Abstract
With the emergence of service-oriented architecture (SOA), the options for accessing existing CICS assets have become more varied than ever. This IBM Redbook is intended for IT architects who select, plan, and design SOA solutions that make use of CICS assets.
First, we provide an introduction to SOA and the options for transforming CICS assets into SOA solutions. Then we introduce the different architectures and technologies on which a CICS SOA solution can be based.
Next we offer a broad overview of the different technologies available for SOA enablement of CICS applications. We also offer a comparison of some of the current strategic technologies that include the CICS Web services support in CICS TS 3.1, CICS Transaction Gateway, CICS Web support, Link3270 bridge, and the CICS Service Flow Feature.
We continue with an in-depth analysis of the issues pertaining to security, transaction management, performance, application development, and data conversion when designing and developing your SOA solutions.
Finally, we document different customer scenarios, where these technologies have been successfully used to integrate existing enterprise information systems into new SOA solutions.
