Deployment

You can deploy Substation ES and IMS Interface in various ways to meet system, application, and workload requirements.

The following are the possible configurations:

• A Substation ES region can start and communicate with various unrelated host-side interfaces. For example, a CICS and IMS interface can be active within a single Substation ES region.
• The IMS control region and Substation ES can each execute in the same or an adjacent LPAR images as long as XCF communicates with both LPARs.
• Substation ES can communicate with many IMS interfaces and, therefore, with multiple IMS control regions.
• If multiple IMS interfaces are started for the same Substation ES instance, each IMS interface can communicate with the same or different IMS control regions.

The following figure shows how you can deploy IMS Interface:
