Adding a routing region to an active workload

Assume that you are still routing 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 (using the CICS system definitions views), is running, and is linked to the target regions CICSPA01, CICSPA02, and CICSPA03.

1. Update the CICSPlex® SM definition for CICS system CICSPT02:
   • From the Web User Interface main menu click Administration > Topology administration > System definitions to open the CICS system definitions tabular view.

     If the current context is not PLXPROD1, specify PLXPROD1 in the Context field and click Refresh.

   • Select the record for CICSPT02 and click the Update... button.
   • Change the AOR dynamic routing mode field to YES.
   • Click Yes to confirm the update. This change takes effect when routing region CICSPT02 is next started.
2. Associate CICSPT02 with workload specification WLSPAY01:
   • From the main menu, click Administration > Workload manager administration > Specifications.
   • On the WLM specifications view, click the Record check box beside the entry for WLSPAY01 and click Associate CICS system....
   • 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:

• Open the WLM specification tabular view and click the entry for WLSPAY01. This opens a detail view.
• Click the CICS systems associated with this workload specification link. Both CICSPT01 and CICSPT02 should be listed in the WLM specifications to CICS system links tabular view.
