John, Shouldn't you be looking at the sort manuals instead of SMS? How many sortwknn files are allocated is a function of the sort software not SMS.
Thank You, Dave O'Brien NIH Contractor ________________________________________ From: John McKown [joa...@swbell.net] Sent: Sunday, September 09, 2012 9:40 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Disk data set space allocation, philosophy I decided to ask this forum about a "problem" we have were I work. In summary, the programmers don't want to be forced to specify SPACE parameters in the JCL (or IDCAMS DEFINEs). They also don't want to be forced to use SORTWKnn allocations or do specify any SIZE type parameters in the controls. This latter works for JCL invoked DFSORTs. I have set the default so high that it can sort almost anything in the shop. I say "almost" because we had a job abend SE37-08 in an internal sort. My solution was to tell the person responsible for the job to change it to include about 30 SORTWKnn DD statements with SPACE=(CYL,(2000,100)). The only reason that I said so "over the top" was to be 99.9% sure that would be enough. But I will bet that the programmer will complain. They, basically, just want the system to handle space allocations. We do not have, and WILL NOT ACQUIRE any software such as SRS. We only use what is available with DFSMS and DFSORT. The previous storage administrator set up every DISK DATACLAS with a Dynamic Volume Count of 59, which is the max, and told the programmers to use SPACE=(CYL,(500,100)) for everything, unless they thought that they needed more. The tape DATACLAS is set up to make the default 190 tapes, instead of the "normal" 5, because "it would take too much work to make JCL changes". This latter I can understand because 90% of the work is putting in Change Control paperwork (no, this will not change). I have tried everything that I can think of to basically tell SMS to allow "unlimited" allocations. Have I missed some SMS parameter? Should I make all sequential data sets "extended format" so that they can have 123 extents per volume instead of only 16? Is there any negative to this? More CPU, slower I/O, anything? Does it work with DFSORT SORTWKnn DDs, the DFSORT manual seems to say that it does. If you noticed from previous messages, IT management is anti-z/OS so they basically just don't work to be bothered with it. Like because MS-Windows is such a POS that they need to concentrate on it. Makes me wonder why they adore it. -- John McKown Maranatha! <>< ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
