RE: Strange DASD Utilization Issue

["DebbieKelemen" <DebbieKelemen@xxxxxxxxxxx>]

Tom,

I guess my next step would be since we are 24x7 with the web would be to
figure out which subsystems I can end & bring back up without impacting the
web jobs.  And my guess is - it's the web jobs that are my biggest offenders
in this whole thing.  I just need a way to prove it to my IT Director on
paper so I can justify shutting things down for a few minutes.  Which is
what it really takes.

Deb

Debbie:

I not clear on why 5% temp storage would seem to be unusual. Without knowing
how "big" your system is and how it's used, there's no way to really guess;
but 5% is a reasonable amount.

With nothing else to go on, I'd say you're in great shape.

One minor note... A good part of "temporary storage" can be reclaimed
without an IPL. Simply ending and restarting your various subsystems will
handle a lot of it. That directly implies that the jobs in those subsystems
are also ended. As days go by, system server jobs, subsystem monitors, etc.,
have joblogs and other elements take little bits of storage temporarily.
When the jobs are ended, some of the stuff in temporary storage gets moved
into permanent storage, e.g., spooled joblogs, and other stuff is simply
deleted.
