ORA-10469: error creating control file backup, no checkpoint ORACLE 报错 故障修复 远程处理
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.
