ABSTRACT:
A dead lock releasing method automatically releases a dead lock state in a data processing system, wherein a plurality of kinds of tasks selectively use a plurality of common resources. When one task X occupies a resource A and, in this state, the task is to occupy a resource B, if the resource B is occupied by another task Y, the task X is placed in a waiting state. When the task X is placed in a waiting state based on the occupation of the resource B by the task Y and the task Y, which is to occupy the resource A, is placed in a waiting state based on the occupation of the resource A by the task X, the task X and the task Y are placed in a dead lock state. When the dead lock state is caused between the tasks X and Y, the occupation of the resource A by the task X is released and the processing of the task Y is carried out. Then the processing of the task X is carried out.
