z/OS Facilities

Course Overview

This classroom course of 4 and 1/2 days introduces the base elements, optional features, and servers provided in z/OS and OS/390. It focuses on the system service facilities provided by the z/OS and OS/390 Base Control Program (BCP).

It teaches the students the function of major software base elements in the management of jobs, task, storage, data, and problems. It also addresses how these functions may be affected by the system programmer.

Students are introduced to the services provided by the servers which execute in the z/OS and OS/390 environments, such as the Communications Server and the Security Server. Installation packaging options and steps to install the z/OS and OS/390 environments are also introduced.

Audience

This class is designed for persons with a technical background in information technology, who are new to the z/OS and OS/390 platforms. It is intended for those who require an in-depth understanding of z/OS and OS/390.

Prerequisites

Basic knowledge of IS technologies. Students should be familiar with z/OS and OS/390 concepts and how these systems support the Enterprise Servers.

This knowledge can be obtained by attending ES05 - 'An Introduction to the z/OS and OS/390 Environment'. Students should also have practical experience with logging on to TSO and working with JCL. This experience can be obtained by attending ES10- 'Fundamental System Skills for z/OS and OS/390'.
