Adding a CICS system to a CICS system group

You can assign a CICS system to one or more system groups to logically group similar regions together. You can also implement workload management using system groups, so assigning the systems to appropriate groups is important.

About this task

If you do not want to use workload management, you can organize CICS® systems into CICS system groups as required. For example, you might group all application-owning regions (AORs) together, all file-owning regions (FORs) together, and all terminal-owning regions (TORs) together.

If you do want to use workload management, you must ensure that each CICS system that acts as a target region for specific workload processing is in the same CICSplex as the CICS systems acting as routing regions. The routing regions associated with a CICSplex can be in the same or different MVS™ images. Also CICS systems acting as routing regions must be locally attached to a CMAS.

You can add CICS systems to a system group using CICS Explorer® or the Web User Interface.

Procedure

Using the CICS Explorer, open the SM perspective and click Window > Show View > System definitions to list the system definitions.
1. Right-click the system definition that you want to assign and click Add to Group.
2. Select the system group.
Using the Web User Interface, click Topology administration > System definitions.
1. Select a CICS system definition and click Add to CICS system group.
2. Specify the name of an existing system group and click Yes.

Results

The CICS system is added to the specified system group.

What to do next

After you have created a basic topology, you can add additional CMASs to create a highly available environment.
