Title:
CLUSTER SYSTEM, CLUSTER SYSTEM CONTROL METHOD, SERVER DEVICE, CONTROL METHOD, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM HAVING PROGRAM STORED THEREIN
Document Type and Number:
WIPO Patent Application WO/2019/049433
Kind Code:
A1
Abstract:
The present invention reliably determines as to whether or not a service is properly provided to a client by an active-system server. A cluster system (1) is provided with: an active-system server (2) for providing a prescribed service to a client device via a network (4); and a standby-system server (3) which, in the event that a fault occurs in the active-system server (2), provides the prescribed service to the client device in place of the active-system server (2). The standby-system server (3) has a monitoring unit (6) that accesses, via a network (4), the prescribed service provided by the active-system server (2), and monitors whether or not the service can be accessed correctly. The active-system server (2) has a cluster control unit (5) that implements failover in the case when the monitoring unit (6) of the standby-system server (3) has determined that the prescribed service provided by the active-system server (2) cannot be accessed correctly.
