摘要： A composite resource is established that includes a plurality of members. Each of the members is capable of providing a comparable service. A coordinator monitors a state of each member of the composite resource. A component requests the service from the coordinator. The coordinator arranges for the service to be provided to the component by a particular member of the composite resource. When the particular member ceases to be active, the service is automatically provided to the component by another member in the composite resource. A state of the composite resource is maintained independently of the state of each member in the composite resource.

摘要： Events of interest are detected in order to manage a high availability framework. In a framework in which a plurality of components are executing, the components are periodically polled to detect occurrence of the event of interest. A monitor is also established for one or more of the components. After the first component causes the event of interest to occur, the monitor communicating the event of interest to the framework without waiting for the framework to poll the first component.

摘要： A cluster management system dynamically assigns a category to a server node based on the server node's attributes. The system can detect a change in value of a server attribute of a first server node. Then, in response to detecting the change in value of the server attribute, the system identifies a plurality of server attributes for the first server node, and dynamically assigns to the first server node a category that matches the server attributes. Further, the system can add the server node to a server pool that has a matching category with the server node.

摘要： A method and computer-readable storage representing resources in a cluster by a plurality of attribute-value pairs that together are part of a “resource profile,” in which each attribute-value pair defines all, or a portion of, a management policy that applies to the resource. A clusterware manager configures a resource according to the resource profile, and follows a resource profile syntax that specifies a runtime value for the resource in which an actual value is substituted at runtime.

摘要： Techniques are provided for managing caches in a system with multiple caches that may contain different copies of the same data item. Specifically, techniques are provided for coordinating the write-to-disk operations performed on such data items to ensure that older versions of the data item are not written over newer versions, and to reduce the amount of processing required to recover after a failure. Various approaches are provided in which a master is used to coordinate with the multiple caches to cause a data item to be written to persistent storage. Techniques are also provided for transferring data items and locks associated with the data items from one node to another.

Specifically, techniques are provided for coordinating the write-to-disk operations performed on such data items to ensure that older versions of the data item are not written over newer versions, and to reduce the amount of processing required to recover after a failure. Various approaches are provided in which a master is used to coordinate with the multiple caches to cause a data item to be written to persistent storage. Techniques are also provided for managing checkpoints associated with the caches, where the checkpoints are used to determine the position at which to begin processing recovery logs in the event of a failure.

摘要： A method for monitoring and maintaining a pipeline is shown which includes installing a monitoring system for measuring at least one parameter of interest, the monitoring system including various monitoring sensors placed at selected locations along the pipeline. A series of measurements are taken using the monitoring sensors in real time. The measurements are analyzed to identify anomalous conditions existing in the pipeline being monitored. An autoadaptive corrective action is implemented based upon the real time measurement of the parameter of interest.
