Description

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

  • I/O infrastructure and processor usage: zEC12 to z10 comparisons

  • 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
