iIS Process System Software

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.
