ABSTRACT:
Managing membership of a domain of processors in a distributed computing environment including determining the lowest numbered node available in the domain and periodically sending grovel messages from the other available nodes to the lowest numbered node in the domain. Responsive to receiving all of the grovel messages by the lowest numbered node, the lowest numbered node performs a two phase commit whereby the lowest numbered node becomes a name server for managing the processors in the domain. The two phase commit includes sending an insert phase 1 (P1) message to the other available nodes from the lowest numbered node and, responsive to the insert P1 message, sending an acknowledge (ACK) message from the other available nodes to the lowest numbered node. Responsive to the ACK messages, a commit message is sent to the other available nodes notifying them that the lowest numbered node has become the name server.
