Abstract: 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.

Abstract: A gossiping scheme for sharing node status in a cluster of nodes provides a robust mechanism for determining node status within the cluster. Nodes transmit gossip messages to each other nodes, the gossip messages listing other nodes in the cluster that are operational. When a node does not receive a gossip message from a particular node within a predetermined time period, then the node transmits messages to the other nodes indicating that the particular node is down. However, if another node has received a packet from the particular node within the predetermined time period and receives the node down message, then the other node responds with a node alive message.

Abstract translation: 用于在节点集群中共享节点状态的八卦方案为确定集群内的节点状态提供了一种可靠的机制。 节点向每个其他节点发送八卦消息，八卦消息列出了群集中其他可操作的节点。 当节点在预定时间段内没有从特定节点接收到八卦消息时，节点向其他节点发送指示特定节点关闭的消息。 然而，如果另一节点在预定时间段内已经从特定节点接收到分组并且接收到节点向下消息，则另一个节点用节点存活消息进行响应。

Abstract: A unique device name is assigned to each of a plurality of shared storage devices in a cluster configuration database defining membership of nodes in a cluster. A particular node among the nodes defined by the cluster configuration database as a member of the cluster searches the cluster configuration database for a device identifier matching a device identifier of a shared storage device hosted by the particular node. In response to finding a matching device identifier in the cluster configuration database, the particular node renames, in a local configuration maintained at the particular node, a storage device associated with the matching device identifier with the unique name assigned to that storage device in the cluster configuration database.

Abstract: The present invention provides a computer implemented method, data processing system, and computer program product to protect a first user from authorization limitation by a second user. The computer may receive an authorization command from the second user, wherein the authorization command targets the first user, and the second user is at least partially authorized to operate the authorization command. The computer determines that the first user is an ancestor user of the second user. In addition, the computer, responsive to a determination that the first user is an ancestor user of the second user, prevents operation of code of the authorization command to change an authorization of the first user.

Abstract: Disclosed is a computer implemented method and computer program product to resume a process at an arrival machine that is in an identical state to a frozen process on a departure machine. The arrival machine receives checkpoint data for the process from the departure machine. The arrival machine creates the process. The arrival machine updates a page table, wherein the page table comprises a segment, page number, and offset corresponding to a page of the process available from a remote paging device, wherein the remote paging device is remote from the arrival machine. The arrival machine resumes the process. The arrival machine generates a page fault for the page, responsive to resuming the process. The arrival machine looks up the page in the page table, responsive to the page fault. The arrival machine determines whether the page is absent in the arrival machine. The arrival machine transmits a page-in request to the departure machine, responsive to a determination that the page is absent. The arrival machine receives the page from the departure machine.

Abstract: A method is disclosed to assign Priority to Processes based on Roles. The method calculates the process priority of the process using a scheduler running in the computer system, based on either a first weight of a first role, a second weight of a second role, or a calculated weight if both the first and second roles can unlock access to the process. The method then assigns a share of the computer system's time to the process, the share of time being based on the process priority calculated for the process.

Abstract: An event notification method 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.

Abstract translation: 用于分布式处理系统的事件通知方法提供与重复事件（例如被复制的特定事件）相关联的队列空间和事件处理带宽的减少，并且导致为多个消费者传播的多个事件通知。 当在事件通知队列的输入处接收到重复的事件通知时，而不是排队重复的事件通知，已经在队列中的事件通知的序列号被更新，以便向事件消费者指出正在有多少重复事件具有 被收到 更新的事件通知的时间戳也可以被设置为最近接收到的重复事件通知的时间戳。

Abstract: In response to a stimulus indicating configuration of a node into a cluster of a plurality of nodes including the node, the node determines whether or not the node has a universally unique identifier (UUID), and if not, the node provides its own persistent self-assigned UUID. The node searches a cluster configuration database for a temporary identifier associated with the node. In response to the node locating the temporary identifier of the node in the cluster configuration database, the node writes its self-assigned UUID into the cluster configuration database and joins the cluster.
