Step 4 – Create CICS IPIC Connection

Configuring a CICS IPIC Connection is discussed in great detail in IBM’s z/OS Connect literature. To complete those configuration instructions, the following configurations need to be set.

A CICS system administrator must make the following configuration changes.

  1. Set the System Initialization (SIT) parameter TCPIP=YES.
  2. Define the TCP/IP address and host name for the z/OS Connect server.
  3. Add a TCP/IP listener to CICS. The following list shows the key attributes:
    1. POrtnumber

    2. PRotocol

    3. TRansaction

    4. Backlog

    5. HOST

    6. SOcketclose

    7. SSL

    8. CErtificate
  4. Use the following command to install the TCPIPSERVICE definition: CEDA DEF TCPIPSERVICE(service-name) GROUP(group-name)
  5. Choose whether to predefine or auto-install IPIC connections in CICS Transaction Server.
  6. Create a predefined or auto-installed IPCONN definition.

The details of this CICS connection should be given in the server.xml file for your z/OS connect server, so that z/OS connect server can communicate with CICS region.

Note:
The default port used for this connection is 1091.
