Oracle DB backup script showing error

[Sushil_0488]

I am using NB 7.6.1 on RHEL 6.5 64-bit operating system hosted on IBM X3650M4 server.

This serve is used as Master as well as Media server. It is connected to IBM TS3100 tape using FC cable. (Direct connection)

Currently I am testing a Oracle DB backup script. The script is as attached.

When I ran the script, I see below error:

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of backup command on ch00 channel at 02/12/2016 20:02:29
ORA-19506: failed to create sequential file, name="orabk_NGMDB_20160212_15_1_903642274", parms=""

ORA-19511: Error received from media manager layer, error text:
   VxBSACreateObject: Failed with error:
   Server Status:  extended error status has been encountered, check logs
 

I am taking the backup directly on tape. I have already configured oracle lib on DB server (client)

$ ll $ORACLE_HOME/lib/libobk.so
 lrwxrwxrwx 1 ora112 dba 36 Feb  7 02:05 /opt/oracle/11.2.0/lib/libobk.so -> /usr/openv/netbackup/bin/libobk.so64
 

RMAN configuration for DB is as follows:

connected to target database: NGMDB (DBID=1958636150)
connected to recovery catalog database

RMAN>  show all;

RMAN configuration parameters for database with db_unique_name NGMDB are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default

CONFIGURE DEFAULT DEVICE TYPE TO 'SBT_TAPE';

 Any suggestions please?

I suggest you start with going through this post:

You have not told us anything about the client.

OS/NBU/Oracle versions (looks like Oracle 11g R2)?

Are normal filesystem backups working?

Have you confirmed and tested comms between client and master/media server?
Forward and reverse name lookup in both directions, port connectivity in both directions?

Have you created dbclient log folder on the client with 777 permissions?

Are you running the script directly from the client as oracle user?
Or script via NBU policy on the master?
If kicked off from the master, does the script have a section to check user id and 'su - <oracle-user>'?

Have you checked and confirmed that policy is configured correctly on the master?

Does the backup attempt appear in Activity Monitor?
What is the error in NBU?
