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.

摘要： A method and apparatus are provided for performing an array DML operation. During the performance of the operation on a data item in the array, and if an error occurs, then error information is stored and the array operation continues by performing the operation on the next data item in the array. The error is used to create update input data for the DML operation, and the update input data can be supplied during run-time of the program.

摘要： A method and apparatus for is provided for efficiently transmitting multiple rows of data to a client station. The client station generates a query that is transmitted to a remotely located server, which in turn generates a query result. The server transmits the first row of data from the query result to the client. The remaining rows of data are transmitted by first calculating the difference between successive rows of data. Next, the server sends only the unique rows resulting from the calculated row difference to the client. The server also send an indication of the number of non-repeated value columns detected in order to allow reconstruction of the query result by the client station.

摘要： A method and apparatus allows clients to share ports on a server. The server can maintain more sessions than server ports. When a client sends a command directed to the server, a resource manager inserted between the clients and the server intercepts the command and directs the server to select the session associated with a client prior to or at the same time that the resource manager forwards the intercepted command to the server. Responses from the server are forwarded by the resource manager to the client that sent the command to which the response relates. The resource manager may be coupled to multiple clients, and one or more ports of one or more servers.

摘要： In transferring data from/to a database server, the size of a network buffer used by a network layer is dynamically adjusted according to the call type and expected size of data to be transferred for the call. Due to such use of appropriate buffer size, throughput performance of the transfer may be enhanced.

摘要： Direct memory accessed is used to perform database operations between two or more machines. A first segment of memory is allocated for a second machine, where at least one of the first machine and second machine is a database server. During performance of a database operation that involves the transfer of data from the second machine to the first machine, data in the first segment of memory is buffered in response to the second machine writing the data to a second segment of memory on the second machine.

摘要： One embodiment of the present invention provides a system that facilitates secure messaging. The system starts by creating a message at an origin. Next, the system computes a digest of the message. This digest is signed using an origin private encryption key. The message and the signed digest are forwarded to a queue for delivery to a recipient. Upon receiving the message and the signed digest at the queue, the system verifies that the digest was signed at the origin by using an origin public encryption key. If the signature is valid, the origin cannot deny creating the message. Valid messages and digests are placed on the queue and the recipient is notified that the message is available.

摘要： A computing device displays a call history graphical user interface (GUI). The call history GUI includes a new list and an old list. The new list may include new missed call elements and missed call elements associated with new unopened voicemails. The old list may include other call history GUI elements, such as old missed call elements and missed call elements associated with opened voicemails.

摘要： A method and apparatus allows a client or other device separate from a server to retrieve from the server more data than is requested by an application program on the client. The additional data is maintained by the client or other device and provided to the application program in response to a subsequent request, reducing the number of times data is requested from the server, and also the processing and overhead required by the server to supply the data. If the server releases memory pointing to the data on the server at the time or after all data specified by the application program has been retrieved, because the data is potentially retrieved from the server in amounts larger than requested by the application program, the server may release memory pointing to the data on the server sooner than it would by processing requests for the data from the application program alone.
