z/OS Boot Camp

SEE SCHEDULE

Duration: 10.0 days

Method: Instructor led, Hands-on workshops

Price: $6000.00

Course Code: MF4000



Audience

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.

Description

This course provides an intense examination of z/OS for systems programmers. Topics include an introduction to computer systems hardware and an exploration of architecture, system services and functions, storage management mechanisms, and I/O processes. Additional topics include REXX programming, SMP/E processing, an overview of Workload Manager and performance tuning. In the final section a look at system diagnostics and data collection will be examined.

Prerequisites

Student should have a familiarity with TSO/ISPF, JCL, and MVS fundamentals. Given the material covered, the student should have a reasonably good sense of MVS (z/OS) before attending. It is intended as a “bootcamp” for systems programmers and not an introduction.
