Removing a region from a target region scope

Start of change

CICS system group CSGTGTS1 contains four target regions (CICSPA01, CICSPA02, CICSPA03, and CICSPA04) in CICSplex PLXPROD1. Work requests are balanced among these target regions, and the routing is controlled by workload specification WLSPAY01.

This example describes how to use the Web User Interface (WUI) to remove region CICSPA04 from the group CSGTGTS1, without disrupting the active workload.

  1. Remove target region CICSPA04 from CICS system group CSGTGTS1.
    1. From the Web User Interface main menu click Administration views-->Topology administration views-->CICS system group definitions to open the CICS system group definition tabular view.
    2. If the current context is not PLXPROD1, specify PLXPROD1 in the Context field and click .
    3. Click on the entry for CSGTGTS1, to open a detail view and click CICS systems in this CICS system group. This opens the Link between CICS system and CICS system group view.
    4. Select the record for CICSPA04 and click Remove. This opens the Remove confirmation screen.
    5. Click Yes to confirm the update.
  2. To check that CICSPA04 has been removed, click Active workload views-->Target regions in an active workload. This opens the Target region in an active workload view showing all target regions to which the workload can be routed. CICSPA04 should not appear in the list.
