Did you notice a performance improvement after the reorg.  If you did,
is it still performing better since it has grown?

Thanks

Rick

It is different from DBBackup - there are specific load/unload abilities
in TSM. The process results in the DB being re-orged. We recently went
through the process and approximatley halved  the size of our 120GB DB,
the gain is fairly short lived though. The re-org was around 8 weeks ago
and the DB is back up to 80% of its original size.

unload / load? you mean backup then restore. will that reorg the db?

30 GB is not outrageously large. I've worked with one
that was almost twice that size. You can unload and
load the database or perhaps do an audit on it.
There's an entire section called utilities in the
Admin Reference. Be forewarned that an audit could
take days if not weeks...!!!
