[ADSM-L] Slow TSM DB Backup
We are experiencing slow TSM DB backup process on both of our TSM systems using
AIX V6.1.7.x, TSM V220.127.116.11, Atape v18.104.22.168. The issues began immediately
after we upgraded from AIX v22.214.171.124 to AIX v6.1.7.x. We have created a
performance PMR#53387,379,000 with TSM support. With 100GB data in a DB2
database, we are seeing 30 to 60sec waits between .1/.2GB database transfers to
IBM LTO4 tape drives via TSM q se screen. It is taking a very long time to
complete a TSM DB backup. Before the AIX upgrade, the full DB backup took about
10 minutes; now we are seeing backups of hours in length.
Anybody having these types of issues??
