13.3.8 Configuration for operation in a cluster system
JP1/IM supports cluster systems. When used in a cluster system, JP1/IM - Manager is failed over to the secondary node when a problem occurs on the primary node, and system monitoring continues without interruption.
An example of a system configuration for using JP1/IM - Manager in a cluster system is shown below.

In this configuration, there is a primary server and a secondary server.
JP1/IM - Manager executes on the primary server. The secondary server stands by in case a failure occurs on the primary server. In normal circumstances, JP1/IM - Manager on this server is in stopped state.
For details, see Chapter 7. Operation and Environment Configuration in a Cluster System (for Windows) or Chapter 8. Operation and Environment Configuration in a Cluster System (for UNIX) in the JP1/Integrated Management 2 - Manager Configuration Guide.

(1) Notes
-
When using JP1/IM in a cluster system, do not set up JP1/IM - Manager to restart after abnormal termination. If you need to restart JP1/IM - Manager, do so under the control of the cluster software.
-
When a process management process is activated on a logical host in a cluster configuration, if the logical host's conf folder does not contain an extended startup process definition file, the extended startup process definition file on the physical host is copied.
