You should consider the following before you set up your CICS® system
to act as your Web User Interface server:
- The CICS system that you select to act as your Web
User Interface server must be a dedicated CICS Transaction
Server for z/OS®, Version 3 Release 1 CICSPlex SM MAS connected to a CICS Transaction
Server for z/OS, Version 3 Release 1 CMAS. For information about how
to set up a MAS, see the CICS Transaction Server for z/OS Installation Guide.
- Decide how many Web User Interface servers you need. For example:
To set up your CICS system you should:
- 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.
- 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.
- 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:
- Ensure the CICSplex to which the Web User Interface server local
MAS belongs is only managed by the CMAS or CMASs that the Web User
Interface should connect to, or
- Ensure that the Web User Interface server connects to a specific
CMAS by specifying the CMASSYSID EYUPARM for the server local MAS.
- 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).
- 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.
