This IBM Redbooks publication is the third volume of a series of redbooks called IMS in the Parallel Sysplex. These redbooks describe how IMS exploits the Parallel Sysplex functions and how to plan for, implement, and operate IMS systems working together in a Parallel Sysplex. This book encompasses two parts. Part 1, Implementation, is a description of the tasks an IMS installation must execute to enable each of the functions. Part 2, Operations, addresses the operational issues associated with running an IMSplex that include startup and shutdown, steady state operations, online change, and recovery from failure. IMS in Parallel Sysplex, Volume I: Reviewing the IMSplex Technology, SG24-6908

This IBM Redbooks publication is the first volume of a series of redbooks called IMS in the Parallel Sysplex. These redbooks describe how IMS exploits the Parallel Sysplex functions and how to plan for, implement, and operate IMS systems working together in a Parallel Sysplex. Volume 1 provides an overview of the Parallel Sysplex and the services offered to authorized programs such as IMS. It then continues with the description of the functionality that IMS provides in a Parallel Sysplex environment. Each function supported by IMS is presented in one or more chapters. The topics include: - Introduction to the Parallel Sysplex The other volumes in this series are:

In this IBM Redbooks publication, we describe the new features and functions in IMS Version 8. We document the tasks necessary to exploit the features, and identify migration, coexistence, and fallback considerations. We also identify specific hardware and software requirements that are needed to exploit certain enhancements. First we provide an overview, where we have grouped the various enhancements and their discussion into the categories availability and recoverability, performance and capacity, systems management, and application enablement. Then we have more detailed chapters for describing the individual enhancements. The base enhancements part of the book describes the base product enhancements that apply to all users migrating to IMS Version 8. The Parallel Sysplex enhancements part of the book describes enhancements in IMS Version 8 that apply to both existing users of IMS Version 6 or IMS Version 7 in a Parallel Sysplex environment and users that are considering sysplex functionality. The Common Service Layer part documents the Common Service Layer (CSL), new in IMS Version 8, which is the next step in IMS Parallel Sysplex evolution. The CSL enables IMS systems to operate in unison in an OS/390 Parallel Sysplex. The CSL components provide the infrastructure for an IMSplex.
