Describes which system-supplied subsystems are used for each of the server functions. These topics also detail how the subsystem descriptions relate to the server jobs. Learn about i5/OS™ subsystems and how to autostart and prestart jobs.
A subsystem description defines how, where, and how much work enters a subsystem, and which resources the subsystem uses to do the work.
Autostart jobs perform one-time initialization or do repetitive work that is associated with a particular subsystem. The autostart jobs associated with a particular subsystem are automatically started each time the subsystem is started.
