Cluster system and an error recovery method thereof

摘要

A cluster system includes a transmission side server cluster consisting of a plurality of computers, one of which is selected as a transmitting computer and at least another one of which is selected as a standby computer. When the transmitting computer transmits a message it received to a receiving side server, it also transmits the message to the standby computer that was selected, based on load information for all computers other than the transmitting one in the transmission side server cluster.
