Hellow! Sorry for invading your thread. I have a slightly different question on delete obsolete. If you put your backups on tape using DataProtector as a media agent. Which maintainance steps you need to perform on RMAN catalog? And when deleting obsolete backup sets do you need to open a channell to the right tapes or is it enought just to connect to the rman catalog. Regards, Luka -- //www.freelists.org/webpage/oracle-l
