What You Can Expect

This course 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. At the end of the course the delegate will be able to perform the following activities:

  • Use TSO ISHELL to create and view UNIX files and directories, perform data transfer between z/OS data sets and UNIX files.
  • Use TSO commands to create and view UNIX files and directories, perform data transfer between z/OS data sets and UNIX files.
  • Use UNIX commands to create and view UNIX files and directories, perform data transfer between z/OS data sets and UNIX files.
  • Use JCL to perform batch functions running UNIX shell scripts. Set up UNIX Services on z/OS.
  • Monitor and control UNIX on z/OS.
  • Set up and maintain HFS and zFS file systems in both a single system and in a shared HFS within a SYSPLEX.
  • Set up and administer UNIX users.
Who Should Take This Course

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.

Recommended 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.
