For Linux, to ensure that configuration files are synchronized between the Active and Standby locations, set up passwordless access between the hosts on Location A and Location B. This way, all file changes made for components on the Active location are propagated to the Standby location. An additional advantage is that you only need to perform configuration changes once. Passwordless communication is also used for the Failover Manager copy actions which keep Active and Standby /local directories synchronized.
If you plan to run the Failover Manager on a separate dedicated host, you need to set up passwordless communications between the Failover Manager host and between Standby and Active locations.
