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.

Do you have any SQLRPG jobs running? There seems to be a bug in the optimizer that doesn't allow the pgm do reuse the ODP (for SQLRPG pgms created on older releasees), so a new ODP keeps on getting created for each iteration of the SQL statements. This is especially problematic if the optimizer decides that a copy of the file is the most efficient way of processing the file.

There is at least one APAR open addressing it, but IBM won't commit to fixing it quickly. This bug has actually delayed upgrading our production box from 5.1 to 5.2 and is wreaking havoc with our planning.
