How to fix the Error ORA-16626: failed to enable specified database ?

You can fix this error in Oracle by following the below steps

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 that are in use by the new primary database.
