Abstract
A concurrency control mechanism for a client/server computing system analyzes each client request to determine whether it can be given concurrent access to a server's resources, along with other client requests which are presently accessing the server's resources. Each client request triggers the setting up of a lock request mode which contains conflict resolution logic based on the particulars of the corresponding request. When a new request comes in, the new request's newly created lock request mode is compared to the lock request modes of the previous requests which are currently accessing the server's resources and the conflict resolution logic is carried out to determine whether the new request should be also allowed access.
