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： 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： The Authorized Authorization Set System comprising a modified operating system, a command table containing authorized authorization sets, and a modified RBAC security system, eliminates the need for inherited privileges that must be passed to subcommands in order for the command to run. The modified operating system accesses a table containing authorized authorization sets which identify the privileges for all subcommands within a command. When a user is assigned an accessauth for a command, and a sub-command is a privileged sub-command, the privileged sub-command is only run when the accessauth of the sub-command is included in the authorized authorization set of the command.

摘要： System Services to be protected, and corresponding user defined Policies are provided in a table. A module is provided in the operating system with instructions to intercept messages requesting use of System Services, correlate parameters from the messages with the table, and issue an error message signifying denial to a requesting entity if the parameters do not match an entry in the table. If the parameters match an entry in the table, the module generates, and issues a message, to the requesting entity, allowing access to the requested System Service. Optionally, the event may be logged in a memory, and the administrator is notified.
摘要翻译：要保护的系统服务以及相应的用户定义的策略在表中提供。在操作系统中提供了用于拦截请求使用系统服务的消息的指令的模块，将来自消息的参数与表相关联，并且如果参数与表中的条目不匹配，则向请求实体发出表示拒绝的错误消息。如果参数与表中的条目匹配，则该模块生成并发出消息给请求实体，允许访问所请求的系统服务。可选地，事件可以被记录在存储器中，并且通知管理员。

摘要： 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.
摘要翻译：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。

摘要： A system, method, and program product is provided that allows new privileges to be dynamically added to an operating system. Entities are assigned roles and these roles are associated with various authorizations. Authorizations are associated with privileges, including the new privilege. A request is received to dynamically add the new privilege to the operating system. The operating system then dynamically adds the new privilege to the system. A software service is installed that requires the new privilege. A request to execute the installed software service is received from an entity that is running on the operating system. The operating system allows the entity to execute the installed software service in response to determining that the entity has been granted the privilege. However, if the entity has not been granted the new privilege, then the operating system inhibits execution of the software service by the entity.
