Re: TSM TDPO Multiple Sessions

Do you have/are you actually using TDPO (Tivoli Data Protection for Oracle) or just TDP? How big is your DB? Do you have LANFree licensed? If you've actually got TDPO, why don't you just go directly to tape? Alternatively, define a disk storage pool within TSM, use RMAN/TDPO to send the backups to that disk, then let TSM handle migrating that to tape?
