Removing a region from a target region scope
CICS® system group CSGTGTS1 contains four target regions (CICSPA01, CICSPA02, CICSPA03, and CICSPA04) in CICSplex PLXPROD1. Work requests are routed 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.
- Remove target region CICSPA04 from CICS system group CSGTGTS1:
- From the Web User Interface main menu click Administration > Topology
administration > System groups to open
the System group definitions tabular view.
If the current context is not PLXPROD1, specify PLXPROD1 in the Context field and click Refresh.
- Click CSGTGTS1 in the System group name field to open a detail view and click the CICS systems in this CICS system group link. This opens the CICS system to CICS system group links tabular view.
- Click the Record check box beside the entry for CICSPA04 and click the Remove... button. This opens the Remove confirmation view.
- Click Yes to confirm the update.
- From the Web User Interface main menu click Administration > Topology
administration > System groups to open
the System group definitions tabular view.
- To check that CICSPA04 has been removed, from the main menu click Active workloads (WLM) > Active workload target distribution factors. This opens the Active workload target distribution factors view showing all target regions to which the workload can be routed. CICSPA04 should not appear in the list.
