This course follows on from the course 'UNIX System Services Part 1 - 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, with a specific focus on security.<br><br>This course is also available for one-company, on-site presentations and for live presentation over the Internet, via the Virtual Classroom Environment service.

Attendees should have attended the course z/OS UNIX System Services Concepts & Facilities Part 1- Concepts & Facilities', or have equivalent experience.

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