Abstract: A server concurrency control technique for use in a client/server computing system where a client sends a request to a server for access to a server resource involves receiving client requests of a plurality of lock requester types at a lock requester interface; comparing each of said requests against a lock requester set which has a lock requester type representation corresponding to a lock requester type of previously received client requests which are presently holding locks to server resources; and as a result of the comparing step, determining whether a newly received client request conflicts with previously received client requests which are currently holding locks to server resources.
