This course, and its associated Part 1, together form the heart of the z/OS training curriculum for Systems Programmers.<br>In this second course, attendees learn the functions of the major z/OS components in considerable detail, and learn how the interaction of job, task, storage and data management provides service to the end user. This is done by following the sequence of events as a unit of work passes through the z/OS system from initial submission to completion.<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.

For corporate groups, we can organize this training as an on-site private group.
