Preparing to set up a MAS

This topic introduces the actions you need to undertake when you set up a MAS. Full details are given in CICS Transaction Server for z/OS® Installation Guide. You need to:

Define CICSPlex® SM’s resources to the CMAS
Start of changeThe CICSPlex SM code, for MASs , is a CICS® application, so you must define CICSPlex SM’s resources to the managed CICS system. Resource definitions, and instructions for their application, are supplied for all CICS environments (CICS Transaction Server).End of change
Define the CICS system to CICSPlex SM
Use the CICS system Definition WUI view or the CICSSYS EUI view.
Modify the MAS’s startup JCL
The startup JCL must refer to the appropriate CICSPlex SM data sets and include the required CICS system initialization parameters are included.
Ensure that the CMAS is started before the MAS
If the MAS is active before the CMAS, the MAS-attach process waits until the CMAS is started. This means that no CICSPlex SM function is available to the CICS system until the CMAS is available. (However, CICSPlex SM’s WLM functions are available in these circumstances if the workload has been activated.) Delays in the MAS-attach process do not affect the functions of the CICS system itself.
