My TSM 6.2.3.0 DB backups on AIX have increased in elapsed time from a little over an hour to almost four hours. I am at AIX 6.1.7.1 but I can't say for sure that the increase in backup times corresponds to the time that I did the AIX maintenance.

We are experiencing slow TSM DB backup process on both of our TSM systems using AIX V6.1.7.x, TSM V6.2.3.100, Atape v12.4.1.0. The issues began immediately after we upgraded from AIX v5.3.12.3 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??
