ORA-00245: control file backup operation failed
DB version is 11gR2 RAC and during backup getting error as 'ORA-00245: control file backup operation failed' . The trace file generated during the failure also has the same information.
The snapshot control file is configured with shared storage only. After the error, if the backup is resubmitted then it completes normal
Completed: alter database backup controlfile to trace
ORA-00245: control file backup operation failed
after resubmitting
alter database backup controlfile to trace
Completed: alter database backup controlfile to trace
and now no error.
Can you please help to understand its behaviour.
Thank You,
