Objectives

This course explains two 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. This course covers both of these concepts explaining what they are and how they can be best exploited.

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

• explain the concept of Sysplex
• describe the XCF function for connecting the systems
• explain how Data Sharing works
• describe Sysplex management
• explain what the IRD does
• exploit WLM LPAR CPU management
• exploit Dynamic Channel-path management
• exploit CSS I/O priority management.
