Implementing sysplex optimized dynamic workload routing

CICSPlex® SM provides dynamic workload management for CICS®. Sysplex optimized workload routing is enabled at the z/OS® coupling facility (CF) level by a region status (RS) server. So to optimize workload routing in a sysplex, you must configure and monitor an RS server, as part of a coupling facility data table.

For further details, see Setting up and running a region status server.

You define and modify CICSplexes using the EYUSTARTCPLEXDEF view set. In the CPLEXDEF detail view, you can view and modify a set of CF tuning parameters for the RS server, which provide sysplex optimized workload routing. However, it is recommended to use the default set of values.

When you upgrade from a previous release of CICS TS, existing workload definitions can span all currently supported CICS versions, without additional customization.
