UNIX Implementation and Use on z/OS

Course Overview

This course is based on z/OS Version 1 Release 7 and provides the participant with an overview of UNIX Services in a z/OS system. It concentrates on the non-UNIX facilities available in z/OS to perform UNIX type work

Audience

This course is for anyone within an existing z/OS installation who requires an appreciation of UNIX and how it fits into an existing z/OS operating system. z/OS system programmers and system administration staff who are responsible for implementing and/or maintaining UNIX on a z/OS system, should also attend this course. It is also for UNIX professionals who are implementing UNIX and UNIX applications on a z/OS system and need to understand the environment.

Prerequisites

Delegates should be familiar with z/OS, TSO and JCL. This knowledge can be obtained from our z/OS for Beginners, TSO/ISPF Workshop and z/OS JCL courses.
