Subsystems 101 
Speaker: Chuck Stupca

This will be an introduction to subsystems on IBM i for those new to IBM i or for those needing a refresher course. We'll start with an overview of subsystems including the properties of a subsystem description. Then we'll compare the two default controlling subsystems, QBASE and QCTL and the different environments each starts up. The next step will be to understand workstation, autostart, job queue, and prestart entries. Finally we'll run through the creation of a subsystem to handle interactive work and talk about the advantages of distributing interactive work across multiple subsystems.

Learning Objectives:
  • Understand all aspects of a subsystem description and changes in i 5.4 to subsystems.
  • Determine if default subsystems need to be changed to meet IT needs.
  • Configure multiple subsystems to distribute interactive work dynamically.
