IBM CICS Transaction Gateway Connector Release Notes - Mule 3

Support Category: Premium

Anypoint Connector for IBM CICS Transaction Gateway (IBM CTG Connector) provides integration with backend CICS applications using the CICS Transaction Gateway. For Java platforms, CTG implements the JCA resource adapter to connect Java applications to the CICS system. The connector connects Mule apps and CTG.

Guide: IBM CTG Connector Guide

Important:

  • The remote CICS Transaction Gateway must be at the same release level or later than the version of the JCA resource adapter.

  • The JCA resource adapter must match the CICS TG platform. For example, if you have CICS TG for Multiplatforms, you cannot connect with, to, or from a CICS TG that uses the z/OS resource adapter.

You must obtain the following JAR files to configure this connector:

  • ccf2.jar (CICS Common Connector Framework)

  • cicsjee.jar (CICS JEE)

  • ctgclient.jar (CTG Client Library)

  • ctgserver.jar (CTG Server Library)

  • geronimo-j2ee-connector_1.6_spec-1.0.jar (JCA 1.6 specification)

    The required JCA 1.6 library overcomes conflicts with JCA 1.5 which is shipped with Mule.

Features

  • Authentication - The connector uses under the hood, the IPIC (IP interconnectivity) protocol to establish communication with CICS regions over TCP/IP. This type of client also supports SSL authentication.

  • Execution of CICS Programs - The connector allows users to invoke CICS programs:

    • Using Channels and Containers.

    • Using a COMMAREA. Data transfers are limited to 32 KB.

  • Transactions - The connector leverages XA transactions by means of Mule’s transactional scope and the Bitronix Transaction Manager components.

  • DataSense - The connector supports adding metadata using through the Custom Metadata Tab option. Using the Copybook feature, a user can import a schema that describes the data structure going in and out of CTG so as to be used by a DataWeave component.

Fixed Issues

None
