Overview

Every job executes in a subsystem. Therefore, the way in which subsystems are defined and used on your system greatly affects how your system performs.

This course describes how to manage the subsystems on your IBM i system. The course first presents the commands used to start and stop a subsystem. It then takes a detailed look at the contents of a subsystem description. You will see not only the attributes that define a subsystem, but also the contents of a routing entry and each type of work entry.

The course then shows different methods you can use to create a subsystem description. Next, you will see how to modify the attributes of a subsystem description and how to add, modify, and delete routing and work entries. The course ends by showing how to delete a subsystem description.

Approximate Study Time: 90 minutes
