Abstract: Provided are techniques related generally to computer communication and, more specifically, to techniques that provide legacy applications with access to a cluster infrastructure. A pseudo interface layer provides applications with internet protocol (IP) family sockets access to cluster awareness protocols in a manner that may be transparent to both the application and the cluster awareness layer of a kernel.

Abstract: A WPAR is migrated. Responsive to starting a checkpoint process, data and control information is collected and stored for IPC objects in the WPAR. Responsive to receiving a request to restart the WPAR, a type of IPC object is determined. Responsive to a determination that the IPC object is not an IPC shared memory object, a kernel handle that a process wants to be used for a new IPC object is registered. A request to create a new IPC object comprising a name uniquely associated with the IPC object and a WPAR identifier is issued. An entry that matches the name and WPAR identifier is identified and a virtual kernel handle is retrieved. The new IPC object is created. The virtual kernel handle is mapped to a real kernel handle and returned to the process. Data and control information is retrieved and overlaid onto the new IPC object.

Abstract: A speaker assembly mounted on a bracket extending from a ceiling comprises an enclosure that includes a bottom wall, side walls including opposing first and second side walls, a sleeve that receives a tubular member of the bracket, and an interior wall having a first segment that extends from the sleeve to the first side wall and a second segment that extends from the sleeve to the second side wall. The interior wall cooperates with the sleeve to divide the enclosure into two approximately equal sized compartments. Each of the speakers within the assembly either forms, or is mounted in or on, one of the side walls. A top plate is mounted on, and forms a top of, the enclosure and seals the two compartments, the top plate having an opening that is aligned with the sleeve when the top plate is mounted on the enclosure. A power unit and circuitry for the speakers are mounted on the top plate.

Abstract: 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.

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: A computer implemented method, apparatus, and computer program product for a checkpoint process associated with a device driver in a workload partitioned environment. In response to initiation of a checkpoint process, a stream is frozen. The stream comprises a set of kernel modules driving a device. Freezing the stream prevents any module in the set of kernel modules from sending any messages, other than a checkpoint message, to another module in the set of kernel modules. The message block for each module in the set of kernel modules is updated with internal data to form a restart message. The internal data is data describing a state of the module in the set of kernel modules.
