Understanding JD Edwards EnterpriseOne Subsystems

Within JD Edwards EnterpriseOne, subsystems are defined as continuously running batch jobs that run independently of, and asynchronously with, JD Edwards EnterpriseOne applications. Subsystem jobs function within the logical process of the operating system or the queue defined for the server platform. You can configure JD Edwards EnterpriseOne to use one or more subsystems.

The term subsystem is an industry-wide generic term that usually indicates a system that is a sub-process to an operating system. On IBM i server platforms, a subsystem is a logical process that is used to run system jobs, whether they are JD Edwards EnterpriseOne or other application jobs. For UNIX, JD Edwards EnterpriseOne subsystem is functionally equivalent to a daemon. On UNIX and Windows server platforms, system jobs are processed in queues; these queues are functionally equivalent to subsystems on the IBM i platform.
