Abstract: Method, apparatus and program product are provided for rebuilding faulty metadata in a storage controller coupled to a host device. Faulty metadata may include metadata which no longer matches the associated customer data tracks stored on a DASD or other storage device. When an error in metadata is describing a first customer track is detected, a range of other customer tracks in which the error is also likely to have occurred is identified. The metadata tracks associated with the first customer track and the other customer tracks are selected to be invalidated. A command is received through a host interface, and the specified metadata tracks are invalidated while the controller remains on-line with the host and continues to process other host I/O operations. Subsequently, the invalidated metadata tracks are rebuilt. The disclosed method, apparatus and program product invalidate the faulty metadata with reduced impact on normal host/controller I/O operations.

Abstract: A method (and system) for coding a signal includes comparing a first prediction which is based upon a previously reconstructed signal to an actual signal to determine a first prediction error, comparing a second prediction which is based upon temporal filtering to the actual signal to determine a second prediction error, and selecting one of the first prediction error and the second prediction error.

In one embodiment, the processor is configured for executing application software for integrating the audio data into the on-board diagnostic system. The recording system further includes time stamping circuitry operably connected to the recording device module for associating a time code with the undetected signals for generating a time-stamped electrical data signals.

Abstract: A method, computer program product and computing device for promoting reuse of previously generated access plans are disclosed. SQL statements containing literals are amended so as to substitute a parameter marker for each literal. Amended statements are provided to the DBMS along with parameters including the substituted literals and a substitution indicator indicating that the substitution has been performed. The DBMS assesses the soundness of the substitutions that are performed. Soundness may be measured in terms of the semantic correctness of the amended statement and the likelihood that the literal substitution will improve DBMS efficiency. If a substitution is unsound, the DBMS may obtain and optimize the original version of the amended SQL statement. Otherwise, the amended statement is optimized. Advantageously, SQL statements originally differing only in the value of one or more literals may become functionally equivalent, and the reuse of cached, previously generated access plans is thus promoted.

Abstract: A method for document annotation includes providing a contextual framework extending over multiple electronic documents. Annotations are input to a computer by a user with respect to two or more of the documents, while the user views the documents on a computer screen. Each of the annotations is stored together with respective context information in a memory of the computer, the context information including multiple fields defined by the framework. The annotations are sorted with respect to the two or more documents according to one or more of the multiple fields of the respective context information, and the sorted annotations are output for viewing by the user.

Abstract: An apparatus, program product and method in which a memory address space is allocated non-uniformly to IO resources in a memory mapped IO fabric based upon the locations of individual IO endpoints to which such IO resources are coupled. In a PCI-based environment, for example, PCI adapters are allocated memory address ranges in a PCI bus address space based upon the locations of the particular slots within which the PCI adapters are mounted.

Abstract: A method is described for performing model-based optical proximity corrections on a mask layout used in an optical lithography process having a plurality of mask shapes. Model-based optical proximity correction is performed by computing the image intensity on selected evaluation points on the mask layout. The image intensity to be computed includes optical flare and stray light effects due to the interactions between the shapes on the mask layout. The computation of the image intensity involves sub-dividing the mask layout into a plurality of regions, each region at an increasing distance from the evaluation point. The contributions of the optical flare and stray light effects due to mask shapes in each of the regions are then determined. Finally, all the contributions thus obtained are combined to obtain the final computation of the image intensity at the selected point.

Abstract: Methods, systems, and media to automatically deploy an, e.g., a JS2EE file between environments are disclosed. Embodiments include hardware and/or software for selecting one or more applications in an original system for export. The applications along with their corresponding application data, configuration data, and descriptor files, are compressed into one or more archive files such as Enterprise Archives (EARs). Variable configuration data associated with the target environment is identified so the values of the variable configuration data can be adapted for the target environment. Then, the target environment is adapted for installation of the application and the application is installed in the target environment. Advantageously, this deployment of the application may reduce the chance of user error, require less J2EE knowledge and script maintenance, and complete faster than deployments effected manually.

Abstract: A method for sequencing delivery of information packets from a router having several processing elements to a receiving processing installation, wherein delivery of the packets must be completed in the order the packets arrive at the router. A linked list of packets is formed in the order they are received at the router, and each packet fragmented into successive fragments. Each fragment is processed at the router. The last fragment of each packet in each linked list is labeled with the sequence in which the packet was received, and enqueued in the order labeled for each last fragment on each linked list. Each fragment of each packet is delivered as processed, except the last fragment of each packet on its linked list to the receiving processor installation, and thereafter, transmitting the final fragment of each packet after processing only if that fragment is at the head of the queue.

Abstract: A method for enhancing the privacy of recipients of personalizing text messages such as advertisements delivered to communication terminals such as cellular telephones. A common carrier such as a cellular telephone service provider gathers personal information from a subscriber at the time the subscriber signs on for service and receives a communication terminal. The carrier loads the terminal with a table that assigns variables to elements of personal information. The carrier accepts messages such as advertisements for distribution to subscribers. These messages use the variables that the carrier has loaded into the subscribers' terminals. When such a message is received, a subscriber's terminal replaces the variables with the elements of personal information by referring to the table.

One embodiment provides a computer-implemented method of processing queries requesting data accessed using a data definition framework in a computerized environment. The method includes receiving a query from a requesting entity, wherein the query is configured to access data via a data definition framework referenced in the query and determining whether the data definition framework is current. If the data definition framework referenced in the query is not current and has been replaced by a different data definition framework then the query may be run against the data using the data definition framework referenced in the query and the requesting entity may be notified of the different data definition framework. Alternatively, the requesting entity may be notified of the different data definition framework without running the query.
