Hi Everybody, I have one server using a 300Gb storage pool for its Oracle RMAN backups for one large database. After the backup is done, I want to do a backup storage pool to my offsite tape pool as quickly as possible by launching the backup stgpool command and the number of tape drives to use using the the following command : backup stg arc_disk arc_dr maxpr=4 After the command is executed, I see 4 processes inititated, but after about 5 minutes, only one process remains using one tape drive and the backup takes a long time for 300Gb ( 4 hours + ) . I know that the database backup is using 4 channels and there are about 16 files of 16Gb to 20Gb each in the ARC_DISK storage pool. Why does it always default to one process instead of multiple sessions as I initiate ? Server : AIX 4.3.3 , TSM 5.1.6 ( I know I know , old versions of both OS and TSM. The upgrades to AIX 5.2 and TSM 5.3 are currently in progress ). Rich Mochnaczewski
