摘要： A database access facility for accessing databases includes a monitoring function which monitors accesses by requesters of database data. The monitoring function tracks which database fields are requested to dynamically determine the fields which the application needs. Once sufficient tracking data is obtained, subsequent accesses to the database on behalf of an application are automatically modified by the application server to request only the fields which are likely to be needed. Preferably, the database access facility is an application server for one or middle tier applications which access the database on behalf of multiple clients in a three-tier client-server environment.

摘要： A method, apparatus, system, and signal-bearing medium that, in an embodiment, send units of work to grid executors, create training data based on the performance of the grid executors, and train a neural network via the training data. The training data includes pairs of input and output data, where the input data is the types of the units of work and the output data is the service strengths of the grid executors. Once the neural network has been trained, subsequent units of work have their grid executors selected by inputting the types of the units of work to the neural network and receiving a service strength from the neural network as output. The grid executors are then selected based on the output service strength from the neural network. In this way, in an embodiment, the grid performance may be increased.

摘要： Disclosed is an apparatus, method, service product, and program product which each provide an enhanced, registration-based event handler mechanism. Listener programs are located and compiled before notification is needed. When notification is ultimately required, the pre-located listeners can be called directly without incurring the performance expense associated with first locating and then calling each listener.

摘要： An apparatus and method provide client-side routing of database requests to enhance the performance of a partitioned database system. In a first embodiment, the database client determines the correct database server for a transaction, and routes requests for the transaction to the correct database server. In a second embodiment, the database client sends a first database request in a transaction to a selected database server, determines from the response the correct database server, and routes all subsequent requests for the transaction to the correct database server. In a third embodiment, the database client sends a first database request in a transaction to a selected database server, which routes the first request to the correct database server, which returns the results directly to the database client via direct connection. The database client then routes all subsequent database requests in the transaction directly to the correct database server.

摘要： A method, apparatus, system, and signal-bearing medium that, in an embodiment, determine a cipher strength based on a trust level associated with a request, create a unit of work based on the request, encrypt the unit of work into a message based on the cipher strength, and send the message to grid servers. In various embodiments, the trust level may be determined based on a security token associated with the request or based on a zone from which the request originates. In various embodiments, the request originates from a client that belongs to the zone or originates from one of the grid servers that belongs to the zone. In an embodiment, a request from a grid server may be associated with a response to a previous unit of work that the grid server executed.

摘要： In an embodiment, a request is received that is directed to a page. A determination is made whether a session associated with the request already exists by determining whether the request is dependent on a previous request. If the session does not already exist, then a decision is made whether the request will result in creating a session. If the request will result in creation of a session, then a server is selected based on a load-balancing metric instance associated with the page, and the request is sent to the selected server. The load-balancing metric instance has an algorithm and an input parameter to the algorithm. The server is selected by executing the algorithm and selecting the server identified by an output parameter from the algorithm.

摘要： A method, apparatus, system, and signal-bearing medium that, in an embodiment, determine units of work in a page, join selected pairs of the units of work with lowest complexity metrics until all of the units of work have complexity metrics that are less than a threshold. The joining is subject to rules of a dependency graph, which indicates data dependency relationships of the units of work. The selected joined pairs are then encapsulated into a processing unit, which is sent to multiple grid servers. Responses from the grid servers are used to assemble dynamic content into the page. In an embodiment, the complexity metrics are then modified based on an exponential moving average of responses times of the units of work. In this way, in an embodiment, the performance of assembling the page may be increased.

摘要： A method, apparatus, system, and signal-bearing medium that, in an embodiment, calculate the average number of servers that executed an application in a previous time period, decide whether the current number of servers that execute the application is less than the average number of servers, and, if so, power on the average number of servers. The application is then distributed across the average number of servers. In an embodiment, the server is powered on by increasing the clock speed of the processors associated with the servers. In an embodiment, a determination is periodically made whether the response time of the application is greater than a threshold, and, if so, the servers are powered on and the application is distributed across the servers. In an embodiment, a determination is periodically made whether the response time of the application is less than a threshold, and, if so, servers are powered off and the application is distributed across the remaining servers.
