In a complex computer system in which a resource is shared by several computers, the resource is provided therein with a memory for recording the status of the resource. Each computer writes status information of the resource into the memory and also reads the status information in the memory to know the status of the resource. The memory has a record of the latest status of the resource, allowing each computer to know the latest resource status including status information revised by other computers.
