| ERROR | 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. |
