Introduction to IMSplex connectivity. 327 $a10.1 IMS connections. 330 $aThis IBM Redbooks publication is the first volume of a series of redbooks called IMS in the Parallel Sysplex. These redbooks describe how IMS exploits the Parallel Sysplex functions and how to plan for, implement, and operate IMS systems working together in a Parallel Sysplex. Volume 1 provides an overview of the Parallel Sysplex and the services offered to authorized programs such as IMS. It then continues with the description of the functionality that IMS provides in a Parallel Sysplex environment. Each function supported by IMS is presented in one or more chapters. The topics include: - Introduction to the Parallel Sysplex - Block level data sharing - Connectivity and workload balancing - Shared queues - Common Service Layer The other volumes in this series are: IMS in the Parallel Sysplex, Volume II: Planning the IMSplex, SG24-6928 IMS in the Parallel Sysplex, Volume III: IMSplex Implementation and Operations, SG24-6929 410 0$aIBM redbooks. 517 3 $aReviewing the IMSplex technology 606 $aIMS/VS (Computer system) 606 $aParallel computers 606 $aParallel processing (Electronic computers) 606 $aDatabase management 615 0$aIMS/VS (Computer system) 615 0$aParallel computers. 615 0$aParallel processing (Electronic computers) 615 0$aDatabase management. 676 $a004/.35 700 $aJa?ntti$b Jouko$01890432 701 $aMartinez$b Juan Jesus Inlesta$01890825 701 $aKubein$b Knut$01890826 701 $aStillwell$b Bill$01890731 701 $aWicks$b Gary$01890732 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910954980403321 996 $aIMS in Parallel Sysplex$94533198 997 $aUNINA
