IMS for the COBOL Programmer: Data base processing with IMS


Book Description

IMS database processing hasn't changed much since this book was published in 1986. So if you have to maintain an old program that uses DL/I, you won't find a better book than this one. In it, you'll learn: the DL/I database structure; COBOL for using DL/I; how to work with secondary indexing, logical databases, and databases with logical relationships; how to use recovery and restart features; and the basic considerations for coding DL/I programs with CICS or IMS DC.




IMS for the COBOL Programmer: Data communications and message format service


Book Description

The second part of IMS for the COBOL Programmer is for MVS programmers only. It teaches you how to handle online programs that access IMS databases and run under the data communications (DC) component of IMS. This book also covers Message Format Service (MFS). MFS acts as an interface between the format of messages at a terminal and the I/O formats in your programs. So you'll learn how to use MFS to create formatted screens that are easy for operators to use. And you'll learn what tasks you can handle through MFS instead of having to code for them in your DC programs.




IBM IMS Solutions for Automating Database Management


Book Description

Over the last few years, IBM® IMSTM and IMS tools have been modernizing the interfaces to IMS and the IMS tools to bring them more in line with the current interface designs. As the mainframe software products are becoming more integrated with the Windows and mobile environments, a common approach to interfaces is becoming more relevant. The traditional 3270 interface with ISPF as the main interface is no longer the only way to do some of these processes. There is also a need to provide more of a common looking interface so the tools do not have a product-specific interface. This allows more cross product integration. Eclipse and web-based interfaces being used in a development environment, tooling using those environments provides productivity improvements in that the interfaces are common and familiar. IMS and IMS tools developers are making use of those environments to provide tooling that will perform some of the standard DBA functions. This book will take some selected processes and show how this new tooling can be used. This will provide some productivity improvements and also provide a more familiar environment for new generations DBAs. Some of the functions normally done by DBA or console operators can now be done in this eclipse-based environment by the application developers. This means that the need to request these services from others can be eliminated. This IBM Redbooks® publication examines specific IMS DBA processes and highlights the new IMS and IMS tools features, which show an alternative way to accomplish those processes. Each chapter highlights a different area of the DBA processes like: PSB creation Starting/stopping a database in an IMS system Recovering a database Cloning a set of databases

CICS for the COBOL Programmer


Book Description

This book takes up where Part 1 leaves off. Part 1 covers the basics of CICS...the elements you'll use in just about every CICS program you write. Part 2 covers the advanced features you'll use regularly, though you won't need all of them for every program. To be specific, this book teaches you: -- how to use browse commands to process a file sequentially -- how to use the browse commands to process VSAM alternate index files -- how DB2 database processing affects CICS programming (if you don't have any DB2 experience, this is just an introduction; you can get the additional DB2 training you'll need from our DB2 books, described on pages 3 and 4) -- how DL/I database processing affects CICS programming (again, this is an introduction; you can get the additional DL/I training you'll need from our IMS books, described on page 9) -- how to produce multi-page output using BMS page building -- how to use the ROUTE command to direct output to one or more terminals -- how to use terminal control commands that let you communicate directly with a terminal, bypassing BMS -- how to use temporary storage queues to store and retrieve small amounts of temporary data -- how to use transient data queues (transient data exists only from the time it's written to the time it's read) -- how to use interval control commands to start a task -- how to create an abend exit to keep your task from abending when an error occurs -- how to use the distributed processing features of CICS, including Distributed Program Link and APPC After finishing this book, then, you'll know a wide variety of advanced CICS features. Just as important, though, you'll know what features dosimilar things and when to use each one. And it's that knowledge that will save you time and work every day.

VSAM for the COBOL Programmer


Book Description

This book teaches you all you need to know to handle VSAM files in your COBOL programs. To make learning easier, this book contains dozens of examples of COBOL programs, JCL listings, and AMS job listings. So you'll see how the various language elements interrelate. And you'll have plenty of practical models to use when you're working with VSAM on your own.

An Introduction to IMS


Book Description

Normal 0 false false false MicrosoftInternetExplorer4 IBM's Definitive One-Stop Guide to IMS Versions 12, 11, and 10: for Every IMS DBA, Developer, and System Programmer Over 90% of the top Fortune(R) 1000 companies rely on IBM's Information Management System (IMS) for their most critical IBM System z(R) data management needs: 50,000,000,000+ transactions run through IMS databases every day. What's more, IBM continues to upgrade IMS: Versions 12, 11, and 10 meet today's business challenges more flexibly and at a lower cost than ever before. In An Introduction to IMS, Second Edition, leading IBM experts present the definitive technical introduction to these versions of IMS. More than a complete tutorial, this book provides up-to-date examples, cases, problems, solutions, and a complete glossary of IMS terminology. Prerequisite reading for the current IBM IMS Mastery Certification Program, it reflects major recent enhancements such as dynamic information generation; new access, interoperability and development tools; improved SOA support; and much more.
