ORA-10469
Error creating control file backup, no checkpoint
Cause
The control file being backed up does not contain a valid control file checkpoint. Therefore, the control file cannot be backed up because the backup will not be usable later for recovery. A common cause for this situation is that you executed CREATE CONTROLFILE, which mounts the database, but not ALTER DATABASE OPEN, to open the database. The ALTER DATABASE OPEN generates a valid control file checkpoint.
Action
Open the database with ALTER DATABASE OPEN, which results in a valid control file checkpoint. Run the backup operation again.
