Oracle Solution for Error ora-16637

ORA-16637: an instance failed to access the Data Guard broker configuration

What triggered the Error:

The broker could not access the broker configuration files on one or more database instances. This can happen when the DG_BROKER_CONFIG_FILE[1|2] initialization parameter values are not to the same set of file locations for a RAC database.

What should we do to fix it:

Shut off the broker by setting the DG_BROKER_START initialization parameter to false. Then set the DG_BROKER_CONFIG_FILE1 and DG_BROKER_CONFIG_FILE2 initialization parameters to file locations that are shared by all instances of a RAC database. Finally, restart the broker by setting the DG_BROKER_START initialization parameter to true.
