You need to set accounting on, on the TSM server.
Once done, it will output session info to a csv file, which can then be
cross referenced against pre defined headers.

Re: [ADSM-L] Help! Trying to figure out what caused slow performance
Hi Ian,
The TSM client that's having issues was sending it's data to a disk pool
and not tape. The NIC's are set to 2GB on both. The TSM server was doing
approximately 6 NAS NDMP backups, 2 Admin Tape to Tape backup stgpool
copies and I believe there were approximately 6 TSM clients transferring
data at the same time. The environment was actually rather quiet and not
too much was going on. I was also wondering where/how I would get the
logs to show mediaw/idlew?
Just let me know. And thanks!

Re: Help! Trying to figure out what caused slow performance
The network transfer rate is very slow, are the NICs set to full duplex
and speed fixed or are they autonegotiating with the switch? What else is
passing through the TSM Server NICs at the time? Are the backups going to
disk or tape?What are those resourses doing at the time?
Also, can you get the line out of the accounting log to show mediaw/idlew
etc? This will break down the session duration into the waits...

[ADSM-L] Help! Trying to figure out what caused slow performance
Hello everyone,
I am getting hammered by my Oracle DBA's on slow performance at random
times on the TSM server. I have to admit that transferring 461 MB should
not take 36 minutes. I have looked in the activity log to see what was
running at that point in time and yes it was busy, but no more than usual
and immediately after this session ended this client no longer had slow
performance/issues transferring their data.
My TSM server is on AIX 5.3 and is at the 5.3.4.2 release. The client
listed below is a Solaris 5.8 server which has a TSM 5.2.2.0 client.
Any suggestions/help in determining what the cause of this might be would
be greatly appreciated!!!!!
