CA5F: IBM CICS TG 'gateway' intercept plug-in support

Downloadable files


Abstract

SupportPac CA5F allows integration test tools to intercept ECI calls to CICS Transaction Gateway (CICS TG) from Java applications before they are processed by CICS TG.

Download Description

This SupportPac, CA5F, allows integration test tools to intercept External Call Interface (ECI) calls to IBM CICS Transaction Gateway (CICS TG), originating from Java Standard Edition (Java SE) and Java Enterprise Edition (JEE) applications. This, therefore, allows such applications to be tested without requiring a running CICS TG or CICS Transaction Server.

This SupportPac provides updated versions of the CICS TG V8.0 Java base classes and non-extended architecture (non-XA) ECI resource adapter. These updated files support the use of a Gateway intercept plug-in that can intercept application calls made through the Java Application Programming Interfaces (APIs). Documentation for the APIs is also provided by this SupportPac.

When enabled, a Gateway intercept plug-in is notified before a connection to a Gateway daemon is opened or closed, and before a request is sent to the Gateway daemon. Before a connection is opened, the plug-in can change properties of the connection object, and can prevent the connection from opening. Before a request is sent over a connection, the plug-in can change properties of the request object, and can cause the request to be returned to the application without being sent. Before a connection is closed, the plug-in can prevent the connection from closing. This allows a variety of scenarios to be simulated for application testing.

Possible uses:
Allows CICS interactions to be simulated for the purposes of application testing, without requiring a running CICS server or CICS Transaction Gateway.

Skill level required:
Plug-in developers must be familiar with developing applications in Java.

What's new in this release (V1.1)?

  • ctgclient.jar can now be used with Java request monitoring exits enabled.

Current Version: 1.1

Prerequisites

IBM CICS Transaction Gateway for z/OS V8.0, or later.
IBM CICS Transaction Gateway for Multiplatforms V8.0, or later.

For Java SE applications, Java 1.5 or later is required.

For JEE applications, a J2EE 1.4 certified application server or a JEE 5 certified application server that successfully runs the JCA resource adapter Install Verification Test (IVT), provided with CICS TG, is required.

Usage is restricted to remote mode topologies for JEE or Java applications. Java applications using the Java base classes must ensure that the only CICS TG jar file on their classpath is the version of ctgclient.jar provided by this SupportPac.
