Abstract
This redbook presents a case study of the planning and implementation
of a parallel sysplex data sharing project using IMS/ESA Version 5, IMS
Resource Lock Manager (IRLM) Version 2, and MVS/ESA Version 5.1 at
Amalgamated Banks of South Africa (ABSA) located in Johannesburg South
Africa.
The steps that were taken to plan, prepare and implement this project
are outlined with details on challenges presented to ABSA during the
migration and the resulting implemented solutions.
This document provides IMS/ESA System Programmers, Systems and
Application Designers, Data Base Administrators and Application
Programmers who are responsible for the implementation of an IMS/ESA
parallel sysplex data sharing environment with information regarding a
case study of a migration to that environment.
Some knowledge of IMS block level data sharing, Sysplex environments
and the coupling facility, recovery procedures for failures in complex
IMS/ESA environments and the roles of IRLM and the coupling facility in
the support of IMS/ESA data sharing are assumed.
