I know this has been discussed, but I see nothing that pertains to my issue. I have an Oracle node allowed 6 mountpoints. It backs up LANFree using 5 RMAN channels, i.e. 5 tape drives.
Now we are restoring, allocating 4 RMAN channels. It is only using one. It is a 5TB DB and has been running the restore for 18+ hours, never using more than one drive (channel "t1" in RMAN). I see many tapes mounting/dismounting/remounting, etc., using different tape drives, so the data is definitely spread out over many tapes, but it will NOT use more than any one tape at any one time. I see 4 drives with tapes in them, but Q MOUNT always shows only one of them "IN USE" while 3 are always "IDLE" because RMAN is not using multiple channels even though the RMAN script has 4 allocated.
Based on all of this, is there anything else that needs to be checked? Is this all on the Oracle RMAN side? Anything that you know of that the DBA could do there? (either now during the restore, or for future restores?)
