IBM CICS TG (for Multiplatforms and for z/OS)

9.1 and 9.2

IBM CICS TG SDK

9.1 and 9.2

Features

  • Response Time is now configurable. This field is located under Additional Settings in the connector’s configuration. This timeout is the maximum amount of time in milliseconds that a managed connection attempts to wait for a response to a request. A value of 0 represents no timeout. The default is 30000 milliseconds (30 seconds).

Fixed Issues

  • The connector occasionally assumed incorrectly that the input payload was empty. This was fixed so that regardless of the type of InputStream the connector’s operations receive, the connector works correctly. (SE-12156)

9.1 and 9.2

IBM CICS TG SDK

9.1 and 9.2

Notes:

  • The remote CICS TG must be at the same or a higher release level 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 to it from a CICS TG with the z/OS resource adapter.

The following JAR files are required to set up a connector configuration:

  • 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)

JCA 1.6 is needed as a required library to overcome conflicts with JCA 1.5 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.

Known Issues

  • Although the inclusion of JCA 1.6 as a required library is meant to solve compatibility conflicts with the JCA 1.5 shipped with Mule, it is yet unknown if this causes side effects.
