Book Description
This IBM® Redbooks® publication, intended for architects, application developers, and system programmers, describes how to design and implement Java web-based applications in an IBM CICS® Liberty JVM server. This book is based on IBM CICS Transaction Server V5.3 (CICS TS) using the embedded IBM WebSphere® Application Server Liberty V8.5.5 technology. Liberty is an asset to your organization, whether you intend to extend existing enterprise services hosted in CICS, or develop new web-based applications supporting new lines of business. Fundamentally, Liberty is a composable, dynamic profile of IBM WebSphere Application Server that enables you to provision Java EE technology on a feature-by-feature basis. Liberty can be provisioned with as little as the HTTP transport and a servlet web container, or with the entire Java EE 6 Web Profile feature set depending on your application requirements. This publication includes a Technology Essentials section for architects and application developers to help understand the underlying technology, an Up-and-Running section for system programmers implementing the Liberty JVM server for the first time, and a set of real-life application development scenarios.

Book Description
Mainframe computers play a central role in the daily operations of many of the world's largest corporations. Batch processing is still a fundamental, mission-critical component of the workloads that run on the mainframe. A large portion of the workload on IBM® z/OS® systems is processed in batch mode. This IBM Redbooks® publication is the first volume in a series of four in which we specifically address new technologies introduced by IBM to facilitate the use of hybrid batch applications that combine the best aspects of Java and procedural programming languages such as COBOL. This volume specifically focuses on the latest support in CICS to run batch tasks. The audience for this book includes IT architects and application developers, with a focus on batch processing on the z/OS platform in a CICS environment.

Book Description
This IBM® Redbooks® publication provides information about the new Java virtual machine (JVM) server technology in IBM CICS® Transaction Server for z/OS® V4.2. We begin by outlining the many advantages of its multi-threaded operation over the pooled JVM function of earlier releases. The Open Services Gateway initiative (OSGi) is described and we highlight the benefits OSGi brings to both development and deployment. Details are then provided about how to configure and use the new JVM server environment. Examples are included of the deployment process, which takes a Java application from the workstation Eclipse integrated development environment (IDE) with the IBM CICS Explorer® software development kit (SDK) plug-in, through the various stages up to execution in a stand-alone CICS region and an IBM CICSPlex® environment. The book continues with a comparison between traditional CICS programming, and CICS programming from Java. As a result, the main functional areas of the Java class library for CICS (JCICS) application programming interface (API) are extensively reviewed. Further chapters are provided to demonstrate interaction with structured data such as copybooks, and how to access relational databases by using Java Database Connectivity (JDBC) and Structured Query Language for Java (SQLJ). Finally, we devote a chapter to the migration of applications from the pooled JVM model to the new JVM server run time.

Book Description
This IBM® Redbooks® publication describes the new channels and containers support in IBM Customer Information Control System (CICS®) Transaction Server V5.2. The book begins with an overview of the techniques used to pass data between applications running in CICS. This book describes the constraints that these data techniques might be subject to, and how a channels and containers solution can provide solid advantages alongside these techniques. These capabilities enable CICS to fully comply with emerging technology requirements in terms of sizing and flexibility. The book then goes on to describe application design, and looks at implementing channels and containers from an application programmer point of view. It provides examples to show how to evolve channels and containers from communication areas (COMMAREAs). Next, the book explains the channels and containers application programming interface (API). It also describes how this API can be used in both traditional CICS applications and a Java CICS (JCICS) applications. The business transaction services (BTS) API is considered as a similar yet recoverable alternative to channels and containers. Some authorized program analysis reports (APARs) are introduced, which enable more flexible web services features by using channels and containers. The book also presents information from a systems management point of view, describing the systems management and configuration tasks and techniques that you must consider when implementing a channels and containers solution. The book chooses a sample application in the CICS catalog manager example, and describes how you can port an existing CICS application to use channels and containers rather than using COMMAREAs.

Book Description
The service-oriented architecture (SOA) style of integration involves breaking an application down into common, repeatable services that can be used by other applications (both internal and external) in an organization, independent of the computing platforms on which the business and its partners rely. In recent years CICS® has added a variety of support for SOA and now provides near seamless connectivity with other IT environments. This IBM® Redbooks® publication helps IT architects to select, plan, and design solutions that integrate CICS applications as service providers and requesters. First, we provide an introduction to CICS service enablement and introduce the architectural choices and technologies on which a CICS SOA solution can be based. We continue with an in-depth analysis of how to meet functional and non-functional requirements in the areas of application interface, security, transactional scope, high availability, and scalability. Finally, we document three integration scenarios to illustrate how these technologies have been used by customers to build robust CICS integration solutions.
