摘要： An event notification system for distributed processing systems provides for replacement of event identifiers associated with transient objects, such as processes within the processing system. An event management interface receives a notification from an event producer that an identifier of an event produced by the event producer is no longer valid. The event management interface blocks event notification for the event and dissociates an event registration entry associated with the event from the event identifier. A new event identifier is received from the event producer by the event management interface, which associates the registration entry with the new event identifier. Event notification for the event is then resumed.

摘要： Communication ability between nodes in a cluster-based computer system is tracked to inform applications executing on the nodes of the existence and quality of the endpoint-to-endpoint communications available between the nodes. Communications between a node and other nodes are tracked, and a database records the communication ability between the node and the other nodes for each link between the nodes. The tracking and recording are repeated at the other nodes. A registration by an application executing at a particular one of the nodes to receive notifications of changes in the communication ability with another node over a particular link (or in general) will cause notification of the application when the link status changes.

摘要： A second node receives a message from a first node in a cluster environment. The message includes a unique identifier of a shared data storage device including a cluster configuration database that defines membership of nodes in a cluster. In response to receiving the message, the second node attempts to find the shared data storage device. In response to finding the shared data storage device, the second node locates and reads the cluster configuration database on the shared data storage device. The second node then assimilates a cluster configuration update indicated by the cluster configuration database.

摘要： An event notification system for distributed processing systems provides remote and local node event notification in systems that require local registration of an event consumer in order produce an event notifications. To provide notification of an event occurring on a remote node, either event consumers on all nodes in the cluster register locally to receive event notifications and specify that the event is a cluster event, in which case the nodes send notification of their locally-occurring events to all nodes, or remote registrations are accepted at nodes and if a local consumer for the event is not present, a listener thread registers as an event consumer. The listener thread sends the event notifications to the remote nodes registered as consumers for the event by observing communication between the event producer and the local consumer, or receiving the event notifications directly if there is no local consumer.

摘要： A scheme for monitoring node operational status according to communications transmits messages periodically according to a heartbeat rate among the nodes. The messages may be gossip messages containing the status of the other nodes in the pairs, are received at the nodes and indications of the communications delays of the received messages are stored, which are used to compute statistics of the stored communications delays. Parameters of the node status monitoring, which are used for determining operational status of the nodes, are adjusted according to the statistics, which may include adjusting the heartbeat rate, the maximum wait time before a message is considered missed, and/or the maximum number of missed messages, e.g., the sequence number deviation, before the node is considered non-operational (down).

摘要： Communication between clusters of processing nodes is initiated by designating a link layer address and a target node name in a remote cluster. The link layer address is transmitted to the target node via a regular network transmission. The link layer address is stored locally in each cluster and the nodes in each cluster are signaled that a configuration change has been made, so that gateway nodes in the clusters can obtain the link layer address to use for subsequent communications with the other cluster, such as event notifications of node status changes.

摘要： An event notification system for distributed processing systems provides reduction of queue space and event processing bandwidth associated with duplicate events such as a particular event that is duplicated and results in multiple event notifications propagated for multiple consumers. When a duplicate event notification is received at an input to an event notification queue, rather than queuing the duplicate event notification, a sequence number of the event notification already in the queue is updated to indicate to the event consumer, exactly how many duplicate events have been received. The timestamp of the updated event notification may also be set to the timestamp of the most recently received duplicate event notification.
