Steps to Troubleshoot:-

1.       Backup the existing user using Oracle exp.
exp userid=Dbusr/Dbusr file=DBOld_catalog.dmp

2.       Backup the dump file using NetBackup, set to permanent retention.

3.       Disable login for the original user.
sqlplus ‘/ as sysdba’
alter user DBusr account disable;

4.       Create a new user on the database, eg rmanuser

To create a New User :- 


1. Set up an Oracle database (with the user datafiles and listener).


2. Create a tablespace for the RMAN catalog (modify the path and instance name of the
RMAN catalog database where required):
SQL> create tablespace RMAN_TAB datafile
'D:\Oracle\Oradata\RCATP\TAB01\RMAN_TAB01.dbf' size 300m;
Tablespace created.

SQL>


3. Create the RMAN user as a schema owner for the RMAN tablespace.
SQL> create user rmanuser identified by rmanuser default
tablespace RMAN_TAB temporary tablespace TEMP;
User created.
SQL>


4. Grant unlimited quota to the RMAN user on the RMAN tablespace.
SQL> alter user rmanuser quota unlimited on RMAN_TAB;
User altered.
SQL>

5. Grant the recovery_catalog_owner permission.



SQL> grant recovery_catalog_owner to rmanuser;
Grant succeeded.
SQL>

6. Create the RMAN objects and schema.

D:\Oracle\Product\11.2.0\BIN>rman catalog rmanuser/rmanuser@rcatp

Recovery Manager: Release 11.2.0.1.0 - Production on Thu Jan 27

Copyright (c) 1982, 2009, Oracle and/or its affiliates. All
rights reserved.
connected to recovery catalog database

RMAN> create catalog;
recovery catalog created

RMAN>

5.       Register the target database to the catalog.
On DBOld database server:
su - oracle
DBOld
rman target / catalog DBNWusr/DBNWusr@(rman catalog instance)
register database;

To register a database

Connect into RMAN.

D:\Oracle\Product\11.2.0\BIN>rman target / catalog
rmanuser/rmanuser@rcatp

Recovery Manager: Release 11.2.0.1.0 - Production on Thu Jan 27

connected to target database: ORADB1P (DBID=2937678513)

connected to recovery catalog database

RMAN>

2. Register the target database with the catalog.

RMAN> register database;

database registered in recovery catalog

starting full resync of recovery catalog

full resync complete

RMAN>

3. You can also list out the RMAN parameters.
.


RMAN> show all;
RMAN configuration parameters for database with db_unique_name
ORADB1P are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP OFF; # default
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO
'%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO
BACKUPSET; # default
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; #
default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; #
default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE COMPRESSION ALGORITHM 'BASIC' AS OF RELEASE 'DEFAULT'
OPTIMIZE FOR LOAD TRUE ; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO

D:\ORACLE\PRODUCT\11.2.0\DATABASE\SNCFORADB1P.ORA'; # default

RMAN>


6.       Update all RMAN backup scripts to use the new username and password.

7.       Retry backup in NetBackup.
