Organizing CICS systems into groups

CICS® system groups are a basic building block of the CICSPlex® SM configuration. You are recommended to create some standard groups, such as all AORs in a CICSplex and all CICS systems in a CICSplex, when you first configure your CICSPlex SM environment. In this example, you will create a CICS system group, CSGAORS1, in CICSplex PLXPROD1, and add CICS systems CICSPA01, CICSPA02, and CICSPA03 to that group.

    Start of change
  1. Display any CICS system groups already defined in the CICSplex PLXPROD1.
    1. From the main menu click CICSPlex SM operations views --> System group definitions to open the System group definition tabular view.
    2. If the context is not PLXPROD1, specify PLXPROD1 in the Context field and click Refresh. The context is then fixed for all subsequent views and menus until changed.
  2. Create a new CICS system group.
    1. Click Create to open the System group definition create view.
    2. Provide the following information:
      System group name
      CSGAORS1
      Description
      AORs PA01, PA02, PA03
    3. Click Yes. The System group definition tabular view is redisplayed showing an entry for the new group.
  3. Add CICS systems to the new CICS system group.
    1. From the CICSPlex SM operations views menu open the CICS system definition tabular view.
    2. Select the entry for CICSPA0 and click Add to CICS system group.
    3. In the Group which member will join field type in CICSPA01 and click Yes. The CICS system CICSPA01 is added to the CSGAORS1 group and the CICS system definition tabular view is redisplayed .

    You have two more systems (CICSPA02 and CICSPA03) to add to the group, so need to repeat this step (step 3) twice more.

  4. If you want to check when you have finished that CICSGRP contains the correct systems, open the System group definition tabular view and double click on CICSGRP in the System group name field. The System group definition detailed view is displayed. Select CICS systems in this system group to open the Link between CICS system and CICS system group view.
  5. Update the CICS system group.

    Assume that you want to remove CICS system CICSPA02 from the group. Open the Link between CICS system and CICS system group view and select the entry for CICSPA02. Click Remove. The Remove confirmation panel is displayed. Click Yes to confirm the operation.

    The Link between CICS system and CICS system group view is redisplayed, showing CICS systems that are still defined as members of CSGAORS1. The list does not include CICSPA02.

  6. End of change
