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.
