Using RMAN to backup a 10.2 Oracle SAP database with TSM for ERP 6.3. It seems 
when TSM preempts a drive, it kills the corresponding RMAN channel. Sounds 
reasonable, but apparently RMAN continues with the remaining channel(s) to 
finish the backup, obviously taking a little longer. But the TSM for ERP 
program BRBACKUP, doesn't seem able to deal with that and falls over:

First, RMAN:

List of Backup Sets
===================

RMAN proceeds to list all the backupsets and, indeed, they are all there and 
backed up. But, apparently, because of the RMAN-03002 "error", BRBACKUP 
concludes there was a failure and ends the backup, reporting failure:

Recovery Manager complete.

Doesn't seem right to me. Is there a workaround (I know, I know, have enough 
tape drives), or is this PMR territory?
