The usual starting places...
Performing Query SEssion during the activity gives you a real-time look;
and performing 'netstat' on AIX allows you to gauge delay source.
Performing Query Node ... Format=Detailed right after the backup will
wait time values which help show where delays were occurring. Or you
look at the accounting records.
You don't indicate the nature of the backup. Whereas there were ANE
in the TSM server Activity Log, this should not have been an API-
type of backup, thus suggesting that either Oracle was shut down or
backup was "wild", and so standard issues affecting throughput
including file region locking; TSM storage pool speed, etc.). See
Performance Tuning Guide for many things to review. ADSM QuickFacts
numerous elements which can affect backup performance.
