z/OS UNIX System Services part 1 - concepts & facilities

This two-day course describes and explains UNIX System Services from a technician's point of view. The principal UNIX concepts are introduced and explained, followed by a thorough examination of USS (UNIX) at a conceptual level.
The course goes on to describe the facilities available, and explains how the z/OS system environment has changed to support open system and UNIX concepts through z/OS USS.

On successful completion of this course you will be able to:

  • understand and use the terminology associated with UNIX
  • describe basic UNIX concepts
  • issue UNIX shell commands
  • identify and utilise key shell commands such as 'find', 'grep', etc.
  • explain the changes that have been made to the MVS platform in order to support applications created for a UNIX environment
  • identify the facilities and functions provided within USS
  • utilise ISHELL.
