Recovery for computer switchover in a real-time system

by Harry Nagler
A programming technique is presented which permits switching from central to stand-by computer in case of failure. Switchover is accomplished automatically and without loss of data or interruption in service. The technique is applicable to a large class of commercial real-time systems which must function in an uninterrupted manner. During the normal periods when both computers are operable, the programming system permits the second computer to be utilized independently for other data processing.
