ABSTRACT:
A system and method for enabling failover in an application server cluster. A “primary” application server computer in the cluster may provide a service or data necessary for other application server computers in the cluster to operate. In addition to the primary application server computer, one or more of the other application server computers may be designated as “backup” application server computers. Each backup application server may backup the processing information managed by the primary application server. When the primary application server itself becomes unavailable (e.g., due to a failure of the computer system or network), one or more of the backup application servers may be promoted to the role of primary application server.
