BE: The broker simplifies switchovers and failovers by allowing you to invoke them using a single key click in Oracle Enterprise Manager or a single command at the DGMGRL command-line interface (referred to in this documentation as manual failover). C: The broker coordinates database state transitions and update database properties dynamically with the broker recording the changes in a broker configuration file that includes profiles of all the databases in the configuration. The broker propagates the changes to all databases in the configuration and their server parameter files. References: https://docs.oracle.com/cd/E11882_01/server.112/e40771/concepts.ht
