z/OS system anatomy part 2 - z/OS infrastructure & services

This and the associated z/OS system anatomy part 1 - z Architecture form the core course of the MVS curriculum. Students obtain a solid foundation in the fundamentals of z/OS enabling further study in areas such as debugging, performance, installation, and customisation of the z/OS operating system.

In this second part, students learn the functions of the major z/OS components in some 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 final completion.
