For  to be highly available, the main components must be operational always. This is achieved by the failover processing. This section deals with the failover processing and the configuration settings for the high availability.

 to be highly available, the main components must be operational always. This is achieved by the failover processing. This section deals with the failover processing and the configuration settings for the high availability.
Failover is a backup operational mode available in a multi-server architecture. In failover, when a primary component becomes unavailable because of failure or scheduled down time, the secondary components assume the functions of the primary components. In
