Objectives

This course follows on from the course UNIX System Services Concepts & Facilities. It teaches the skills needed to install, configure and implement UNIX System Services in a z/OS environment. The course goes on to describe and explain how to manage the new environment efficiently and effectively.

On successful completion of this course, attendees will be able to:

• plan the installation and implementation of USS
• implement USS
• customisze USS
• maintain the HFS environment
• describe the constraints on USS
• apply RACF security to the environment
• manage a USS environment.
