"Data Guard configuration file not found"
*Cause: The Data Guard broker configuration file was either unavailable or
did not exist.
*Action: Verify that the configuration file was successfully created.
If the DG_BROKER_CONFIG_FILE[1|2] initialization parameters were
changed, ensure the file name on disk and the parameter value
match, there is space on the device, and the proper permissions
are granted. For a RAC database, ensure that these initialization
parameters are set to file locations that are shared by all
instances of the RAC database.
