Mainframe Training Overview
This course presents the features, functions, and requirements for running in the Parallel Sysplex environment. Capabilities of z/series processors are reviewed regarding how each participates in the Parallel Sysplex configuration. 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 a high-level introduction that examines the terminology, components and architectural aspects of a parallel sysplex.. The presentation then moves into the details of management and operation of a parallel sysplex environment.
Systems Programmers, Technical Support and anyone who wants a better understanding of the technical issues associated with the Parallel Sysplex.
Workstations are needed for this session. Prerequisites: Understanding of OS/390 and/or z/OS fundamentals.
