Abstract:
A method for communicating node liveness in a multinode data processing system employs an operating system function that provides a degree of self-awareness in “sensing” an imminent but still pending failure as the basis for providing special flag signals over a channel which employs nonvolatile storage in a heartbeat signaling path.
