"Data Guard broker detected a mismatch in configuration ID"
*Cause: 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.
*Action: 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.
