ABSTRACT:
An automatic failure notification mechanism for use in a computer network wherein several co-operating parts of an application program are each running on a different node of the computer network. The mechanism comprises a set of linked subroutines called by each part of the application program and operating through the use of a distributed lock manager to designate one part as a part to receive failure notification and to link and reverse link the selected part and the other parts of the application program. The failure notification mechanism utilizes the link and reverse link to initiate a failure communication upon the failure of a node executing one part of the application program.
