Abstract
A control method of controlling a computer for controlling a resource connected to the computer and shared by a plurality of programs included in the computer includes the steps of storing a control information ID indicating a storage area in the main memory storing control information concerning access between a certain program and the resource in an OS space of a main memory, storing the control information ID in an adaptor connected to the main memory via a bus, and taking out the control information from the storage area included in the OS space, by using the control information ID stored in the adapter. In the case where the adapter runs short of a storage area, information that the adapter runs short of a storage area in the main memory is conveyed via the bus. By using the control information thus taken out, the resource is controlled.
