Prerequisites

You must satisfy these system requirements.

Here are the system requirements for CICS® TS for IBM® z/OS®:
  • The server must be CICS V3.2 or later because IPIC is not available in earlier releases of CICS.
  • TCP/IP services must be active in the CICS server.
    • To activate these services, set the TCP system initialization parameter to YES.
    • To check the status of these services, issue a CEMT INQ TCPIP command and check that the status is open.
  • The CICS server must have access to a TCP/IP stack running on the same LPAR.
  • The TCP/IP network must extend between LPARs if CICS TG for IBM z/OS and the CICS server exist on different LPARs.
  • You must set the SEC system initialization parameter to YES to enable security.
  • You must have valid IBM RACF® user IDs and passwords.
Here are the system requirements for CICS TG:
  • CICS TG must be installed.
To test that the scenario works successfully you can use either the supplied samples, or your own applications. If you use the supplied samples, this scenario requires the following:
  • The sample CICS TG server program EC01 must be compiled, defined, and installed on CICS.
  • The CICS TG supplied Java™ sample EciB2 available on the client machine.

Testing your TCP/IP network

At the transport layer, issue ping requests between the operating system that is hosting your CICS TG and the LPAR where your CICS server resides. The ping request response, as shown in the example, confirms that the TCP/IP communications are working. The ping request also works if CICS TG and the CICS server are not in the same LPAR or if you are using multiple IP stacks on the same LPAR.
