摘要
An apparatus for dispatching client requests for execution by a server object in a heterogeneous object-oriented client/server computing environment, the apparatus has: a request-holding buffer having an input connected to a communications channel which channels the client requests to the apparatus, and an output; a plurality of parallel execution threads connected to the output of the buffer; and a semantic concurrency control means for examining the semantics of a request in the buffer and the semantics of each request presently being executed on any of the plurality of parallel execution threads, and for delaying the request from being dispatched from the buffer to an execution thread if the examined semantics of the requests indicate that such dispatch would cause conflicting access to the server object's resources.
