Oracle Error Message
ORA-16603: Data Guard broker detected a mismatch in configuration ID
Reason for the Error
There was a mismatch in configuration unique ID. This could occur if the original configuration was re-created while this database was disconnected from the network or the same database was added to two different Data Guard broker configurations.
Solution
Make sure the database belongs to only one broker configuration. Shut down the broker by setting the DG_BROKER_START initialization parameter to false. Then remove the Data Guard broker configuration files. Finally restart the broker by setting the DG_BROKER_START initialization parameter to true.
