Implementing a Parallel Sysplex - A Practitioner Series Course Offering Copyright © 1999 Mentor Services Corp - 200 White Plains Road - Tarrytown - NY 10591.

Introduction: Beginning with MVS/ESA™ version 5, IBM set the stage for the definition and operation of a Parallel Sysplex® (system complex). The Sysplex consists of two or more independent OS/390 systems connected through a Coupling Facility, which makes it possible for these systems to share key system operational and performance data. Most importantly, the parallel sysplex permits the cloning of key applications (such as CICS, DB2 and IMS) and distributing these clones across the sysplex members. This provides the installation a new, high availability option for these applications. Because of the data sharing between these applications through the coupling facility, files can be shared with update integrity, providing an application that has no single point of failure. This course teaches the principles of the sysplex, describes the mechanisms that establish and support it, and explains how the OS/390 systems programmer goes about configuring its facilities to provide the high-availability option to distributed (cloned) applications. It also covers the strategies and implementation methods for recovery and performance in a parallel sysplex. Audience: All system programmers who are required to implement an OS/390 parallel sysplex. Objectives:  On completion of this course, the student should be able to: Identify the key components of an OS/390 sysplex and describe their functions Define the sysplex configuration to the operating system Enter commands to control and dynamically reconfigure the sysplex Identify performance and recovery problems in the sysplex and correct them Define sysplex recovery policies Prerequisites: The student must have prior experience installing OS/390 systems or system products. Duration: This course is 2 days long.
