摘要：In at least one example embodiment, the invention relates to a computer-implemented method, a computer-implemented system and a computer program product for controlling the access to splittable resources in a distributed client server system operating in parallel. The resource control system is designed for a plurality of clients connected to the system and is used to maintain consistency of the data. When a client makes a first attempt to access a resource of the server, an exclusive lock for the requested resource is allocated to the accessing client, that blocks the access to the resource for other clients, said exclusive lock only being allocated for a pre-determinable period of time and then automatically discontinued.
