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.
Interesting!
Please, do the following
LISTCAT ENT(your.vsam.ksds) ALL and provide the output
check DATACLAS and it's definition from ISMF
check STORCLAS and it's definition from ISMF
I suspect DVC, but it's only wild guess.
