I've never had any performance problems with AIX while the DB backup was 
running, however I think you should apply maintenance to your AIX level.  IBM 
has never been fond on running levels of AIX with no maintenance applied.

Subject: [ADSM-L] DB Backup to tape affect AIX Performance

 

Hello all,

 

Anyone have AIX performance problems when a TSM DB backup are running?

 

I have been some performance problems on my AIX Server.

 

I detect some I/O high level and disk group busy level on rootvg Volume
Group (TSM installation path) when the TSM DB Backup are running.

 

The DB Volumes and Logs are on a different Volumegroup.

 

Anyone have this problem?

 

TSM Administrative Scheduler command: backup db t=f devc=l43tap10 vol=501ABE

 

AIX level: 5.2.0.0

TSM: Version 5, Release 2, Level 3.4

Cumprimentos / Best Regards / Mit freundlichem Gruß
