Hi All,

On my database the datafile belonging to UNDO tablespace is corrupted, and that cause the database to be down automatically. For the recovery using RMAN I started the DB in mount and try to restore the UNDO tbs.
The restore process was successfull but I got ORA-19634 while recovering the tablespace.

The log is :

channel ORA_DISK_1: starting datafile backupset restore
channel ORA_DISK_1: specifying datafile(s) to restore from backup set
restoring datafile 00002 to /opt/oracle/oradata7/undotbs01.dbf
channel ORA_DISK_1: restored backup piece 1
piece handle=/opt/oracle/orabackup/XXXXX_XXXX_1.rmn tag=TAG20060612T130252 params=NULL
channel ORA_DISK_1: restore complete
Finished restore at 12-JUN-06

Starting recover at 12-JUN-06
using channel ORA_DISK_1

starting media recovery

RMAN-03002: failure of recover command at 06/12/2006 13:52:30

Please suggest.. I am using ORACLE 9.2.0.6.0

Thanks in advanced
