Using CICSPlex SM with BTS

Rather than writing your own distributed routing program, you can use CICSPlex® SM services to route BTS activities around your BTS-sets. For BTS support, you need the CICSPlex SM component of CICS® Transaction Server for OS/390®, Version 1 Release 3.

Overview of CICSPlex SM Workload Management

CICSPlex SM’s workload management (WLM) function provides a dynamic routing program that can route eligible transactions (those defined as dynamic) from a requesting region to a suitable target region selected at the time the transaction is initiated.

WLM functions

CICSPlex SM’s dynamic routing program supports:

Using CICSPlex SM to route BTS activities

When routing BTS activities around a BTS-set, CICSPlex SM Workload Management selects a target region based on:

The CICSPlex SM component of CICS Transaction Server for OS/390, Version 1 Release 3 understands BTS processes and activities. This makes it possible to separate a BTS workload based on process-type. For example, you could specify that WLM is to route all processes of process-type 'TRAVEL' to one region in the BTS-set, and all processes of type 'PAYROLL' to another region.

CICSPlex SM WLM and the Start of changeIBM CICS Interdependency Analyzer for z/OSEnd of change understand affinities between BTS activities and processes. Although BTS itself does not introduce any affinities, and discourages programming techniques that do, it does support legacy code, which may introduce affinities. You must define such affinities to CICSPlex SM WLM, so that it is able to make sensible routing decisions. It is particularly important to specify each affinity’s lifetime; failure to do so may restrict WLM’s routing options unnecessarily.
