z/OS Foundation Skills - Boot Camp


This five-day Boot Camp course is the essential introduction to the IBM z Systems enterprise computing environment and its flagship operating system, z/OS. The course introduces the concepts and terminology encountered and used by IS personnel every day, and explains them in an easily understandable manner.

The concepts, facilities and use of TSO and IBM's Interactive System Productivity Facility (ISPF) are taught during this week, with a focus on the functions for data editing and dataset management. The week concludes with an introduction to z/OS Job Control Language (JCL). Attendees will be introduced to the coding of job control statements to execute programs and access datasets in a z/OS environment. They will also learn how to write and test catalogued procedures. Throughout the week the formal classroom teaching is combined with an engaging and progressive series of hands-on practical sessions using a variety of IBM utilities.

This course is available 'On Demand' (minimum 2 students) and is also available for one-company, on-site presentations.

Objectives

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

  • identify the principal components of IBM z Systems
  • describe how data is stored, the different data codes and types, and the devices used
  • explain the concepts of operating systems
  • use basic TSO commands
  • use and customise ISPF panel structures
  • browse and edit datasets
  • customise ISPF edit profiles
