2.2.3 Example of a system configuration for creating a cluster system
A cluster system comprises multiple server systems linked to operate as a single system. Two servers with the same environment are set, and if a fault occurs in the server that executes work tasks (the primary node system) the processing is passed to another server (the secondary node server) and the work task is continued.
The following figure shows an example of a system configuration for creating a cluster system.

When you are considering which system configuration to use for cluster operation, note that logical host names in FQDN format cannot be used in a cluster system.
For details about the setup for using a cluster system, see 8. Setup for Operation in a Cluster System in the Job Management Partner 1/Automatic Job Management System 3 Configuration Guide 1 (for Windows hosts), or 17. Setup for Operation in a Cluster System in the Job Management Partner 1/Automatic Job Management System 3 Configuration Guide 1 (for UNIX hosts).
For details about operating a cluster system, see 11. Operation in a Cluster System in the Job Management Partner 1/Automatic Job Management System 3 Administration Guide.
