The essential introduction to z/OS, this course provides a firm technical view of IBM's z Systems mainframe environment, with the emphasis on z/Architecture and z/OS, IBM's strategic mainframe operating system.
The course also provides an overview of all the associated software and system components that comprise the complete system.

This course is also available for one-company, on-site presentations and for live presentation over the Internet, via the Virtual Classroom Environment service.

Attendance of the course IBM z Systems - Explained or equivalent knowledge is recommended, as is an understanding of TSO and JCL.

  • describe the mainframe hardware components
  • explain how I/O components are configured and used
  • describe the main features of z/OS and its associated system software
  • explain the relationship between the hardware and software
  • explain the relationship between MVS and its associated components
  • understand how to use an MVS system via TSO and batch jobs
  • describe how data is managed by SMS.
