MVS/ESA coupled-systems considerations
Mitchell D. Swanson, C. P. Vignola · IBM Journal of Research and Development · 1992
One of the most important future MVS environments will be to provide on-line transaction processing and decision support through the use of large data “warehouses” in heterogeneous networks. To provide the large capacity and high availability required for this environment, it will be necessary to use multiple, cooperating MVS systems to provide those services. The design of such coupled MVS systems must accommodate a number of factors related to both the general environment and the user's needs, including availability, growth, granularity and scale, systems management, migration and coexistence, and single-system images. In this paper, we describe the system services available with MVS/ESA™ SP Version 4 that can support the coupled-systems environment, and discuss how those services can be exploited.
