ABSTRACT:
A method of controlling entry of a block of data is used with a high-speed cache which is shared by a plurality of independently-operating computer systems in a multi-system data sharing complex. Each computer 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 high-speed cache assures that the block of data entered into the cache will not be overwritten by an earlier version of the block of data obtained from the upper-level storage.
