Oracle Database Errors or Warnings from Error ORA-16431 to ORA-16507


ORA-16431: Cannot expand control file
Cause: More threads were added on the primary database after this standby control file was created.
Action: Shut down the standby database, either replace the control file with a new standby control file from primary database or change the COMPATIBLE parameter to 10.2.0 or above, and restart the standby database.
ORA-16432: inconsistent set of terminal logs detected
Cause: Media Recovery stopped because it detected an inconsistency between the first log in the new incarnation and the state of the previous incarnation. If this database is a bystander standby database, this is most likely because there was a failover operation, and this database applied terminal logs generated from that failover operation for some redo threads but applied corresponding logs from the old primary database of that failover operation for some other redo threads.
Action: Flashback or restore this database to before the standby_became_primary_scn of that failover operation and restart media recovery. The standby_became_primary_scn of the failover operation can be obtained from V$DATABASE on the new primary.
ORA-16433: The database has not been opened in read-write mode
Cause: When a physical standby database is converted to a read-write database or there was a failed open resetlogs attempt, the database should be opened in read-write mode to have correct file access information in the controlfile.
Action: Open the database in read-write mode and reissue the command.

ORA-16438: Switchover to primary cannot be executed at this time
Cause: ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY could not be executed because an incompatible operation such as RMAN restore or flashback was in progress. See the database alert log for details.
Action: Wait for the incompatible operation to complete. The files that have been flashed back or restored need recovery before you can reissue ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY statement. Start redo apply and verify that the SWITCHOVER_STATUS column of the V$DATABASE view reports TO_PRIMARY or SESSIONS_ACTIVE before retrying ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY.
ORA-16501: the Data Guard broker operation failed
Cause: The Data Guard broker operation failed.
Action: See accompanying messages for details.
ORA-16502: the Data Guard broker operation succeeded with warnings
Cause: The Data Guard broker operation succeeded with warnings.
Action: See accompanying messages for details.

ORA-16504: the Data Guard configuration already exists
Cause: A request to create a Data Guard configuration was made while connected to a database that is part of an existing configuration.
Action: To create a new configuration, the existing configuration must be deleted.
ORA-16505: site ID is invalid
Cause: The request contained an invalid site ID.
Action: Make the request again with a valid site ID.
ORA-16506: out of memory
Cause: Process exceeded private or shared memory limits.
Action: Check for memory leaks, increase system parameters and restart.
ORA-16507: unrecognized request identifier
Cause: The specified request identifier was not recognized by the Data Guard broker.
Action: Reissue the request using a valid request identifier.
