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

Describe how and what System z physical components are used when processing instructions and performing an I/O operation

Identify System z Capacity on Demand (CoD) options available for planned and unplanned outages

Describe the CoD provisioning architecture and which servers can use it

Describe how logical partitioning is used, resource assignments and initialization activities

Describe mainframe channels, usage, and CHPID assignments

Describe the purpose and use of HCD

Identify mainframe operating systems and their supported mainframe servers:

  • Describe how the mainframe OS evolved from the System 360 servers to the current models
  • List some of the major enhancements provided by the recent z/OS versions and to what servers they apply
  • List z/OS coexistence and release support strategy
  • Describe the various queues that are used to dispatch work

  • Multiple subchannel sets, zHPF, CPM, HiperDispatch, zDAC
  • TEF, RI, DAT2, Flash Express, zAware, and autonomic computing

Identify processor architectural modes and their supported addressing implementations:

  • Bimodal, trimodal, address spaces, virtual addressing, and storage usage

Describe the various queues that are used to dispatch work

Use system commands to display active address spaces and identify their current status

Describe the high level interaction between z/OS, CSS and I/O devices during I/O processing

Describe the role of the HMC and SE for System z servers

Identify and change the HMC user interface style

Identify CPC and image objects usage on the HMC

Build and customize user-defined groups

Identify profile types, usage and assign profiles to objects

Use the Details window to determine object status and assignments
