Planning CICS system definitions

To manage a CICS® region with CICSPlex® SM, you must associate the CICS region with a CICSplex that is defined to CICSPlex SM. The definition that establishes this association also contains information about how the CICS system is to use the BAS, WLM, RTA, and monitoring components of CICSPlex SM.

1. Gather the basic information about your CICS region to create a definition.
   1. Decide the name by which this CICS region is to be known to CICSPlex SM.
      This name can be up to 8 characters in length.
   2. Find the APPLID, that is, the z/OS® Communications Server application identifier of the CICS region.
   3. Find the SYSID, that is, the CICS system identifier of the CICS region.
   This information is sufficient to add the definition to the data repository. If you have special BAS, WLM, RTA, or monitoring requirements for any CICS region, you can gather the information before adding the definition or update the definition later.
2. Optional: Gather additional information about your CICS region for the definition.
   1. If you are implementing system availability monitoring (SAM), find the name of the primary CMAS and the hours of operation of the CICS region.
      The primary CMAS is the CMAS that the CICS region usually connects to.
   2. Decide whether or not to simulate CICS command checking.
   3. Decide whether or not to simulate CICS resource checking.
   4. Decide what types of connections are required to other CICS regions and how many sessions to allow on each connection.
      If you want to create IP interconnectivity (IPIC) connections, you must also the port number, the host name, and network ID of the CICS region.
   5. Decide what time zone of the CICS region is to use, if it is not to be the same as that of its CMAS.
