Hi Jon,
SQA will overflow into CSA if it gets to 100% and many shops size SQA and
ESQA to overflow deliberately. An 11M PVT seems pretty good to me too. I
can only manage 9M on most of my systems. Remember you get PVT in 1M chunks
so you would have to reduce common below the line enough to get up to 12M.

Subject: Consequences of lowering SQA spec
We are trying to fix a problem that one of our CICS regions has with going
short-on-storage below the 16MB line. (In the UDSA and CDSA pools, to be
exact.) As part of this effort, I am trying to expand the size of our
private area. (Insert your Viagra joke here.) At the moment, we have a
private area of 11240K, which seems pretty good to me, but I am considering
lowering our current specification of SQA in IEASYSxx from 10 to 6.
Our system seems to be maxing out at using about 36% of the space currently
allocated. What I need to know is what sort of problems I could be letting
myself in for if I lower the SQA allocation too much. Will I be up for a
week and then start having mysterious file problems or some such?
Thanks,
Jon
