This IBM Redbook looks at IBM TXSeries for Multiplatforms, which is a premier IBM distributed transaction processing software for business-critical applications. Before discussing distributed transaction processing in general, we introduce the TXSeries for Multiplatforms Version 6.0 (V6.0). This book discusses distributed IBM Customer Information Control System (CICS) solutions and how best to develop distributed CICS applications. It also demonstrates enterprise integration with products such as relational database management system (RDBMS), IBM WebSphere MQ, and IBM WebSphere Application Server. In addition, it discusses system customization, reviewing features such as capacity planning, backup and recovery, and high availability. We discuss troubleshooting in TXSeries. We also provide details about migration from version to version for TXSeries and a migration checklist is included. We demonstrate a sample application that we created called BigBlueBank, its installation, and the server and client side programs. Other topics in this book include application development and system administration considerations.

Web-to host integration has become a well-known term and is understood as an integral part of any e-business. A majority of business-critical data and applications reside on IBM host systems such as IBM S/390, IBM AS/400 and IBM RS/6000. Making this information available to new users and using it in new ways across intranets, extranets and the Internet enable companies to reduce costs, improve services, generate new sources of revenue and establish a competitive advantage. The term legacy application extension is used to describe the trend where companies quickly move existing host applications to the intranet, extranet and the Internet without modifying existing applications. IBM Host Integration products provide a complete solution to address the legacy application extension space with solutions to address the needs of all user groups. This book provides a high-level technical overview of IBM Host Integration solutions. It addresses the issues of choosing a solution. The book features WebSphere network products that can be used to integrate the Web with existing customer host systems, including Host On-Demand, Host Publisher, and Screen Customizer. The functions they provide are compared to other Web-to-host products and features such as CICS Transaction Gateway, IMS Connect, etc.

This redbook details the configuration of a client/server environment consisting of IBM VisualAge COBOL, DB2 Universal Database, and TXSeries products on Windows NT. Installation and customization details as well as some application development techniques are covered. The book was written for those interested in the interaction of the above family of products when the applications are written in COBOL. Technical marketing, application development, and local area networking personnel will find this information particularly useful. The book guides the reader, step by step, in creating a working client/server environment, for both application development as well as application execution. This environment can be used for demonstration or as a reference when setting up a similar environment for productive use. Several practical examples are used throughout the book. Because the main focus of the book is on the environment and the interaction of the products, the program samples are kept as simple as possible. First, we provide the setup of an environment that only includes remote data access. Once the sample program is running, you know that your DB2 Universal Database (UDB) is installed and configured correctly. You can then go on to the next step, in which we add TXSeries to this scenario. We explain the environment by means of a CICS server program that accesses a DB2 database. This server program is called by a 3270 CICS client program as well as an external call interface (ECI) client program with a graphi

This redbook is primarily intended for application developers, system architects, and IT managers to understand the principals about transaction application development using the Encina Software from IBM/Transarc. The redbook consists of four parts. Part 1 gives a short introduction to Transaction Processing and how to position the different Encina modules. Part 2 discusses the specifics of the different Encina APIs, explains how to use them and discusses some specific application design considerations. Part 3 illustrates through a case study, how to design and develop a solution utilizing the Encina APIs. After an analysis and architecture description, we show how to design an Encina based solution, and how to develop the necessary code. The software developed through this phase is partly available on http://www.redbooks.ibm.com Part 4 finally discusses the important issues about configuration, administration, and maintenance of Encina infrastructure. In addition it also covers the deployment tasks of Encina based applications and shows some useful tools. In the case study we describe in part 3 we study a fictional customer who wants to enter the e-commerce market for direct sale. This gives him a market advantage against his competitors because of faster delivery process handling, higher degree of backoffice automation and better customer service through individualized marketing. While you read this case study, you may detect some needs already discussed in so many meetings....

This document is unique in its detailed coverage of NetFinity and its interactions with its agents on the OS/2, DOS/Windows and NetWare platforms. In addition, it shows how to exchange information with NetView for AIX and NetView for MVS. It provides information about LAN systems management. It focuses on how to manage and monitor different systems management components and take corrective action when it is needed. This document was written for technical professionals who have some knowledge of LAN systems management but have not used NetFinity to assist them with it. Some knowledge of systems management is assumed.
