| IMS/ESA Data Sharing in a Parallel Sysplex, SG24-4303-00 | | ||||
| |||||
| Abstract |
| |
| IMS/ESA Version 5 was the first MVS subsystem to support data sharing in the Parallel Sysplex environment and IMS/ESA Version 6 introduces many important enhancements. Both levels interact with the new MVS workload manager. This publication focuses on the implementation of the facilities associated with IMS/ESA in a Parallel Sysplex environment and provides implementation guidelines, recommendations, and migration options. We explain the basic concepts of a parellel sysplex and how IMS takes advantage of them to deliver N-way data sharing. We make you aware of the new features of components such as IRLM and DBRC and highlight some of the performance and availability issues you should be aware of. This document was written for systems, application design, database administration, operations and performance people who are involved in design, implementation, operation and tuning of Parallel Sysplex and data sharing systems. The intent of this publication is to provide the necessary information to plan for your migration to IMS data sharing in a Parallel Sysplex environment, with an understanding of the new enhancements to IMS and other products and an appreciation of the configuration, design recommendations, performance considerations, and implantation steps involved. Knowledge of IMS/ESA Version 5 in a non-data-sharing environment is assumed. | |
