The author discusses direct access storage devices, the history of the development of VSAM, VSAM's purposes and benefits, the three different VSAM file types and their similarities to other access methods, how space is allocated, and how data is formatted. Chapters also cover how VSAM keeps track of data, the structure of an index record, the structure and function of the VSAM catalog, and the many commands available through Access Methods Services (AMS) to mold VSAM to your particular requirements. There is also practical advice on recovering from and preparing against disaster, security of data files and passwords, and accessing VSAM through COBOL, PL/1, and the Assembly Language.

Download or read book VSAM Demystified written by Mary Lovelace and published by IBM Redbooks. This book was released on 2022-08-24 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Virtual Storage Access Method (VSAM) is one of the access methods used to process data. Many of us have used VSAM and work with VSAM data sets daily, but exactly how it works and why we use it instead of another access method is a mystery. This book helps to demystify VSAM and gives you the information necessary to understand, evaluate, and use VSAM properly. This book also builds upon the subject of Record Level Sharing and DFSMStvs. It clarifies VSAM functions for application programmers who work with VSAM. The practical, straightforward approach should dispel much of the complexity associated with VSAM. Wherever possible an example is used to reinforce a description of a VSAM function. This IBM® Redbooks® publication is intended as a supplement to existing product manuals. It is intended to be used as an initial point of reference for VSAM functions.

Download or read book Introduction to the New Mainframe IBM z VSE Basics written by Mike Ebbers and published by IBM Redbooks. This book was released on 2016-03-02 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: This IBM® Redbooks® publication is based on the book Introduction to the New Mainframe: z/OS Basics, SG24-6366, which was produced by the International Technical Support Organization (ITSO), Poughkeepsie Center. It provides students of information systems technology with the background knowledge and skills necessary to begin using the basic facilities of a mainframe computer. For optimal learning, students are assumed to have successfully completed an introductory course in computer system concepts, such as computer organization and architecture, operating systems, data management, or data communications. They should also have successfully completed courses in one or more programming languages, and be PC literate. This textbook can also be used as a prerequisite for courses in advanced topics, or for internships and special studies. It is not intended to be a complete text covering all aspects of mainframe operation. It is also not a reference book that discusses every feature and option of the mainframe facilities. Others who can benefit from this course include experienced data processing professionals who have worked with non-mainframe platforms, or who are familiar with some aspects of the mainframe but want to become knowledgeable with other facilities and benefits of the mainframe environment. As we go through this course, we suggest that the instructor alternate between text, lecture, discussions, and hands-on exercises. Many of the exercises are cumulative, and are designed to show the student how to design and implement the topic presented. The instructor-led discussions and hands-on exercises are an integral part of the course, and can include topics not covered in this textbook. In this course, we use simplified examples and focus mainly on basic system functions. Hands-on exercises are provided throughout the course to help students explore the mainframe style of computing. At the end of this course, you will be familiar with the following information: Basic concepts of the mainframe, including its usage and architecture Fundamentals of IBM z/VSE® (VSE), an IBM zTM Systems entry mainframe operating system (OS) An understanding of mainframe workloads and the major middleware applications in use on mainframes today The basis for subsequent course work in more advanced, specialized areas of z/VSE, such as system administration or application programming

Book excerpt: Welcome to the proceedings of the 2010 International Conferences on Grid and D- tributed Computing (GDC 2010), and Control and Automation (CA 2010) – two of the partnering events of the Second International Mega-Conference on Future Gene- tion Information Technology (FGIT 2010). GDC and CA bring together researchers from academia and industry as well as practitioners to share ideas, problems and solutions relating to the multifaceted - pects of high-performance and compound control systems, including their links to computational sciences, mathematics and information technology. In total, 1,630 papers were submitted to FGIT 2010 from 30 countries, which - cludes 198 papers submitted to GDC/CA 2010. The submitted papers went through a rigorous reviewing process: 395 of the 1,630 papers were accepted for FGIT 2010, while 40 papers were accepted for GDC/CA 2010. Of the 40 papers, 8 were selected for the special FGIT 2010 volume published by Springer in LNCS the series. 28 papers are published in this volume, and 4 papers were withdrawn due to technical reasons. We would like to acknowledge the great effort of the GDC/CA 2010 International Advisory Boards and members of the International Program Committees, as well as all the organizations and individuals who supported the idea of publishing this volume of proceedings, including SERSC and Springer. Also, the success of these two c- ferences would not have been possible without the huge support from our sponsors and the work of the Chairs and Organizing Committee.

Download or read book CICS Transaction Server from Start to Finish written by Chris Rayns and published by IBM Redbooks. This book was released on 2011-12-07 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this IBM® Redbooks® publication, we discuss CICS®, which stands for Customer Information Control System. It is a general-purpose transaction processing subsystem for the z/OS® operating system. CICS provides services for running an application online where, users submit requests to run applications simultaneously. CICS manages sharing resources, the integrity of data, and prioritizes execution with fast response. CICS authorizes users, allocates resources (real storage and cycles), and passes on database requests by the application to the appropriate database manager, such as DB2®. We review the history of CICS and why it was created. We review the CICS architecture and discuss how to create an application in CICS. CICS provides a secure, transactional environment for applications that are written in several languages. We discuss the CICS-supported languages and each language's advantages in this Redbooks publication. We analyze situations from a system programmer's viewpoint, including how the systems programmer can use CICS facilities and services to customize the system, design CICS for recovery, and manage performance. CICS Data access and where the data is stored, including Temporary storage queues, VSAM RLS, DB2, IMSTM, and many others are also discussed.
