Adding or removing systems in a CICS system group

You can add CICS® systems or other system groups to a CICS system group. Any systems that you add can be a router for only one group. If this system group is a router for a workload and you add a system that is already a router for a different workload, you get a conflict, which must be resolved before you can save the changes. If this system group is not a router for a workload, then the conflicts section shows the message The system group is not assigned to a workload so no conflicts can occur when the editor is opened.
Note: If the system group is part of a platform, you cannot edit the group members by using this editor. You must edit the CICS platform project for the platform instead.

Before you begin

You can open the System Group Definition editor from the System Group definitions view, a system group in the CICSplex Explorer view, or by clicking the Targets link in the Workload Specification editor.

Procedure

  1. Open the System Group Definition editor for the group that you want to change. Click Add. The Add member window opens and shows the systems and system groups in the CICSplex. Any systems or system groups that are already in the system group definition are shown as unavailable.
  2. Click the system or system groups that you want to add and click OK. You can use the Shift or Ctrl keys (shift or cmd keys for OS X) to select multiple resources. The selected system or system groups are added to the System Group Definition editor. If you add a system and there is a conflict, the conflicting system is decorated with an error symbol, and shown in the Conflicts section. You must resolve all conflicts before you can save your changes. If you want to undo the Add action, you can press Ctrl+Z (cmd+Z for OS X) at any time before you save the changes.
  3. In the Conflicts section, click the system that you want to resolve. Choose an action from the menu:
    • To redefine the system to be a router for this workload, click Redefine to be a router for this workload
    • To keep the system as a router for the existing workload, click Keep as a router for the existing workload.
  4. When all conflicts are resolved, press Ctrl+S (cmd+S for OS X) to save your changes.

Results

The changes are made to the system group definition, and shown in the editor.

You can remove systems or system groups from the system group definition by selecting the resource you want to remove and clicking Remove. Press Ctrl+S (cmd+S for OS X) to save your changes.
