(1) Overview

A cluster system is designed to achieve high availability (HA), and consists of an active server, which performs processing, and a standby server, which takes processing over when a failure occurs. This is called an active-standby configuration. This improves availability, since processing is carried over from the active server to the standby server when an error occurs, preventing operations from stopping. This operation of carrying over during a failure is called failover.

The software that controls an overall cluster system is called cluster software. Cluster software can monitor whether or not a system is operating normally, and perform failover when an error is detected, to prevent operation from stopping. The following figure gives an overview of a cluster system.

(2) Cluster system configuration

JP1/CSC - Manager and JP1/CSC - Agent can be run on an active-standby cluster system. By running these programs on a cluster system, procedures can be carried over from the active server to the standby server when a server failure occurs, allowing client security management to continue.

The following figure shows a configuration for running JP1/CSC - Manager and JP1/CSC - Agent on a cluster system.

Figure D-2 Example cluster system configuration

It is also possible to run only JP1/CSC - Manager or only JP1/CSC - Agent on a cluster system.
