Abstract: The system and methods disclosed herein relate to an improved hardware configuration for geographically dispersed data restart (“GDDR”) systems. Specifically, the teachings herein allow users to reduce the number of operating systems required to run multiple GDDR systems simultaneously by employing multitenancy principles in the system design. The embodiments cover a system for operating multiple GDDR complexes wherein the individual control systems typically required to run each GDDR complex are combined into a single logical partition. We also disclose methods and computer executable products for operating multiple GDDR complexes wherein the individual control systems typically required to run each GDDR complex are combined into a single logical partition.

Abstract: The system, products, and methods disclosed herein relate to an improved configuration for geographically dispersed data restart (“GDDR”) systems. Specifically, the teachings herein ensure a particular GDDR instance does not react to messages issued from address spaces outside of its affinity group. We use the term message “affinity group” to mean the combination of a particular GDDR instance and its set of Mainframe Enablers started tasks. By ensuring that the particular GDDR instance does not react to messages intended for recipients outside of its affinity group, we improve computer functionality and efficiency by facilitating further partitioning of the logical partition. Once the logical partition is further partitioned into additional address spaces, it is possible to run Mainframe Enablers and/or additional GDDR instances independent of the particular GDDR instance of concern.
