ORA-16626: failed to enable specified database
Cause:
This status was returned when attempting to enable a standby database that:
- Could not locate itself in The broker configuration file.
- Failed to distinguish itself from two or more databases in The configuration file.
- Determined it missed a role change within The configuration.
Action:
To correct the problem, try one of these actions:
- Confirm that the host and SID names for the database exactly match the values in the HOST_NAME and INSTANCE_NAME columns of V$INSTANCE.
- Confirm that there are not two or more databases with The same connect identifier. that is, multiple databases in The broker configuration should not reach The same database.
- If a failover had been performed and the old primary database has been re-created (or a standby database has been re-created), make sure the Data Guard broker configuration files have been removed for that database. Do NOT remove the configuration files
