I recommend to ugrade to latest maintenance level for your version 4.2.2.0
(Because 800MB of TSM usage is very very abnormal
One of my TSM servers work with 128MB RAM on AIX)
Second, you should do a unload / load db definitely. It will decrease your
utilization percentage

Subject: Expiration performance problem
Hi all,
Env: TSM server 4.2.0.0 on MVS 2.9
Database 20GB, 66% utilized, 8 volumes on HP512 (4x ESCON connected)
In last two months expiration process dramaticaly slowed down to approx
500-1000 objects/minute. Expipration of 100.000 objects takes 3-4 hours (no
other TSM processes runs at a time, TSM have about 800MB memory allocateed).
Compared to our other TSM environments it is very slow. DB grows from 10GB
to 20GB in last 2-3 months.
Any idea? Tune some parameters? Increase memory allocation? Or any ather
action like unload/load DB?
Any help will be appreciated.
Tom
