Abstract
Loads on a plurality of computers are made uniform after a fail over, and resource competition is prevented. Loads of nodes (1 to 4) in a cluster (100) are obtained, taking-over information when a trouble occurs in one of the plurality of nodes (1 to 4) is generated beforehand based on the obtained loads, and the taking-over information is stored in a shared storage system (6) shared by the plurality of nodes. The plurality of nodes (1 to 4) monitor operation states of one another. When an occurrence of a trouble is detected, each of the nodes (1 to 4) in the cluster (100) excluding the troubled node reads the taking-over information from the shared storage system (6), and takes over a processing of the troubled node based on a trouble pattern and the taking-over information.
