Subsystem description

 

A subsystem description is a system object that contains information defining the characteristics of an operating environment controlled by the system. The system-recognized identifier for the object type is *SBSD. A subsystem description defines how, where, and how much work enters a subsystem, and which resources the subsystem uses to perform the work. An active subsystem takes on the simple name of the subsystem description.

Like a set of detailed blueprints, each subsystem description is unique, containing the specific characteristics that describe the subsystem. The description includes where work can enter the subsystem, how much work the subsystem can handle, how much main storage (memory) will be used, and how quickly jobs in the subsystem can run.

You can use a subsystem description supplied with your system (with or without making changes to it), or you can create your own.
