Abstract: An apparatus, program product and method utilize hidden group membership to facilitate the processing of originator requests to a group in a clustered computer system. With hidden group membership, a requesting originator is temporarily joined to a group in such a manner that the originator is both hidden and provided with limited access rights, e.g., so that some of the messages sent by the members of a group when processing the request are neither sent to nor received by the originator.

Abstract: Members of a primary-backup group in a clustered computer system are organized into subgroups to manage primary and backup resources being managed by the group. Group members are placed into subgroups based upon their access to particular resources, such that a primary subgroup may be defined comprised of members having access to a common primary resource, with one or more backup subgroups defined comprised of members having access to a common backup resource. A join protocol is used to determine to which of a plurality of resources managed by the primary-backup group a joining member has access, and to add the joining member to a subgroup for a resource to which the joining member has access.

Abstract: An apparatus, program product and method utilize subgroup-specific leader members to exchange group data between group members during the handling of a request to organize members into a group in a clustered computer system, e.g., when handling a membership change operation such as a merge or join. Such subgroup leaders may be determined locally within individual subgroup members, and moreover, the subgroup members may locally track the transmission status of group data for the various subgroups. Each subgroup includes one or more members that are known to store group data that is coherent among all subgroup members.

Abstract: An apparatus, program product and method support the dynamic modification of cluster communication parameters such as a fragmentation size parameter through controllably deferring the processing of a requested fragmentation size change in a source node until after receipt an acknowledgment message for at least one unacknowledged message sent by the source node to a plurality of target nodes. By controllably deferring such processing until it is confirmed that any such previously-unacknowledged messages sent by a source node have been received by any target nodes, synchronization between the source node and the target nodes may be obtained, and a fragmentation size change may occur in a coordinated fashion such that future messages from the source node to the target node will be processed by both the source and the target nodes using the modified fragmentation size parameter.

Abstract: A computing node that functions as a member within a computing system group, such as a cluster, that has a status allowing receipt of group messages even though the node is not an active member of the cluster. The node is able to function as a primary member or as a backup member that controls redundant resources to be utilized in case of a failure. The computing node is able to have one of two status values, an “Active” status and an “Ineligible” status. Members that are able to function as a primary member have an “Active” status assigned, and a member that is not configured or otherwise eligible to perform as a primary member is assigned an “Ineligible” status. Members with an Ineligible status receive all group messages and therefore are able to become configured and eligible to become a primary member.

Abstract translation: 作为计算系统组（例如集群）中的成员的计算节点，其具有允许接收组消息的状态，即使节点不是集群的活动成员。 节点能够充当主要成员或作为备份成员，控制在发生故障时使用的冗余资源。 计算节点能够具有两种状态值之一，即“活动”状态和“不合格”状态。 能够作为主要成员的成员具有分配的“活动”状态，未配置或以其他方式作为主要成员执行的成员被分配“不合格”状态。 具有不合格状态的成员接收所有组消息，因此能够被配置并有资格成为主要成员。

Abstract: An apparatus, program product and method utilize ordered messages in a clustered computer system to defer the execution of a merge protocol in a cluster group until all pending protocols in each partition of a group are handled, typically by ensuring either cancellation or completion of each pending protocol prior to execution of the merge protocol. From the perspective of each group member, the execution of the merge protocol is deferred by inhibiting processing of the merge request by such member until after processing of all earlier-received pending requests has been completed.

Abstract: An apparatus, program product and method support the dynamic modification of cluster communication parameters through a distributed protocol whereby individual nodes locally confirm initiation and status information for every node participating in a parameter modification operation. By doing so, individual nodes are also able to locally determine the need to undo locally-performed parameter modifications should any other node be incapable of performing a parameter modification. Moreover, specifically with respect to cluster communication parameters such as heartbeat parameters, such parameters may be dynamically modified by configuring a sending node to send a heartbeat message to a receiving node, with the heartbeat message indicating that a heartbeat parameter is to be modified. In response to the heartbeat message, the receiving node may then send an acknowledgment message to the sending node that indicates whether the heartbeat parameter has been modified in the receiving node. Further, modification of the heartbeat parameter in the sending node may be deferred until the acknowledgment message from the receiving node indicates that the heartbeat parameter has been modified in the receiving node.

Abstract translation: 装置，程序产品和方法通过分布式协议支持集群通信参数的动态修改，从而各个节点本地确认参与参数修改操作的每个节点的启动和状态信息。 通过这样做，如果任何其他节点不能执行参数修改，则各个节点还能够本地地确定需要撤销本地执行的参数修改。 此外，具体地，关于诸如心跳参数的集群通信参数，可以通过配置发送节点向接收节点发送心跳消息来动态地修改这些参数，其中心跳消息指示心跳参数将被修改。 响应于心跳消息，接收节点可以然后向发送节点发送指示接收节点中是否已经修改了心跳参数的确认消息。 此外，可以延迟发送节点中的心跳参数的修改，直到来自接收节点的确认消息指示在接收节点中已经修改了心跳参数。
