    摘要： A method for communicating node liveness in a multinode data processing system employs an operating system function that provides a degree of self-awareness in “sensing” an imminent but still pending failure as the basis for providing special flag signals over a channel which employs nonvolatile storage in a heartbeat signaling path.

    摘要： A method is provided for establishing clusters in a distributed data processing environment having a plurality of nodes. The frequency of messages sent for the purpose of cluster formation is selected based on ranking of the nodes. Higher ranking nodes transmit such messages more frequently than lower ranking nodes. Lower ranked nodes thus are provided with an opportunity to join a cluster without first having to transmit their own messages to effectuate the joining.

    摘要： In distributed multinode data processing systems, mechanisms are employed to insure that the nodes are properly informed about the liveness of the other nodes in node groups in the network. In particular, the present invention employs group membership indicia as part of a mechanism for detecting that a node and/or its adapter have failed and have been recently restarted. Having detected this situation, group membership inconsistencies which it can engender are avoided.

    摘要： Liveness determination in a multinode data processing system is enhanced through the use of a shared nonvolatile memory, typically a disk, which is utilized in conjunction with defined transmission protocols to provide an independent communication path usable for both the transmission of node liveness information and for other, more general, data transfer purposes. This path is considered as having the same degree of importance as other network paths and liveness indications from the shared memory path are likewise considered at the same time as liveness indications from another path or paths.

    摘要翻译： 通过使用共享的非易失性存储器（通常为磁盘）来增强多节点数据处理系统中的生命力确定，所述非易失性存储器通常与定义的传输协议一起使用，以提供可用于节点活动信息传输和其他用途的独立通信路径 ，更一般，数据传输的目的。 该路径被认为具有与其他网络路径相同程度的重要性，并且来自共享存储器路径的活动性指示同时被考虑在来自另一路径或路径的活动指示的同时。
