ABSTRACT:
Disclosed is a system, method, and program for transferring data. When a transaction commits, multiple data objects that have been changed by the transaction are identified. The multiple data objects are written from local storage to a cache structure using a batch write command. When changed data objects at a first system that are not cached in the shared external storage are written to disk, a batch cross invalidation command is used to invalidate the data objects at a second system. Additionally, multiple data objects are read from the cache structure into a processor storage using a batch castout command.
