iIS Process System Software
Chapter 2 Setting Up an iIS Process Management System 47
To set up an iIS process system, install the iIS system software modules that
support development on your development nodes. Then install the iIS runtime
modules on the nodes on which you will be executing your distributed enterprise
applications.
iIS Backbone
If you are integrating applications with the iIS Backbone, also install the iIS
runtime. For more information, refer to the iIS Installation Guide. For management
functions specific to the iIS Backbone, refer to the iIS Backbone System Guide.
iIS Process System Software
iIS process system software consists of a number of software modules that
provide—or are used to develop and manage—many of the iIS process system
components illustrated in Figure 2-1 on page 46. These modules, organized by
functional category, are described in the following table. The table also indicates
which system software modules are marked for use as compiled partitions.
