Re: 64 bit mode disabled
One customer of mine has tens of thousands of test CICS regions. You want one? You get one - probably staying up the rest of the day after 15 mins playing with it. :-) For them it's not going to be single-CP constraints or virtual memory or anything like that. :-) Though the memory impact of all those regions is very severe. :-( (Just tossing in another data point.) But I still think for most customers the aggregate size of loaded (or ideally would be loaded) modules in a single region is not much of a factor. 100-200MB tops. I could be wrong. :-) Martin Packer, Mainframe Performance Consultant, zChampion Worldwide Banking Center of Excellence, IBM +44-7802-245-584 email: martin_pac...@uk.ibm.com Twitter / Facebook IDs: MartinPacker Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.

Progress Indicator For AMATERSE?
When I receive data from a customer I pull it using FTP - and I get a line in the SYSOUT every so often, as well as an early file size line to compare against. My next step is to unterse it. I think it would be useful to have a similar progress indicator. Do others agree? Or is this a very minor nice to have? (My thinking is a progress indicator for terse WOULD be useful to customers.)

Re: Rexx question - Dynamic generation of variables?
Not to dismiss the sample at all but... ... this really shows off the grottiness of Classic REXX as a language... I have incantations just like these (and knowing enough of object-oriented languages and Object REXX) I wonder why we haven't ported Open Object Rexx to z/OS yet... Most of this example would be MUCH better if implemented in Object REXX. For example alloc_member and alloc_dsname stems could be attributes/properties/members of a single object. (And increment and decrement operators wouldn't be a bad idea either - though in THIS case some form of collection class would probably be better.)
