Posted by Mawahid in

Problem Description:

While duplicating database using RMAN it fails with ORA-01092: "ORACLE instance terminated. Disconnection forced" and ora-03113 error reported.
RMAN-00601: fatal error in recovery manager
RMAN-03004: fatal error during execution of command
RMAN-10039: error encountered while polling for RPC completion on channel clone_default
RMAN-10006: error running SQL statement: select act from x$ksusex where sid=:1 and serial=:2
RMAN-10002: ORACLE error: ORA-03113: end-of-file on communication channel
RMAN-03002: failure of Duplicate Db command at 02/30/2010 01:21:18
RMAN-03015: error occurred in stored script Memory Script
RMAN-06136: ORACLE error from auxiliary database:
ORA-01092: ORACLE instance terminated. Disconnection forced
If we look for the auxiliary database alert.log file then it shows that Undo Tablespace 'UNDOTBS1' does not exist or of wrong type.

Cause of the Problem
The UNDO_TABLESPACE parameter of auxiliary database is not same as target database. In the source database undo tablespace is set to UNDOTBS2 while in target database undo tablespace is set to UNDOTBS1. The undo tablespace specified in the auxiliary database parameter file does not exist.

Solution of the Problem
Make sure that the undo tablespace for auxiliary database is same as of target database.
Edit the init.ora or alter the UNDO_TABLESPACE parameter of the auxiliary instance and set
undo_tablespace = UNDOTBS2
- restart the auxiliary instance in nomount mode and repeat the duplicate database command.
