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.

This IBM® Redbooks® publication provides information to help clients that have JES3 and want to migrate to JES2. It provides a comprehensive list of the differences between the two job entry subsystems and provides information to help you determine the migration effort and actions. This book considers the features of JES2 as available on releases of IBM z/OS® V2R3 and V2R4. It should be used with JES3 to JES2 Migration Considerations, SG24-8083. This publication is divided into three parts: Part 1, "Planning to migrate from JES3 to JES2" on page 1, gives you information to make the decision and plan your migration. Part 2, "Use case study" on page 111, provides a Use Case Study that is based on an actual customer experience in a successful migration. Part 3, "Appendixes" on page 193, provides an appendix with sample tools that can help the migration process and exploitation of some of the new JES2 functions. This book is aimed at operations personnel, system programmers, and application developers

A major goal of operating systems is to process jobs while making the best use of system resources. Thus, one way of viewing operating systems is as resource managers. Before job processing, operating systems reserve input and output resources for jobs. During job processing, operating systems manage resources such as processors and storage. After job processing, operating systems free all resources used by the completed jobs, making the resources available to other jobs. This process is called resource management. There is more to the processing of jobs than the managing of resources needed by the jobs. At any instant, a number of jobs can be in various stages of preparation, processing, and post-processing activity. To use resources efficiently, operating systems divide jobs into parts. They distribute the parts of jobs to queues to wait for needed resources. Keeping track of where things are and routing work from queue to queue is called workflow management, and is a major function of any operating system. JES3 considers job priorities, device and processor alternatives, and installation-specified preferences in preparing jobs for processing job output. This IBM® Redbooks® publication describes a JES3 environment that includes the following: - Single-system image - Workload balancing - Availability - Control flexibility - Physical planning flexibility.

This text overcomes the limitations of most of the technical literature concerning JCL by providing comprehensive examples and practical guidance throughout. The text focuses on the functional, relevant topics programmers need to know to get work done in a business data processing environment. Examples start with what a programmer needs to know to test a job, then builds up to what must be done to move the job into production. This learn-by-doing approach also shows how JCL is integrated with online facilities such as TSO. Features a complete summary of contemporary system completion codes with advice for problem resolutions and fresh coverage of condition code testing, generation data group creation and usage, and more. No Comb binding.
