Abstract: A method of performing workload management within an object-oriented client/server computing environment wherein one of a plurality of servers is chosen to satisfy a client request based on at least one workload management policy, said method, which takes place within the client, includes steps of: deciding whether a client application program has issued a request for a server to do some work; forming an extended object reference based on said request, said extended object reference having, in addition to a server address field and an object key field, at least one additional field; accessing workload management policy data based on said extended object reference; and selecting one of said plurality of servers based on said accessed workload management policy data.

Abstract: An apparatus for dispatching client requests within a server computer system, wherein the client requests are issued from at least one client computer system on a different platform from said server computer system and are passed through a communications channel to said server computer system, the apparatus comprising: a buffer having an input connected to said communications channel and an output; a plurality of parallel execution threads connected to said output of said buffer; and a scheduling means for distributing client requests stored in said buffer to said plurality of execution threads in a manner such that related client requests are sent to the same execution thread.

Abstract: In a data processing environment where a client requests a server to perform part of its processing, a method of updating the client's version of server-related data without requiring the client to be a server, includes steps of: receiving, at a control point server, a first request from the client requesting that server-related data be transferred from the control point server to the client; and in response to the first request, sending the server-related data from the control point server to the client, along with a unique bind token identifying a version number of the server-related data such that each time the server-related data changes a new unique bind token is associated with the data, where the client uses the server-related data to form a second request for the server to perform part of the client's processing, and where the client sends said bind token to the server as part of the second request.

Abstract: An apparatus for dispatching client requests for execution by a server object in a heterogeneous object-oriented client/server computing environment, has: a request-holding buffer (in 32) having an input connected to a communications channel receiving the client requests, and an output connected to a plurality of parallel execution threads 33a-c; and a semantic concurrency control means 34 for examining the semantics of a request in the buffer and the semantics of each request presently being executed on any of the threads, and for delaying the request from being dispatched from the buffer to a thread if the examined semantics of the requests indicate that such dispatch would cause conflicting access to the server object's resources.
