Viewing optimization status for a CICS region

You can view the optimization status of CICS® regions participating in workloads, in CICS Explorer® or in the CICSPlex® SM Web User Interface (WUI).

If you are using CICS Explorer, open the CICSplex Explorer view in the CICS SM perspective, and then expand the CICSplex tree and then the Workload Management section to see all the workloads. Expand the tree for an active workload to see router and target systems that are associated with the workload. For details, see Viewing workloads in a CICSplex in the CICS Explorer product documentation.

If you are using the CICSPlex SM WUI, use the Routing regions or Target regions views located in the Active workloads list view to view the optimization status for a CICS region.

The Optimization status attribute reports the status of the current target region for the sysplex optimized workload routing function.

These values are possible:
ACTIVE
This target region is running in sysplex optimized workload state.
INACTIVE
This region can run in sysplex optimized workload state; however, it is not currently sysplex optimized for one or more of the following reasons:
  • The region has no connection to an RS server.
  • The region is connected to an RS server; however, the server cannot connect to the z/OS® coupling facility.
  • The optimization enablement setting for the region is set to Disabled. The enablement setting for the region must be set to Enabled before any sysplex optimized routing functions can be activated.
    Note: You can reset the sysplex optimization enablement setting in the CICS system definition view to change the value in preparation for the next region startup. The enablement setting can also be changed in an active region using the MAS view, but will revert to the setting in the CICS system definition when the region is restarted.
  • The RS server update frequency value for this region is 0, which means that the optimization capabilities for this region when acting as a routing target are not enabled.
    Note: You can set the UPDATERS value to 0 for regions that are used as dynamic routers only. Setting this value to 0 prevents the region from making unnecessary region status broadcasts to the Region Status (RS) server.
N_A
The target region is not at a CICS release that supports region status recording. Only non-optimized WLM routing decisions can be made.
