Recovery of a name server managing membership of a domain of processors in a distributed computing environment |
摘要 |
Recovery of a name server managing membership of a domain of processors in a distributed computing environment which includes detecting the failure of the name server node and consulting a membership list of nodes in the domain to determine the crown prince (CP) node who is next in line to become the name server. The other available nodes in the domain periodically send recover messages to the CP node, and responsive to receiving the recover messages from all the other available nodes in the domain, the CP node perform a two phase takeover whereby the CP node becomes the name server for managing said processors in the domain. After the CP node becomes the name server, the other available nodes in the domain send data to the new name server necessary for the name server to manage the other available nodes in the domain. All request messages requesting management by the name server are stored locally until after the CP becomes the name server. The locally stored request messages are then processed by the other available nodes such that no request messages are lost during recovery. |
