Abstract
A datagram messaging service for a distributed lock manager implemented on a clustered computer system including a plurality of processing nodes interconnected through a network. The messaging service establishes and maintains a plurality of virtual circuits between the processing nodes, a single virtual circuit connecting each pair of processing nodes within the clustered computer system. A distributed lock manager driver is included within each processing node, the driver including a communication service providing for the generation of datagrams comprising lock manager instructions for transmission to other processing nodes within the clustered computer system via said virtual circuits and also providing for the receipt of datagrams generated and transmitted by the other processing nodes.
