Objectives

This course explains important concepts that are dependent on zSeries hardware features. The advent of Parallel Sysplex architecture and its supporting components within MVS have made the zSeries platform extremely resilient and scalable. In addition to this, the concept of the LPAR has been extended by the Intelligent Resource Director, allowing the power of the zSeries features to be directed to where it is most needed.

The course also describes and explains the components of the parallel sysplex concept and covers data sharing, installation, IPL, components & services and sysplex exploitation.

On successful completion of this course, attendees will be able to:

• explain concepts such as HCD, HSM and SMS
• explain what the IRD does
• exploit WLM LPAR CPU management
• exploit Dynamic Channel-path management
• exploit CSS I/O priority management.
• explain the concept of sysplex
• explain the reasons for the introduction of the parallel sysplex concept
• explain the business implications of the parallel sysplex
• describe the XCF function for connecting the systems
• explain how Data Sharing works
• describe Sysplex management
