RE: TSM TDPO Multiple Sessions

Hi,

I think this is actually normal. Netbackup does the same thing.
If you backup directly to tape with NB, each backuppiece is then also a 
separate backup job.

Subject: TSM TDPO Multiple Sessions


Hi,

We use RMAN to backup database to disk. And then use TSM TDP to backup RMAN 
backupsets from disk to TSM. Trouble is for each backup piece TDP is creating 
separate session to TSM. 

Has anyone else encountered this issue. There is obviously some over head in 
creating and releasing session to TSM for backup each RMAN backupset. I raised 
this issue with our TSM administrator, who in turn raised it with IBM. But IBM 
has not provided any sensible explanation for this.
