Abstract
A high-speed cache is shared by a plurality of independently-operating data systems in a multi-system data sharing complex. Each data system has access both to the high-speed cache and to lower-speed, upper-level storage for obtaining and storing data. Management logic in the shared high-speed cache is provided to meet the serialization and data coherency requirements of the data systems when sharing the high speed cache as a store-multiple cache in a multi-system environment.
