(a 3-day course)
After the training the students will have the basic theoretical knowledge necessary for every IBM mainframe
This course should to be seen as an introduction course which is necessary for further classes.
On the other hand this training will cover all fundamental Concepts and terminology of OS/390 and z/OS which will enable
the participants to consult the OS/390 and z/OS literature independently.
During the class do we explain the 'how' but also the 'why' of OS/390 and z/OS functionality.
