This section describes JP1/IM - Manager operation in a cluster system, starting with an overview of cluster systems through an explanation of JP1/IM - Manager functions in a cluster system.
To apply cluster operation to JP1/IM - Manager, you must run both JP1/IM - Manager and JP1/Base in the same logical host environment.
For details about cluster operation in JP1/Base, see the description of settings for cluster system operation in the JP1/Base User's Guide.
This section focuses on using a cluster system to achieve high availability (HA). This section does not describe use of a cluster system for such purposes as evening out load distribution.
