Prerequisites

You must ensure that the prerequisites for CICS® Transaction Server, CICS Transaction Gateway, and WebSphere® Application Server are satisfied.

Here are the system prerequisites for CICS Transaction Server for z/OS®:

  • The CICS server must be CICS Transaction Server for z/OS Version 4.1 or later, with the APAR fixes described in Configurations that support identity propagation.
  • The z/OS identity propagation function must be that provided by z/OS, Version 1.11 or later.
  • 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.
  • The TCP/IP network must extend between LPARs if CICS Transaction Gateway for 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 RACF® user IDs and passwords.

Here are the system prerequisites for CICS Transaction Gateway:

  • CICS Transaction Gateway must be installed on the same sysplex as CICS Transaction Server. For more information see Sysplex restrictions.
  • The CICS Transaction Gateway STDENV file must be correctly configured. For more information see STDENV file.

Here are the system prerequisites for WebSphere Application Server:

  • Administrative security must be enabled in WebSphere Application Server.
  • WebSphere Application Server must already be configured to use an LDAP server and LDAP authentication, and a Distinguished Name (DN) must exist.
  • The CICS Transaction Gateway ECI resource adapter must be installed on WebSphere Application Server. For more information, see Deploying the ECI resource adapter on WebSphere Application Server for z/OS.
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 ECIDateTime sample EJB application supplied with CICS Transaction Gateway. This sample must be installed onto WebSphere Application Server.
  • The sample CICS Transaction Gateway server program EC01 must be compiled, defined, and installed on CICS.
