<p><P>PROBLEM TO BE SOLVED: To provide a cluster system, cluster server and cluster control method detecting a business application in which a failure has occurred, without having to use a system information management table in a split brain state where communication performing heartbeat processing goes dead. <P>SOLUTION: The cluster system comprises a plurality of servers connected by a network, wherein each application is processed by a server of an active system, and when the application becomes abnormal, application in an abnormal state is processed by a server of a standby system. Each server has a heartbeat-monitoring part for detecting whether another server is in a normal state; an application control part for starting an application operating in the other server, when heartbeat with the other server is abnormal; and an application switching part for changing a MAC (Media Access Control) address corresponding to an IP address of an application of a router to own MAC address. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
