BMC Mainframe: z/OS System Anatomy Part 1 - z Architecture
The course is developed and delivered by © RSM Technology.
This course and the follow-on Part 2 course together form the essential core of RSM's 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 z/OS, enabling further skills enhancement in areas such as debugging, performance, installation and customisation of the operating system.
This course concentrates on laying the ground rules of z/OS in terms of architecture and storage management, as well as explaining the major control blocks and how to interpret them. The course also introduces the major components found in today's Z Systems environments.
