Abstract
A method for fault tolerant execution of an application program, in a server network having a first and second server, wherein the method includes: executing the application program in the first server; storing an object which represents the program in a cluster network database, wherein the object contains information pertaining to the program; detecting a failure of the first server; and executing the application program in the second server upon detection of the failure of the first server, in accordance with the information in the object. The information may include: a host server attribute which identifies which server is currently executing the program; a primary server attribute which identifies which server is primarily responsible for executing the program; and a backup server attribute which identifies which server is a backup server for executing the program if the primary server experiences a failure.
