ORA-16572: 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.
