Abstract: A data processing system allows processes to be checkpointed and restarted. The system saves the old process and thread identifications in a process table. When an application makes a system cell passing the old process and/or thread identifications as parameters, the system performs a mapping algorithm to supply the system call with the new process and/or thread identifications. When a system call returns a new identification, the system performs a remapping algorithm to return the old identifications to the calling application program. When a group of process is restarted for which the process group leader was not checkpointed, the system creates a ghost process group leader.

Abstract: A method, apparatus, and computer instructions for handling requests in a data processing system. A plurality of processes is provided to handle the requests. Each of the plurality of processes is assigned to handle requests from a subset of foreign ports within a plurality of foreign ports such that a set of foreign ports assigned to a process is unique with respect to other subsets of foreign ports within the plurality of foreign ports. A foreign port is identified in a request in response to receiving the request. The request is sent to a process assigned the subset of foreign ports having a match to the foreign port in the request, wherein the process handles the request.

Abstract: Computer implemented method, system and computer usable program code for routing messages in a message stream. A computer implemented method for routing messages in a message stream includes receiving a specification of desired messages, the specification containing a payload and receiving at least one message, the message containing a payload.

Abstract: Method, system and computer program product for determining the targets of branches in a data processing system. A method for determining the target of a branch in a data processing system includes performing at least one pre-calculation relating to determining the target of the branch prior to writing the branch into a Level 1 (L1) cache to provide a pre-decoded branch, and then writing the pre-decoded branch into the L1 cache. By pre-calculating matters relating to the targets of branches before the branches are written into the L1 cache, for example, by re-encoding relative branches as absolute branches, a reduction in branch redirect delay can be achieved, thus providing a substantial improvement in overall processor performance.

Abstract: An improved method, apparatus, and computer instructions for a mobile device for managing ring tones. A radio frequency transmission is detected from another mobile device. In response to detecting the radio frequency transmission from the other mobile device, a ring tone used by the other mobile device is identified to form an identified ring tone. The current ring tone is selectively changed for the mobile device to an alternate ring tone, depending on the identified ring tone.

Abstract: The server side Transfer Control Protocol is modified so that the server returns a SYNACK message with the window size equal to zero if the server is busy. When a client sends a TCP connection request and receives a synchronization acknowledgement message with the window size equal to zero, the client knows that the server received the connection request and that the server is busy. The client may then send an acknowledgement message to complete the three-way synchronization handshake, thus successfully completing the connection. Thereafter, the client side TCP may probe the server side TCP until a window update message is received from the server. When the server sends a window update message to set the window size to a non-zero size, the client knows that the server is no longer busy and the client application may then use the TCP connection.

Abstract: A method and system for embedding prefetch tags in the HTML of a user-requested webpage so that, after delivery of the user-requested webpage to the user, the proxy can cache webpages that the user is likely to request. After the browser issues a request for a webpage to the proxy, the proxy passes the request to the web server. The web server obtains the webpage and embeds prefetch tags into the HTML of the webpage. The selection of prefetch tags is determined by a personalization database or log/statistics database in the web server. The web server sends the user-requested webpage back to the user through the proxy. The proxy reads the prefetch tags and prefetches the webpages identified in the prefetch tags. The webpages identified in the prefetch tags are stored in the proxy cache memory so that they can be quickly sent to the user upon request.

Abstract: A computer-implemented method, apparatus, and computer usable program code are disclosed for migrating a virtual adapter from a source physical adapter to a destination physical adapter in a data processing system where multiple host computer systems share multiple adapters and communicate with those adapters through a PCI switched-fabric bus. The virtual adapter is first caused to stop processing transactions. All in-flight transactions that are associated with the virtual adapter are then captured. The configuration information that defines the virtual adapter is moved from the source physical adapter to the destination physical adapter. The in-flight transactions are then restored to their original locations on the destination virtual adapter. The virtual adapter is then restarted on the destination physical adapter such that the virtual adapter begins processing transactions.

Abstract: A method, apparatus, and computer instructions for identifying unsafe synthetic transactions and modifying parameters for automated playback. Bytecode instrumentation is used to dynamically observe the behavior of application code directly and identify each universal resource locator traversed and parameters passed in a transaction. The bytecode instrumentation may determine, based on the parameters passed, that a parameter in the current transaction is an unsafe parameter, and that the unsafe parameter is associated with a test parameter in a previously overridden transaction. If the unsafe parameter has an associated test parameter, the bytecode instrumentation may dynamically override the unsafe parameter in the current transaction with the test parameter in order to make the transaction safe for synthetic playback.

Abstract: A circular VTOL aircraft with a central vertically mounted turboprop engine 14, driving contra-rotating co-axial propellers 24, above a central jet engine (or engines) 12, horizontally mounted on a turntable pod 11 which is steerable through 360 degrees. The turboprop provides vertical thrust from contra-rotating propellers compressing air from an upper circular intake 5 downward through a circular shaped rotor-chamber 6 to a circular vent 10 at the base of the craft. The resulting column of compressed air supports the craft during take-off and landing operations and provides a cushion of air in normal flight. The horizontally mounted jet turbine provides main thrust for horizontal flight and vectored thrust for VTOL. The passenger cabin 21 is circular and is situated in the main body of the disc-shaped craft. Fuel tanks are situated around the circumference of the craft to maximise fuel capacity. The flight-deck 2 is situated at the top centre of the craft, above the engine unit 15, which is detachable.

Abstract: A method, apparatus, and computer instructions for processing a set of links in a document. In response to receiving the document, the set of links in the document is displayed as being validated. The set of links are then processed to determine whether the links are valid or invalid. Whenever one of the links in the set of links is identified as being valid, the display of the link is changed to indicate that the link is valid. Whenever a link in the set of links is identified as being invalid, the display of that link is changed to indicate that this link is invalid.

Abstract: A routing routine is used within a security access program in order to provide access to various heterogeneous directories and registries. Each user logs on with an indication of the domain of which they are a part. An access protocol for the given domain is loaded and used to authenticate the user's access rights.

Abstract: A method, apparatus, and computer instructions for handling instant messages. In response to receiving an instant message, a determination is made as to whether a picture of a sender of the instant message is associated with the instant message, wherein the picture is located in a preexisting database of pictures. The picture with the message is displayed on a display in the data processing system, if the picture is associated with the message.

Abstract: A method for monitoring a data processing system is proposed. The method involves the measuring of state parameters of the system. Indicators of the performance of the system are then inferred from the state parameters by applying fuzzy-logic rules. The proposed solution is based on the idea of estimating the expected value of each performance indicator in the future from a set of corresponding samples. In this way, it is possible to predict the evolution of the system and then detect any problem in advance.

Abstract: A method, apparatus, and computer program product are described for asserting physical presence in a trusted computing environment included within a data processing system. The trusted computing environment includes a trusted platform module (TPM). The data processing system is coupled to a hardware management console. The trusted platform module determines whether the hardware management console is a trusted entity. The trusted platform module also determines whether the hardware management console has knowledge of a secret key that is possessed by the TPM. If the TPM determines that the hardware management console is a trusted entity and has knowledge of the secret key, the TPM determines that physical presence has been asserted.

Abstract: A system and method for path saturation in a storage area network so that the throughput of the storage area network may be determined. The system and method includes a software utility suite that uses either a system administration scripting language, e.g., Perl or Korn shell, or by compiled or machine language software. The software utility suite includes a set of software tools to be installed on one or more computer systems sharing access to a data storage system, such as a storage area network (SAN). The software tools running on these separate computer systems communicate and collaborate in a peer-to-peer fashion in order to coordinate loading, testing and measurement of storage throughput on the shared data storage system. The software tools further coordinate the collection, storage and presentation of results data obtained through such loading, testing and measurement of the storage throughput of the shared data storage system.

Abstract: A method, apparatus, and computer instructions for filtering and prioritizing instant messaging threaded conversations in an instant messaging system based on thread content. The instant messaging client analyzes an incoming message to determine the thread subject. Based on the thread subject analysis, the client determines the priority level associated with the incoming message. The message is then delivered and displayed to the recipient according to the priority level. The present invention also allows a participant initiating a thread of conversation to override filter settings on a messaging client. The authority to override settings may be predicated on an external list, such as a corporate telephone directory. As a result, the participant, having some authority or rights to override the recipient's instant messaging settings, may be allowed to conduct a messaging session with the recipient.
