JP1 Version 12 JP1/Automatic Job Management System 3 System Design (Configuration) Guide


2.2.2 Examples of manager/agent system configurations

Jobs can be distributed among multiple hosts. Install JP1/AJS3 - Manager on the hosts on which jobs will be managed (one or more manager hosts) and JP1/AJS3 - Agent on the hosts on which the jobs will be executed (agent hosts). JP1/AJS3 - Manager can be used instead of JP1/AJS3 - Agent. Install JP1/AJS3 - View on the hosts that will perform job monitoring.

Organization of this subsection

(1) Operation with a single manager host

Install JP1/AJS3 - Manager on the manager host, and JP1/AJS3 - Agent on the agent hosts. Set up a dedicated JP1/AJS3 - View host as required.

The following figure shows an example of a manager/agent system configuration with one manager host.

(2) Operation with multiple manager hosts

Prepare multiple hosts on which to install JP1/AJS3 - Manager, and multiple hosts on which to install JP1/AJS3 - Agent. Set up a dedicated JP1/AJS3 - View host as required.

The following figure shows an example of a manager/agent system configuration with multiple manager hosts.

Use JP1/AJS3 in an environment where the IP address can be resolved from the local host name. JP1/AJS3 can only operate in an environment where the IP address can be resolved from the local host name.

When executing jobs on multiple agent hosts, you must also specify settings that allow resolution of the IP addresses for the manager hosts, agent hosts, and the hosts in other systems. When DNS is used, specify settings that allow resolution of host names in the FQDN format. Note, however, that host names in the FQDN format cannot be used for logical host names.

(3) Using a single agent host as multiple execution hosts

To execute jobs in JP1/AJS3, you must register agent host information in the manager host. The required information consists of the execution agent (the logical name of the agent host), together with its physical host name.

By creating multiple execution agents (logical names) for a single agent host, you can set up a job execution environment in which a single agent host can be used as multiple execution hosts. For details, see 2.5 Setting the job execution environment.

(4) Notes on manager/agent system configurations

Some cautions on manager/agent configurations are listed below.
