ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error below

Oracle Error Code: ORA-01547

Cause: Media recovery with one of the incomplete recovery options ended without error. However, if the ALTER DATABASE OPEN RESETLOGS command were attempted now, it would fail with the specified error. The most likely cause of this error is forgetting to restore one or more datafiles from a sufficiently old backup before executing the incomplete recovery.

Action: Rerun the incomplete media recovery using different datafile backups, a different control file, or different stop criteria.
