It is intended for installation managers and system programmers responsible for assessing the effort required to install an OS/VS2 Release 2 system. Readers should have a background in programming and maintaining computer operating systems such as OS/MVT or OS/VS2 Release l. This publication is for planning purposes only. The functions and capabilities described reflect the information that is currently available. This information is subject to change before the availability of OS/VS2 Release 2. Throughout this publication the term MVS is used interchangeably with VS2 Release 2. MVS refers to the mUltiple virtual storage concept of this release. This manual contains the following independent chapters: • Introduction -- The Introduction highlights the major points that should be considered in planning for the installation and implementation of VS2 Release 2. • Defining the System -- This chapter provides preliminary planning information for defining the type of system that an installation needs. For example, the chapter describes the VS2 Release 2: --procedures and macro instructions for system generation. --procedures and parameters for system initialization. --system libraries and data sets. For each topic, a summary of the major changes from both MVT and VS2 Release 1 is provided. • Directing the Use of System Resources -- This chapter describes some of the new VS2 Release 2 facilities that allow an installation to control the distribution of system resources among system users. It provides planning information that helps assess the effort involved in implementing these facilities. • System Integrity -- This chapter discusses integrity in a multi-user computer system. It includes recommendations for maintaining, in any control program extensions or modifications, the same level of system integrity as that of the VS2 Release 2 system. • Conversion Considerations -- This chapter presents preliminary descriptions of some of the most significant differences between VS2 Release 2 and MVT or VS2 Release 1. It provides the information to assess the extent of the modifications required for existing data sets, cataloged procedures, programs, data reduction routines, and operational procedures, to install VS2 Release 2. • Appendix A: Virtual Storage Map -- This appendix shows the layout of virtual storage in VS2 Release 2. • Glossary -- The glossary describes VS2 terms. Preface 3 The following items are described in this publication strictly for advance planning purposes and will not be available with the initial release of VS2 Release 2: • lES] job entry subsystem. • Virtual telecommunications access method (VT AM). Additional information about these items will be available later. Availability dates for the support of the items may be obtained from th{! local IBM branch offices ..

After studying this lesson they will be familiar with: 1. What is an operating system? 2. Important functions performed by an operating system. 3. Different types of operating systems. 1. 1 INTRODUCTION Operating system (OS) is a program or set of programs, which acts as an interface between a user of the computer & the computer hardware. The main purpose of an OS is to provide an environment in which we can execute programs. The main goals of the OS are (i) To make the computer system convenient to use, (ii) To make the use of computer hardware in efficient way. Operating System is system software, which may be viewed as collection of software consisting of procedures for operating the computer & providing an environment for execution of programs. It’s an interface between user & computer. So an OS makes everything in the computer to work together smoothly & efficiently.
