RE: something using up DASD

[rob@xxxxxxxxx]

If you are going to run RTVDSKINF you might as well run it in a single 
string job queue and run
PRTDSKINF RPTTYPE(*SYS)
in the same job queue.  It's a small summary report.

While queries on the files generated by RTVDSKINF are useful, to assume 
that the problem are with traditional DB2 files, journals, etc is a big 
mistake.  Our IFS objects make our DB2 objects look puny.

Besides, if it's in some really esoteric object then that is more likely 
to show up on the *SYS report.

You could get really weird.  Let's say you have some paging software that 
acts upon a message in a message queue.  Then just create the message 
queue QSYS/QSYSMSG.  Change your threshold down to some safe percentage, 
like 80%.  When that is exceeded, and your software catches the message in 
QSYSMSG then it can act upon it.
If you page, then don't use email.  Use a modem instead.  Exceeding 
threshold has a tendency to shutdown some tasks and I believe email is 
one.

RE: something using up DASD






I had a similar situation on our 820 with 120G of DASD where overnight 1G 
or
so would be used up and I could not trace it down.  I finally solved it by
running RTVDSKINF on daily at 2:00 a.m., along with a query (scheduled
several hours later) that lists ALL OBJECTS over 100mb sorted by size.
RTVDSKINF creates a file, QAEZDISK, over which the query runs.

This procedure is very useful if ran daily as indicated.  The culprit in 
my
case turned out to be an object called *INTSYSJRN.  This object can grow
really fast overnight.  It's less than a MB today but was over 1.2G just
last week.
 
For what it's worth, below is a snip from my query of QAEZDISK that ran 
this
morning.

Subject: something using up DASD


Since we upgraded our operating system from V4R5 to V5R2.........our DASD
used keeps on climbing.  Can anyone tell me where to look for files that 
the
system maybe using that can be cleared?  Is there something running that 
we
do not need to be running that is using up disk space?  This is on an
ISeries 730, we have 154.6G of DASD and currently 92.2575 % is used up.
This machine is our development machine we only do programming mods and
changes on this machine with some users doing some testing.  This machine 
is
almost a mirror of our production machine for data. When we left on Friday
it was just under 90 % and I has increased from 91.0118 % this morning. 
Any
help anyone can give on where to look would be greatly appreciated.

TIA
