| 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 that are in use by the new primary database. |
