Abstract
A graphical user interface based method of configuring automatic failover from a primary database system to a standby database system that is coupled to the primary database system by a network. Also coupled to the network is an observer process that is independent of the database systems and that initiates the failover process. The observer periodically pings the database systems to determine whether a failover is necessary. The graphical user interface permits a user to specify the primary and secondary database systems, configure the observer, and specify conditions under which a failover may occur and to enable automatic failover. A failover context is created from the inputs to the GUI and stored in persistent storage belonging to the database systems. If the Observer's context is stale, the Observer fetches the database system's context.
