Abstract
A node (, FIG.), within a networked computer system (), is capable of supporting communications with other nodes relating to operating multiple application instances in a master-slave configuration. Each node periodically generates and sends (, FIG.) a Heartbeat message (FIG.) that indicates the operational status for one or more application instances being managed by the node. When a node receives a Heartbeat message from a remote node, it evaluates (FIG.) the Heartbeat information for each application instance reported in the message, and takes any appropriate actions. The node also determines (, FIG.) whether new configuration information should be obtained for each of the application instances the node is managing, and requests (, FIG.) that new configuration information, when necessary.
