z/OS System Operation and Facilities


Duration: 5.0 days

Method: Instructor led, Hands-on workshops

Price: $3250.00

Course Code: MF3010


System programmers, operators, and application programmers that need an understanding of the z/OS environment and the subsystems supported. Workstations will be used to illustrate concepts and provide basic exposure to the elements of the z/OS environment.


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.
