The rman log just says something unexpected happened, so first we need to find the specific error by checking the alert files of both the catalog and target database for a db error and check the netbackup logs for a specific media error.

Subject: RMAN duplicate is failing : database session for channel <channel_name> terminated unexpectedly

Hello all,

I am trying to duplicate a 3TB database, which has 927 datafiles. It is failing with the following error. Some of the google notes refers me to work with the backup media vendor. I have contacted Netbackup vendor Symantec but has not got a solution yet and wondering if anyone from this list experienced similar problem and have some recommendations. Database version: 10.2.0.4
Netbackup client for Oracle: NetBackup-Solaris10 6.5.5 OS: Sun Solaris 10.

Channel aux4: reading from backup piece
/incr0_TWDMAS_365890_776372926_a2n4d0lu

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of Duplicate Db command at 03/19/2012 09:50:58

RMAN-03015: error occurred in stored script Memory Script RMAN-10038: database session for channel aux1 terminated unexpectedly

BTW: I am able to duplicate many other databases (all smaller than this problematic one) to the same UNIX server without any problem. Not sure if the size or the high number datafiles in backup is causing any issue or not.

Thanks,
Ashoke Mandal
