This course is designed to provide an understanding of today's complex system mainframe environment on the zEnterprise System and System z servers. It is mainly targeted for operators technical support, system programmers, and any others who need to keep current in this mainframe environment. Through lecture and hands-on exercises, you learn how the hardware and operating systems interact.

This course addresses the following topics:

  • Mainframes and distributed server comparisons: Why so many servers-
  • Mainframe directions: Past, current, and future
  • Mainframes: System z introduction and relative performance comparisons
  • IBM System z hardware design: Frames, CEC cage, books, models, and MSUs
  • System z Capacity on Demand
  • Physical/Logical partitioning, server initialization, and CHPIDs
  • I/O configuration and HCD overview
  • MVS to z/OS software overview
  • z/OS Parallel Sysplex
  • z/OS enhancements on the zPlatform
  • z/Architecture overview and virtual addressing concepts
  • System concepts: The big picture
  • HMC introduction, groups, and activation profiles
  • Determining object status and error conditions
  • Activation and operating system interface

A nice, albeit dense, course that runs through a lot of key AWS services and concepts.

the class was setup very well and I feel that I will be able to take what I have learned and use.

es la primera vez que se toma un curso con ExitCertified y ha sido una buena experiencia

The course is well organized, and I would recommend it. The cadence can be faster.

The lady at the front really nice. Everthing was always stocked up: Helpful
