ORA-10469: error creating control file backup, no checkpoint

文档解释

ORA-10469: error creating control file backup, no checkpoint

Cause: The control file being backed up did not contain a valid control file checkpoint. Therefore the control file could not be backed up, as such a backup would 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 latter operation 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.
