Adding a routing region to an active workload

Start of change

This example describes how to use the Web User Interface (WUI) to add a routing region to an active workload, without disrupting that workload. Assume that you are still balancing the workload in CICSplex PLXPROD1, via workload specification WLSPAY01, and that work requests are being routed by CICSPT01 among the target regions in CICS system group CSGTGTS1. Now you want to add a second routing region--CICSPT02--to the workload. Region CICSPT02 has been defined to CICSplex PLXPROD1 (via the CICSSYS panels) and is running.

  1. Update the CICSPlex® SM definition for CICS system CICSPT02.
    1. From the Web User Interface main menu click Administration views-->Topology administration views-->CICS system definitions to open the CICS system definition tabular view.
    2. If the current context is not PLXPROD1, specify PLXPROD1 in the Context field and click .
    3. Select the record for CICSPT02 and click Update. Click Yes on the confirmation panel to confirm the update.
    4. Scroll down to the Start of changeWorkload manager statusEnd of change field and select YES from the drop-down menu.
    5. Click Yes at the bottom of the screen to confirm the update. This change takes effect when routing region CICSPT02 is next started.
  2. Associate CICSPT02 with workload specification WLSPAY01.
    1. From the main menu click Administration views-->Workload manager administration views-->Workload specifications .
    2. Select the entry for WLSPAY01 and click Associate CICS system.
    3. In the CICS system field, type in CICSPT02 and click Yes to confirm the update.

When CICSPT02 has been restarted, you can verify that it has been added to WLSPAY01 as follows:

  1. Open the Workload management (WLM) specification tabular view and click on the entry for WLSPAY01. This opens a detail view.
  2. Click CICS systems associated with this workload specification. Both CICSPT01 and CICSPT02 should be listed.

To check that CICSPT02 is part of the active workload, from the main menu, click Active workload views-->Routing regions in an active workload This opens a tabular view showing entries for both CICSPT01 and CICSPT02.
