Abstract
A system and method is described for use with a data grid cluster to support death detection. A network ring is formed by connecting a plurality of process nodes in the data grid, wherein each node in the network ring watches another node. A death of a first process node in the network ring can be detected by a second process node, when the second process node notices that its connection to the first process node has closed. The first process node then informs other process cluster nodes in the network ring that the first node is dead. In accordance with an embodiment, machine level death detection can also be supported in the data grid cluster by using an Internet Protocol (IP) monitor.
