z/OS System Operation and Facilities
Mainframe Training Overview
This course provides an examination of z/OS for systems programmers, operators and application programmers. Topics include an introduction to the z/series systems hardware and an exploration of z/OS architecture, system services and functions, storage management mechanisms, and I/O processes. In particular the focus will be to explore the operation of the z/OS environment with an objective of understanding its performance and exploitation opportunities.
System programmers, operators, and application programmers that need an understanding of the z/OS environment and the subsystems supported.
