We have a 112gb database that is 83% utilized and it only takes 30 minutes
to complete an expire inventory.
Either I have a real fast server or you have a real slow one!

Hi Rick

Our unload/reload what about 10 weeks ago and halved our database from 100Gb
for 50Gb... the database has grown by 20% since but expire inventory is
still much quicker than it was prior to the unload/reload, it is however
taking longer than immediately after the process...
definitely a worthwhile exercise.

Before 21 hours
Immediately after unload/reload 6 hours
Now 10 hours

It examines 21million objects..

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...!!!
