z/OS Internals Boot Camp

Mainframe Training Overview

This course provides a detailed examination of z/OS for systems programmers. Topics include an introduction to z/OS architecture, system services and functions, storage management mechanisms, and I/O processes. Each section will also explore the associated control block structures associated with the z/OS operations being looked at. In addition, the student will become familiar with using the z/OS Data Areas documentation, and analyzing numerous dumps and trace data to gather information about problems.

Mainframe Training Audience

Experienced systems programmers with a need for a more detailed understanding of z/OS functions. Due to the technical nature of this material, the student should have several years experience in the z/OS environment.

Mainframe Training Course duration

10 days
