Today it is rare to find a System z installation that does not use IBM's UNIX System Services (USS). For security administrators and systems programmers working in a System z/USS environment, a sound understanding of how RACF works with USS is essential.<br>Designed, written and presented by specialist RACF consultants, this course introduces the USS RACF interface and describes and explains how RACF is utilised within the USS environment.<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.
