RMAN control file backup failure

[anishC5]

Hello all,

We are observing a strange scenario. For the RMAN backup, we are not seeing any failures at NBU end, but the DBA's are getting the following alert:

RMAN-00571: ===========================================================

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-00571: ===========================================================

RMAN-03009: failure of Control File and SPFILE Autobackup command on ch01 channel at 06/13/2015 13:32:24

ORA-19506: failed to create sequential file, name="c-2981266559-20150613-00", parms=""

ORA-19511: Error received from media manager layer, error text:

   Failed to remove, c-2981266559-20150613-00, from image catalog

Please can you guide me for which logs to check to unerstand the error and how to resolve this?

i am not getting any error at NBU end.

NBU master-Appliance 5230: 7.6.0.2

NBU media-Appliance 5230: 7.6.0.2

Client: LINUX red hat 5.6: 7.6.0.2

i have been looking for hints on all oracle and NBU forums and articles but not a clue.

Anish

How I have handled database backup troubleshooting:

Without more knowledge my guess is a timeout because the control/spfile backup is waiting in the netbackup queue

Get DBA to check if they are running/configured delete command for RMAN catalog, if so please stop deleting from RMAN catalog. Let Netbackup expire RMAN related NBU images based on NBU Oracle policy.

Or

Please get DBA to change AUTOBACKUP to OFF and then try another backup.
