Chapter 7 - Subsystem Components
Systems can contain any combination of map components and subsystem
components. This chapter describes subsystem components and explains how
they are used within a system definition file (.msd).
What is a Subsystem Component?
A subsystem component is an Integration Flow Designer (IFD) 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 IFD.
The IFD 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 IFD displays a subsystem component graphically in the system window, as
shown in the following diagram.
Subsystem components have four basic characteristics: name, execution settings
(including sources and targets), and optional document links.
