IBM (z/OS) – Working with the Mainframe 2.5


3 hours



This course begins by explaining how data is stored in a mainframe and the type of security that protects it. It then discusses the core products used to prioritize and process that data. Locating system documentation is going to be important for anyone working on the mainframe, for example error message manuals, product installation processes, so knowing how to access it is important. This is covered in the last module of this course.


This course is designed for any personnel that are required to have a broad understanding of the IBM mainframe environment.

After completing this course, the student will be able to:

  • Describe how to access and interact with the mainframe
