摘要： Approaches are used for efficiently and effectively managing the dynamic allocation of resources of multi-node database systems between services provided by the multi-node database server. A service is a category of work that is hosted on the database server. The approaches manage allocation of resources at different levels. For services that use a particular database, the performance realized by the services is monitored. Resources assigned to the database are allocated between these services to ensure performance goals for each are met. Resources assigned to a cluster of nodes are allocated between the databases to ensure that performance goals for all the services that use the databases are met. Resources assigned to a farm of clusters are assigned amongst clusters based on service level agreements and back-end policies. The approach uses a hierarchy of directors to manage resources at the different levels.

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： 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.

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.

摘要： A method for locking resources, including: receiving, by an accelerator, a first request from a first client to lock a first resource; evaluating, by a computer processor of a server, a hash function using an identifier of the first resource as an input to the hash function; identifying, by the computer processor and based on evaluating the hash function, a first hash bucket in a shared memory residing in a physical memory of the server; detecting that the first hash bucket is occupied; and sending the first request to a master lock monitor residing in a user space of the server based at least on detecting that the first hash bucket is occupied.

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： A V-twin engine having a crankcase and a pair of cylinders defining a V-space therebetween, wherein the V-space is substantially enclosed, and a carburetor is positioned within the V-space. An intake air preheating arrangement supplies heated intake air to the carburetor, and a carburetor heating arrangement heats the V-space and the carburetor which is positioned within the V-space. Each of the foregoing arrangements, used separately or in combination within one another, aids in preventing “freeze-up” of the carburetor during running of the engine in a cold environment.
