The CICS Transaction Gateway (CICS TG) is used widely to provide access to CICS programs from Java environments. It provides the IBM implementation of the J2EE Connector Architecture (JCA).

This IBM Redbooks publication introduces the new facilities of the CICS TG for z/OS V6.0 and V6.1, which provide improvements in the areas of transactional integration, systems management, performance, security, and ease of use.

Included in this book are a set of configuration scenarios for a variety of different deployment topologies for integrating J2EE applications on WebSphere Application Server with CICS TS for z/OS. This book provides step-by-step explanations about how to configure connections between each tier of the test environment. We show you how to enable support for global transactions which span resources on different systems. We also cover the configuration of CICS TG security, including the use of JSSE for establishing secure SSL connections to the CICS TG.
