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.
Peter,
Add a //ACCIGN DD DUMMY to your allocation and run JCL to bypass ACC/SRS
processing.
