DB2 for z/OS can also run in a Parallel Sysplex environment. This environment is a requirement to support DB2 data sharing. Parallel Sysplex technology provides for an environment in which several processors can share data and the DB2 subsystems can have concurrent read/write access to the data. DB2 V4, data sharing allows read-write access to DB2 data from different DB2s residing in multiple CPCs in a parallel sysplex. DB2 data sharing in a parallel sysplex provides much better performance than distributed data. The coupling facility is the vehicle allowing data base managers and MVS components to share this data using the.

Period. IMS is not mentioned in the news and, until fairly recently, was barely mentioned.
The Parallel Sysplex Support (PSS) component allows you to perform snapshot processing in a DB2 sysplex or IMS data sharing environment. When the PSS component is active and running in a sysplex, EXTENDED BUFFER MANAGER (XBM) subsystems communicate within the sysplex group and monitor shared table spaces. This IBM® Redbooks® publication pulls together diverse information regarding the best way to design, implement, and manage a Parallel Sysplex® to deliver the levels of performance and availability required by your book should be of interest to system programmers, availability managers, and database administrators who are interested in verifying that your systems .

of a parallel sysplex data sharing project using IMS/ESA Version 5, IMS Resource Lock Manager (IRLM) Version 2, and MVS/ESA Version at Amalgamated Banks of South Africa (ABSA) located in Johannesburg South Africa.
The steps that were taken to plan, prepare and implement this project. The foundation in using Parallel Sysplex with IMS is the implementation of data sharing by IMS DB. Data sharing allows multiple IMS subsystems to access and update the same IMS databases.
Block-level data sharing means that each IMS server has the authority to access and update all shared data. As many as IMS subsystems on up to 32 z/OS. Both of the parts are divided into chapters addressing the sysplex services exploited by IMS to support block level data sharing, connecting to the IMSplex, shared queues, and the systems management functions enabled with the Common Service Layer introduced in IMS Version 8 - operations management and resource management.
In computing, a Parallel Sysplex is a cluster of IBM mainframes acting together as a single system image with z/ for disaster recovery, Parallel Sysplex combines data sharing and parallel computing to allow a cluster of up to 32 systems to share a.

All z/OS, zOS.e, OS/ and MVS/ESA V5 images that comprise the Parallel Sysplex environment must have at least one common systems enablement function activated to use the Coupling Facility across all images in the sysplex.
Eligible systems enablement functions are listed below: A. Application Data Sharing including: a. IMS/TM: with IMS DB. In the early days of sysplex, the norm was 1 z/OS = 1 DB2.
With a max of 32 systems in a sysplex, it was natural to assume a maximum of 32 DB2s in a data sharing group. For various reasons, we now see cases where many DB2 subsystems from the same data sharing group reside in the same z/OS system.
Each function supported by IMS is presented in one or more chapters. The topics include: Introduction to the Parallel Sysplex - Block level data sharing - Connectivity and workload balancing - Shared queues - Common Service Layer The other volumes in this series are: IMS in the Parallel Sysplex, Volume II: Planning the IMSplex, SG IMS.
