If folks have lots of archives... look into the "convert archive" if you
look at my output below, I bet you can tell on what day we did a "convert
archive" to all our nodes.... but we do have a lot of archives... more
archives than backups

One thing I was recently informed of at a training class is that after
your database goes past the 40GB mark performance really starts hurting.
I bet this is the issue.
Anyways here are my stats.

Well now I'm a bit nervous. My scores seem to be as bad or worse than
Eric's. Is performance in this task basically a disk i/o, and cpu bound
task, or can other things factor in? Just a little confused since our
server isn't THAT slow (P4-2.8ghz). DB is sitting on mirrored 10K scsi
disks.

Hi *SM-ers!
Please help me with this and take the time to read this request!!!!
We're having serious performance problems with our TSM database. Part of
the discussion with IBM is how expiration should perform.
A technical document on the TSM website stated that one should be able
to expire 3.8 million objects per hour. As soon as I referred to this
document ("How to determine when disk tuning is needed") IBM removed it
from their site!!!!
Expiration runs at a speed of 140.000 objects per hour in my shop an I
know for sure that some of you are running at 3.8 million or more and I
like to prove this to IBM.
I'm begging for your help with this. I would like to ask you to issue
the following SQL statements on your TSM server(s) and send the output
directly to me:
select activity, cast ((end_time) as date) as "Date" ,(examined/cast
((end_time-start_time) seconds as decimal(18,13)) *3600) "Objects
Examined Up/Hr" from summary where activity='EXPIRATION' and days
(end_time) -days(start_time)=0
select pct_utilized, avail_space_mb from db
The first statement calculates your expiration performance
(objects/hour) and the second one lists your database size and
utilization.
Thank you VERY much for sending me your statistics in advance, I REALLY
appreciate it!!!
Kindest regards,
Eric van Loon
