Subsystem components

Systems can contain any combination of map components and subsystem components. A subsystem component is an Integration Flow Designer object that represents or references another system that you have already defined. The concept of a subsystem component is that it enables you to reuse a system. As such, a subsystem is an executable unit for which you can specify execution settings for using the Integration Flow Designer.

The Integration Flow Designer treats each subsystem component as a unique instance. Consequently, the name, execution settings, source and target interfaces, and document links are maintained separately with each subsystem component that you add to a system definition file.

The Integration Flow Designer displays a subsystem component graphically in the system window, as shown in the following diagram.

Subsystem components, which are displayed graphically in the system window, have four basic characteristics: name, execution settings (including sources and targets), and optional document links.
