This example describes how to use the Web User Interface (WUI) to increase the number of regions in an existing target scope without disrupting an existing workload. Assume that you have implemented workload balancing in CICSplex PLXPROD1, via workload specification WLSPAY01, and that work requests are being routed among target regions CICSPA01, CICSPA02, and CICSPA03. These target regions all belong to CICS system group CSGTGTS1. Now you want to add a fourth region--CICSPA04--to group CSGTGTS1. Region CICSPA04 has been defined to CICSplex PLXPROD1 and is running.
This change takes effect when the target region CICSPA04 is next started.
When the target region CICSPA04 has been started, you can check that the workload is active by clicking Active workload views-->Target regions in an active workload This opens the Target region in an active workload view showing all target regions (including CICSPA04) to which work requests in this workload can be routed.
