This course and the associated Part 2 course together form the essential core of the z/OS education curriculum for z/OS Systems Programmers. By attending both components attendees will gain an in-depth insight into the fundamental structure of MVS (now z/OS), enabling further study in areas such as debugging, performance, installation and customisation of the operating system.<br>This course concentrates on laying the ground rules of z/OS in terms of architecture, storage management, as well as the major control blocks and how to interpret them. The course also introduces the major components found in z Systems environments.<br><br>This course is also available for one-company, on-site presentations and for live presentation over the Internet, via the Virtual Classroom Environment service.

We can organize this training at your preferred date and location.

Prerequisites

A good working understanding of the z/OS environment, from a technician's perspective.
