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 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 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.

摘要： Techniques for authenticating users when an operation requested by a user in one of the systems of a distributed system is redirected to another system of the distributed system. The user is authenticated in the usual way to the one system but is authenticated to the other system for the redirected operation by an authentication proxy in the first system. The fact that the authentication proxy is providing a redirected operation means that the user who requested the operation has been authenticated to the one system. The other system is thus able to authenticate the user for the redirected operation with different authentication information than would otherwise be required. An example of how the techniques are used is a distributed database system where one of the database systems in the distributed system is a cache for another of the database systems.

摘要： One embodiment of the present invention provides a system that modifies a function defined within an application programming interface (API) so that the function includes additional code. The system receives an additional code module to be integrated into the function within the API. The system also receives a command to integrate the additional code module into the function. This command is received through a pre-defined function within the API for integrating additional code into functions within the API. In response to the command, the system links the additional code into the function so that the additional code module is executed when the function is called. In one embodiment of the present invention, linking the additional code module into the function involves linking the additional code module as an entry function that is executed at the beginning of the function. In one embodiment of the present invention, linking the additional code module into the function involves linking the additional code module as an exit function that is executed at the end of the function. In one embodiment of the present invention, linking the additional code module into the function involves linking the additional code module as a replacement for original code for the function.
