Practical MVS JCL for Today's Programmer


Book Description

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.




Practical VSAM for Today's Programmers


Book Description

Written by authors who design, program, and manage online systems supported by VSAM data sets, this text is intended to train readers -- particularly, business data processing programmers -- to use VSAM in a practical manner. Covers thoroughly the VSAM key sequenced data set knowledge and techniques needed to operate productively in the business data processing environment. Illustrates tools in documented source code form -- computational CLISTs, programs that read LISTCATs and automatically extract and analyze them, and prime or alternate key value distribution analysis routines (diskette available for uploading to mainframe). Also addresses management of VSAM data sets in the production environment.




Practical MVS JCL Examples


Book Description

Revised to be a companion/reference to Gary Brown's System 370/390 JCL, known as the ``JCL Bible,'' it contains a significant amount of actual JCL examples in the context of a single large model program, added upon as each new feature of JCL is introduced. Details the latest enhancements from IBM including MVS/ESA and SMS. Demonstrates debugging techniques through JCL. Illustrations are in TSO/ISPF with JCL to make the book's screen examples look exactly like those seen on a computer.

Operating Systems


Book Description

B> The fifth edition of Operating Systems: A Systematic View offers a practical and applied introduction to operating system concepts, aimed at people interested in using computers, operating systems, and networks. The authors take a "systematic view" of the subject, where they provide insight into what is going on beneath the surface instead of focusing so much on OS theory. The intent is to show why operating systems are needed and what, at a functional level, they do. The book features an engaging, reader-friendly presentation written at a pace and level appropriate for novices, and contains extensive illustrations to visually reinforce concepts. Readers are guided through some of today's most widely used operating systems, including Linux, UNIX, and Windows 2000. Also included is coverage of several modern topics and technologies, with chapters on the Windows interface, Intel Pentium architecture, and Windows internals, as well as a section on network operating systems with chapters on client/server networks, Windows 2000, Novell, and the Internet. This book is designed for people from non-technical fields and backgrounds who simply need to know how to interact with, rather than how to design, an operating system. It requires no background in programming and only a working knowledge of basic algebra. It will also be of interest to computer programmers, technical managers, and applied practitioners who want a practical and applied introduction to operating systems.




Introduction to Operating Systems


Book Description

This text aims to provide a firm foundation in the principles and concepts of operating systems design and discuss major issues, as well as to show how several operating systems have implemented these concepts. It covers all major topics of operating systems, including memory management, I/O processing, concurrent processing, auxiliary storage management, and scheduling. There is also a chapter on queuing theory and a chapter with four case studies: MS-DOS, UNIX, VMS, and MVS. Additional case studies are presented at the end of each chapter.
