What problems are you attempting to solve by enforcing this? - -teD - Original Message From: Farley, Peter x23353 Sent: Wednesday, September 30, 2015 12:25 To: IBM-MAIN@LISTSERV.UA.EDU Reply To: IBM Mainframe Discussion List Subject: How to limit tiny SMS-managed VSAM KSDS to one volume?
I need some advice from storage gurus. I need to make a tiny SMS-managed VSAM KSDS that will NOT extend, neither to secondary space on the first volume nor to secondary volumes. I need to test some error logic in an application program and I need a "file full" or "no more space" condition to test it. I have these parameters in the define cluster command: VOLUME(*) CYL (1 0) But when I try to fill up that file with IDCAMS REPRO so that there is no more room for any records by copying from a similar file with many records into the tiny one, it automatically extends to new volumes, with messages like this: SMS4000I TSOUSERZ, MKTSTFIL, SYS00001, ATTEMPTING SPACVOLA FOR TSOUSER. TINY.DATA, XXXXXX, 1 SMS4400I VOLUME ADDED - OLD VOLUME XXXXXX, NEW VOLUME SMS . VOLUME COUNT IS 2 I assume this is due to some hidden parameter in the STORCLAS that overrides my specification of only one candidate volume. My question is, how do I override that hidden STORCLAS parameter to force a no-more-space error here? I deliberately want the attempt to add one more record to force an error. I do NOT have easy access to a storage admin on this system, so I need help from you. ISMF is not available in my TSO menus, so I cannot check the STORCLAS for myself. TIA for any help you can offer.
