This course examines the performance issues that occur when using a parallel sysplex. Processor architecture and the impact of various configurations will be presented. The Coupling Facility, which forms the basis of IBM's unique method for high-speed data-sharing across all systems, is discussed at length and in significant detail. The course begins with an introduction to performance management that examines the terminology, components and issues unique to a parallel sysplex.. The presentation then moves into the details of analysis, monitoring, and tuning a parallel sysplex environment.
