What You Can Expect

This course will introduce delegates to the z/OS operating system and the IBM systems on which it runs. It covers common z/OS terminology and explains the main concepts employed by z/OS in performing its functions, before moving on to the TSO functionality and JCL Commands that are essential for all users of the z/OS Operating system.

Delegates will:

  • Understand the history and make-up of the IBM System z and z/OS operating system.
  • Log-on to TSO and control the TSO session.
  • Navigate the ISPF panels.
  • Create, edit and view data sets and members within PDS and PDSE libraries.
  • Perform general utility functions from within ISPF.
  • View and manage job output using SDSF.
  • Code JCL to perform general tasks within the z/OS system.
  • Understand the Job listings and associated messages.
  • Diagnose and resolve JCL problems.
  • Analyze Job failures, correct and re-start jobs.
  • Code JOB, EXEC, and DD statements.
  • Create data sets of different types.
  • Improve programmer efficiency and reduce program test time.
  • Decrease the number of job failures.
Who Should Take This Course

This course is designed for anyone requiring a complete Technical Introduction to the z/OS operating system - including TSO/ISPF and JCL.

It provides the perfect starting point for any staff moving into the world of the IBM System z from other technical backgrounds as well as those completely new to IT. Delegates requiring more in-depth training can move on to operator or developer (COBOL Programming) courses but this course is always the best way to start out.
