ORA-16626: failed to enable specified object

Cause:     The broker failed to enable management of an object (most likely a standby database). You can expect to see this status when attempting to enable broker management of a standby database that:

- cannot locate itself in the broker configuration file.

- fails to distinguish itself from two or more databases in the configuration file.

- determines it was not part of a change of primary database due to failover.

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 you have not created two or more databases with the same connect identifier. That is, multiple databases in the broker configuration should not indicate the same physical database.

- if you had performed a failover and have re-created your old primary database (or a standby database that had to be 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.
