摘要： A system and method is disclosed that allows resources to be shared among multiple entities, but which can appropriately release system resources after the failure or shutdown of the calling entity. In one approach, a monitoring entity is available to check for session failures. If a session failure is detected, the session is identified in a shared list that is accessible to other related entities. The related entities can be configured to piggyback a message to an appropriate node to kill, shutdown, or release resources associated with the failed session. Alternatively, a related entity can be specifically initiated to send a message to the appropriate node to kill, shutdown, or release the resources.

摘要： A method and mechanism for implementing pipelined prefetching in a computer system is disclosed. Data prefetching is utilized to predictably retrieve information between multiple levels of nodes in the computer system, in which a first server may receive prefetched data from a second server, the second server receives prefetched data from a third server, with the chain of prefetching extending as long as needed/desired to effect efficient data transfers between the nodes.

摘要： A method and mechanism for dynamically changing the logical path of a state machine to avoid conflicts or problems is provided. A toggle state is employed for a state machine that allows dynamic changes in the computation path of a state machine. By analyzing the expected response state of a remote state machine, toggle states can be inserted in the path of a local state machine to avoid conflicts. This approach can be advantageously employed to reduce or prevent half-duplex violations for communications between applications on multiple computing nodes.

摘要： A method and apparatus for efficiently processing data requests in a network oriented n-tier database environment is presented. According to one embodiment of the invention, certain or all data from the tables of a database server device can be maintained in tables on the client device in a client side database cache server system. This local cache allows the network oriented n-tier database system to eliminate the expense of repetitive network transmissions to respond to duplicate queries for the same information. Additionally, the local client device may also keep track of what data is cached on peer network nodes. This allows the client to request that data from a peer database cache server and off load that burden from the database server device. Moreover, the local client may also keep statistics regarding the frequency of requested data in order to optimize the data set maintained in the local database cache server.
