Before you can complete this scenario, you must ensure that the system requirements for CICS® Transaction Server and CICS Transaction Gateway are satisfied.

CICS Transaction Server on IBM® z/OS®:
  • TCP/IP services must be active in the CICS server.
    • To activate these services, set the TCPIP 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.
CICS Transaction Gateway:
  • CICS Transaction Gateway must be correctly installed.
  • A working connection from CICS Transaction Gateway to CICS is required. This can be an IPIC, SNA, or TCP/IP connection. This scenario uses a TCP/IP connection to CICS. For more information see Configuring TCP/IP.
To test the scenario works successfully you can either use the supplied samples, or your own applications. If you choose to use the supplied samples, this scenario requires:
  • The sample CICS TG server program EC01 to be compiled, defined, and installed on CICS.
  • The CICS Transaction Gateway supplied Java™ sample EciB1 be available on the Java client machine.
