Abstract: A method, system, and computer program product for enabling efficient start up of an application server with the components required for complete operation of the supported application. A pre-processor autonomically determines the specific services that are required by the application to be initiated within the application server during start up of the application. The specific services are selected from a comprehensive list of available services for start up of the application server. The application server is then started up with only the specific services required by the application, rather than the full list of services.

Abstract: 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.

Abstract: 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.

Abstract: A method, apparatus, system, and signal-bearing medium that, in an embodiment, create a tag that identifies an application, store the tag in a class of the application, and count a number of times the tag appears in an entry nearest a top of a runtime stack. Counting the number of times the tag appears may include finding an entry nearest a top of a runtime stack that includes the tag and incrementing a count associated with the tag in response to the finding. The creating is performed in response to submission of the application to an application server. In an embodiment, the tag is created based on a cryptographic hash of an archive file that contains the application. In response to a method associated with the class requesting a remote service, the tag is embedded in a remote service request message, which is sent to a remote application server, where the tag is stored in a service class.

In an embodiment, the second e-mail has an encrypted portion, which includes an identifications of the blind-copy recipient, the sender of the first e-mail, and the other recipients of the first e-mail. The blind-copy recipient of the first e-mail is not identified in the first e-mail to the other recipients of the first e-mail. In this way, blind-copy recipients of e-mails may be notified of further associated e-mails.

Abstract: 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.

Abstract: 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.

Abstract: 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.
