CLUSTER SYSTEM, SERVER DEVICE, CLUSTER SYSTEM MANAGEMENT METHOD, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

A cluster system includes server apparatuses (10,20) connected by communication paths. Each server apparatus includes: a signal transmission unit (11) that transmits a signal indicating a self-presence to the other server apparatus via the communication paths (30-50); a reliability determination unit (12) that determines whether the communication paths (30-50) are reliable; and a processing management unit (13) that, in a state where the signal is not receivable from the other server apparatus, checks whether the communication paths to the other server apparatus have been determined to be reliable, and stops processing that is being executed when the result of the check shows that the communication paths have not been determined to be reliable.
