Thanks for the info, Charles - we will try that. Not ready for 5.3 yet.

We say the same issue with versions 5.1.7.3 / 5.2.3. *Some 4.1 versions) Now @ 5.2.3.5 and a 150GB DB takes about 45min... It use to take hours....

That is very weird. Whenever I've been waiting (in a panic, of course) for TSM to restart, first thing I do is turn on iostat; I know that as long as the I/O is running like crazy, TSM is still processing its log. Once the I/O stops, TSM is back up. Have never just seen it sit and spin CPU like that. And 35GB isn't very big, really. If on a normal day your DB cache hit ratio is OK, I have no idea what could be causing this. I would ping very hard on Tivoli to get an answer, and keep raising the priority on the problem until you get one. 10 hours to restart is a SERIOUS availability problem!

Yes, thats about 600MB. Expiration doesnt run too badly. Expspeed says we are doing about 2M pages per second. It seems like TSM grabs one CPU, runs it at 100%, and very little I/O is occurring during all this time. The DB is 90.3% of 35000MB, and the DB was reorged about 3 months ago.

Wow. I thought 20 minutes was a long restart time!. Never heard of anything that bad before.
How big is your DB? Does your expirarion take a really long time to run?
You are only applying about 600 MB of updates, yes?

Wehave had a problem over the years with LONG TSM restart times if the recovery log has anything in it. Here is what we are running:
AIX 5.1 ML4+ Running on a P670, 4 Proc, 16GB Memory TSM 5.2.1.1
We had an outage on one of our TSM instances Friday. The log is currently in normal mode, 12GB in size. It was 5.1% full. The
restart
took 10 hours!. I have noticed this with various releases of TSM, so this is not new. I talked to TSM about it before, and did not get any good answers. Has anyone else seen anything like this? Would Roll Forward DB mode help? Thanks for any info.
