Objectives

Once complete you should be able to enable atomic transaction support for Web services in CICS as a requester or provider and understand the SOAP message flows that take place between coordinator and participant.

Using this new functionality and the existing transactional features that CICS supports, you can create fully coordinated cross-system atomic transactions that interact with a variety of recoverable resources.

Prerequisites

This tutorial is written for CICS programmers and administrators whose skills and experience include basic CICS resource management and Web services knowledge. You should have a basic familiarity with Unix System Services, XML, SOAP, CICS transactions CEDF, and CEMT.

System requirements

To run the examples in this tutorial, you need IBM CICS Transaction Server for Z/OS Version 3.1 or greater with two available CICS regions.
