4.2.5 Starting multiple instances of the JP1/AJS3 services

The JP1/AJS3 services of JP1/AJS3 - Manager and JP1/AJS3 - Agent can be started as multiple instances in a single host, enabling operation in a cluster environment. To start multiple instances of the JP1/AJS3 services, define logical hosts that will allow the physical host to be used as multiple virtual hosts, and then set up the environment for services to start on a logical host basis.

To start multiple JP1/AJS3 services on a logical host basis, set up the environment for each logical host. Prepare sufficient system resources (semaphores, virtual memory, shared memory, disk space, and so on) for the number of instances of the JP1/AJS3 services that will be activated simultaneously.

The following figure shows the system operation with multiple instances of the JP1/AJS3 service.
