Preparing a CICS system to act as the Web User Interface server

You should consider the following before you set up your CICS® system to act as your Web User Interface server:

To set up your CICS system you should:

  1. Create the CICS system and confirm that it is operational using the CICS-supplied installation verification procedures (IVPs). For information about the CICS IVPs, see the CICS Transaction Server for z/OS Installation Guide.
  2. Configure CICSplexes for your Web User Interface servers. We suggest that you configure a separate CICSplex for your Web User Interface servers. For information, see the CICS Transaction Server for z/OS Installation Guide.
  3. Ensure that the CMAS to which the Web User Interface connects is managing all CICSplexes that the Web User Interface server needs access to. This is because the Web User Interface server acts as an CICSPlex® SM API application. However, it is not necessary for the CMAS, to which the Web User Interface connects, to be managing any of the MASs in these CICSplexes. For information, see the CICS Transaction Server for z/OS Installation Guide.

    If there is more than one CMAS on the MVS image, that the Web User Interface server will run on, you need to consider which CMAS the Web User Interface should connect to depending on which CICSplexes the CMAS is managing. To control this connection you can either:

  4. Define the Web User Interface server CICS system to CICSPlex SM as a local MAS (for information, see the CICS Transaction Server for z/OS Installation Guide) and ensure that the CICS system has been set up correctly using the CICSPlex SM installation verification procedures (IVPs).
  5. Consider basic monitoring of your Web User Interface servers. You can use standard CICSPlex SM monitoring because the Web User Interface server is defined as a MAS.
