Governance concerns the methods that businesses use to control important aspects of their business and these methods must be measured. Compliance is the tolerance to the criteria that have been set. CICS v4 allows you to configure your system to produce application compliance data feeds and events without application change to show solution compliance on a dashboard. The governance theme will largely be linked to CICS TS v4.1 which allows you to generate business events without requiring application change. This new capability will allow you to populate business dashboards provided by WebSphere® Business Monitor and to search for patterns in events with WebSphere Business Events. For business event processing, when CICS TS is operating as a stand-alone system, or used in conjunction with WebSphere Business Monitor or WebSphere Business Events (or both), it will enable you to understand and manage your business more easily, and to monitor risk and business compliance more effectively.

The CICS Transaction Gateway (CICS TG) is widely used to provide access to CICS COMMAREA-based programs and 3270 transactions from Java environments. This IBM Redbook shows you how to build a robust CICS TG configuration for a variety of different configurations. First we introduce the facilities of the CICS TG, followed by step-by-step explanations of how to use the different protocols (TCP/IP, TCP62, APPC and EXCI) used for communication with a CICS TS V2.2 region on z/OS, and how to secure your CICS region when receiving External Call Interface (ECI) or External Presentation Interface (EPI) requests. Next, we provide details on how to configure the CICS TG V5 on either z/OS or Linux to connect a Java client application to a CICS region. The use of the Secure Sockets Layer (SSL) protocol to encrypt the communication from the Java application to the CICS TG is included in these scenarios. Finally, we offer two scenarios to illustrate how to configure WebSphere Application Server V4 on the Windows or z/OS platforms, to use the supplied ECI resource adapter to allow J2EE applications to make ECI calls to CICS.

The Web services support in CICS® Transaction Server Version 3 enables your CICS programs to be Web service providers or requesters. CICS supports a number of specifications including SOAP Version 1.1 and Version 1.2, and Web services distributed transactions (WS-Atomic Transaction). This IBM® Redbooks® publication reviews CICS Web Services performance in two particular areas: MTOM/XOP: Here we focus on performance benefits that can be achieved by taking advantage of the MTOM/XOP standard to transmit large binary data objects. The single inquiry function of the CICS catalog manager application has been modified to return an image of the requested item in addition to its details. This function is exposed through a Web service. Security: There are a number of ways to secure your CICS Web Services messages. Here we look at two technologies: WS-Security and DataPower®. We compare the performance and relative merits of using WS-Security with and without DataPower, and discuss what factors might influence your choice of technology. We highlight tools that can help you to understand the performance profile of Web service interactions with CICS, such as; - RMF z/OS® Resource Measurement Facility (RMF) - IBM CICS Performance Analyzer for z/OS (CICSPA) - ITCAM for SOA - OMEGAMON® XE for CICS on z/OS This book considers performance by using different scenarios including Security, MTOM/XOP, and the use of the IBM Tivoli® Monitoring tools to help identify problems that can affect the performance of Web Services.

We wrote this IBM® Redbooks publication for clients who implement the Java™ language support that is provided by CICS® Transaction Server for z/OS® V3.2. Our prime audience is CICS and z/OS system programmers who provide support for Java application development and Java application programmers who need a gentle introduction to Java development for CICS. In this book, we assume that you have knowledge of z/OS, CICS, UNIX® System Services, and Java. We start by reviewing the basic concepts of the z/OS, CICS TS V3.2, and Java environments, and introduce new terminology. We then discuss the software and hardware requirements for developing and executing Java applications in CICS TS V3.2. Next we show you how to customize the application development environment, UNIX System Services, MVS™, and CICS. Additionally, we briefly discuss three possible application development roadmaps: Java application programs that use CICS services, IIOP server applications, and CICS Enterprise Beans. Subsequent chapters contain an expanded explanation and examples of Java application programs that use CICS services and how to use CICS-supplied Java class library and the Java Virtual Machine (JVM™). We then present a CICS business application that has presentation and business logic. Finally, we provide guidance on debugging and problem determination.

Securing access to information is important to any business, especially for business-critical systems that manage sensitive data, as is often the case for systems based on IBM® Customer Information Control System (CICS®). Security becomes even more critical for implementations structured according to service-oriented architecture (SOA) principles, due to loose coupling of services and applications, and their possible operations across trust boundaries. In this IBM Redbooks® publication, we consider the different ways that CICS Web services can be secured. We consider transport-level security mechanisms such as SSL/TLS and CICS support for the message-based security specifications WS-Security and WS-Trust. To assist solution and security architects, we outline the main planning considerations and make recommendations on the choice of a security solution. For the systems programmer, we provide detailed setup guidance for configuring common security scenarios. These scenarios include interoperability with WebSphere DataPower and using Tivoli Federated Identity Manager (TFIM) as a Security Token Service. For each scenario, we provide step-by-step configuration information for CICS and the other involved systems, including WebSphere Application Server, WebSphere DataPower, and TFIM.

Today more and more companies are embracing the principles of on demand business by integrating business processes end-to-end across the company and with key partners, enabling them to respond flexibly and rapidly to new circumstances. The move to an on demand business environment requires technical transformation, moving the focus from discrete applications to connected, interdependent information technology components. Open standards such as Web services enable these components to be hosted in the environments most appropriate to their requirements, while still being able to interact easily, independent of hardware, run-time environment, and programming language. The Web services support in CICS® Transaction Server Version 3 enables your CICS programs to be Web service providers and requesters. CICS supports a number of specifications including SOAP Version 1.1 and Version 1.2, and Web services distributed transactions (WS-Atomic Transaction). This IBM® Redbooks publication describes how to configure CICS Web services support for HTTP-based and WebSphere® MQ-based solutions, and demonstrates how Web services can be used to integrate J2EE™ applications running in WebSphere Application Server with COBOL programs running in CICS. The book begins with an overview of Web services standards and the Web services support provided by CICS TS V3. Complete details for configuring CICS Web services using both HTTP and WebSphere MQ are provided next. We concentrate on the implementation specifics such as security

A key feature of CICS TS V3 is its ability to use CICS to provide an execution environment for Web services applications. This IBM Redbooks publication contains the specific management requirements of such applications and shows how CICSPlex SM can be used to manage these applications in an easy to use fashion. We present an overview of Web services, discuss how CICS implements Web services, discuss the Web services support of CICS TS V3.1 and the enhancements provided with CICS TS V3.2, and give a small overview of CICSPlex SM and how the CICSPlex SM WUI can assist with both CICS Web Services installation and management. We also discuss the different techniques that can be used to provide high system availability and workload management for CICS Web service applications and how high availability is provided across a Parallel Sysplex. We then describe how CICSPlex SM is used to define and manage the required CICS definitions to run the Web services application and configure CICS as a service provider, show how to set up a CICS Web services requester application for high availability, and describe a practical example of a CICS Web services implementation based on a proof of concept for a large financial group.
