Re: VLF Caching
I had thought (from https://www.ibm.com/developerworks/community/blogs/MartinPacker/entry/lla_and_measuring_its_use?lang=en ) that the SMF records did not really tell us very much about the tuning. But it could have been that I didn't really understand them So we used the healthcheck iteratively to watch the trimmed age of the exceptions, and arrived at 64Mb. At 4MB the trimmed age was 1 day, at 32MB 11 days, at 48MB 30 days. At 64MB all our sysplexes seem not to be trimming within 60 days any more. That was a while ago, and we are just starting to look at the IGGCAS class which has also been tripping the healthcheck exception (at 1 day).

In the distant past some found that sizes of 256M and above were detrimental. But no one that I know of actually did any analysis to try to figure out why. The guess was that the performance decrease correlated to the number of objects that then were cached.

Peter Relson z/OS Core Technology Design SNIPPAGE Thank you. I can tell you that 16MB is TOO SMALL. And so far, in our shop, 32MB is too small. The diminishing returns problem is going to be interesting to find. I know that you want to cache hi-use modules. But, if the module is beyond a certain size, you may not want to cache it - DASD fetch may be better. So, if you have sufficient cache, you can get all of your stuff in there w/o hitting the 10% headroom issue. And if the speed of XMEM is hi enough (based on CPU avail)... But, if cache is being used by all large modules, you can get into a cache thrash situation (old APAR/PTF for where it would loop) -- Fastest way I know to get the situation (it can be done with a mix...). We have noticed that at 16MB, we BURN MSUs in VLF TRIM (sorry, forgot the module name). So another aspect of tuning is setting the time lower to get things to be trim-able sooner. But, that can have diminishing returns So it may need to be set higher (sigh). Enter the EXITs. Now you have to have someone in your shop that knows ALC and management can give clear guidance to rules so they can be effected... (sigh). How about IBM and CA play nice and get CA the right stuff so they can fix PMO and QuickFetch for PDSEs (I can't believe I'm writing this!!).

Re: Sort to show differences in a 2-file match
Hi Billy, Typically for the first (records in B, not in A), I do the same sort of thing including A in the sortin concatenation twice, and B once, thus getting rid of all duplicate records by discarding all of A and the matches in B (based on full record length). For the records in A with matching keys to B but different data, that seems trickier. Firstly you want to discard all the A records with unique keys by concatenating A ahead of B in sortin , and using FIRSTDUP (and keylength only) to select only the A records which match B keywise. Then a third step to take that output concatenated ahead of B, with the NODUPS option (based on full record length). Then finally concatenate the third step output with the first step output. ... at least I think that meets your new objective ...

Re: ACS routine imbed/include function?
Hi, What we do to get around this is to use ISPF skeletons (with a bit of REXX involved) which we run as part of a two stop batch process using Naviquest. Within the REXX, we build a table of our DB2 systems, and then the skeleton has )DOT constructions to loop around building those 15 WHEN clauses in a standard way. The first step works out the next suffix for the routine, builds it into a work dataset, and sure SUPERC to compare to the existing (current) routine (which we review to make sure there is no unexpected change). Having reviewed that, the next step copies into the production ACS routines dataset, and does the translate and validate. The activation is then done manually after the two jobs are run. We don't really have local content, although there are a little extra )SEL type inclusions by sysplex in the infrastructure part of the skeleton (the ACS code is thus in some way standard across all our life-cycle sysplexes).
