Abstract: A new search algorithm for optimal topology construction which utilizes a sequence of transpositions of the topology adjacency matrix index. Preferably, the search involves: evaluating an objective function for each transposition of the current index permutation state; selecting the transposition corresponding to the gradient of the objective function at convex regions of the permutation space; and allowing the transposition search to follow a positive gradient within an window length equal to the maximum distances between local edge objective minima.

Abstract: Unlike traditional clustering methods that focus on grouping objects with similar values on a set of dimensions, clustering by pattern similarity finds objects that exhibit a coherent pattern of rise and fall in subspaces. Pattern-based clustering extends the concept of traditional clustering and benefits a wide range of applications, including e-Commerce target marketing, bioinformatics (large scale scientific data analysis), and automatic computing (web usage analysis), etc. However, state-of-the-art pattern-based clustering methods (e.g., the pCluster algorithm) can only handle datasets of thousands of records, which makes them inappropriate for many real-life applications. Furthermore, besides the huge data volume, many data sets are also characterized by their sequentiality, for instance, customer purchase records and network event logs are usually modeled as data sequences.

Abstract: A general framework for mining concept-drifting data streams using weighted ensemble classifiers. An ensemble of classification models, such as C4.5, RIPPER, naive Bayesian, etc., is trained from sequential chunks of the data stream. The classifiers in the ensemble are judiciously weighted based on their expected classification accuracy on the test data under the time-evolving environment. Thus, the ensemble approach improves both the efficiency in learning the model and the accuracy in performing classification. An empirical study shows that the proposed methods have substantial advantage over single-classifier approaches in prediction accuracy, and the ensemble framework is effective for a variety of classification models.

Abstract: A method of storing data to one of a first or second storage device associated with a data storage system where each storage device provides for the redundant access to and storage of data within the same logical data volumes. The method of storing data consists of defining a storage construct which will direct the performance of a specific storage function. The storage construct is then associated with a logical data volume. The method further consists of mounting the logical data volume residing on one of the two storage devices and executing a storage function in accordance with the storage construct. The storage construct may be defined by a command issued by a host associated with the data storage system. Alternatively, the storage construct may be defined by a user of the data storage system through a user interface.

Abstract: Method, apparatus and program product are provided for the invalidation of 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 faulty metadata is detected, metadata tracks are selected to be invalidated. A command is received through a host interface, without the controller being taken off-line from the host, and the specified metadata tracks are invalidated. 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 cartridge handling system and method are provided to initialize a data storage cartridge having rewritable media and a cartridge memory for tamper resistant write once recording. During initialization of the cartridge for write once recording, selected data set information table fields of each data set are scrambled. The scrambling algorithm may employ a random number generator seeded with a unique cartridge identifier. The fields thus becomes unreadable if the unique identifier is changed, such as if the cartridge memory of the cartridge has been altered or replaced.

Abstract: Method, apparatus and computer program product are provided to increase the efficiency of copy operations in a data storage system. Multiple virtual storage controllers are each in communication with a host device and to two virtual storage servers. Both virtual storage servers are attached to a respective automated storage library. Each controller includes a copy queue. After directing that a volume of customer data be stored through one of the servers on media in the associated library, an initiating controller queues in a copy queue a request to copy the volume to the other library. If the request is not processed by the initiating controller within a very short period, the initiating controller broadcasts the copy request to the other controllers. Preferably, the copy request is transmitted first from the initiating controller to a routing device in one of the servers which broadcasts the request to each other controller. The copy request is queued in a copy queue of each other controller.

Abstract: A method and user interface are provided for independently and conveniently scaling y-values of multiple data sets whereby the data sets may be plotted against a common y-axis and provide satisfactory variability. A multiplier is selected by which data points in a data set are multiplied, allowing plots of multiple data sets to be graphed against a common range of y-axis values. The initial multiplier may be calculated and selected automatically by the computer on which the graphing is performed or may be manually selected by a user. If the results of the graphing are not satisfactory to the user, the user may change the multiplier for any data set. A spin button may be provided to enable the user to easily increment or decrement a multiplier in predefined steps, such as by factors of 10. Additionally, a computer-generated indicator may be displayed to assist the user in selecting a different multiplier.

Abstract: Disclosed are a system, a method, and a computer program product to provide improved error handling in an embedded system. When the embedded system encounters a fatal error, information pertaining to the error is saved and an indication that the error has occurred is also saved. The embedded system resets itself to allow normal operation to resume. Before or after the reset, the embedded system sets an indication of the prior error so that a human or a machine will be alerted to the fact that the embedded system had encountered the error. At some point in time, the error information may be retrieved, collected or sent for post error analysis. The error flag and/or error status is then cleared to remove the current error condition and/or allow a subsequent error to be managed.

Abstract: A data storage control unit is coupled to one or more host devices and to one or more physical storage units. Data is stored in one of the storage units and, for data integrity, copied to another storage unit. An updated state of the copy process (metadata) is maintained and updated in metadata tracks in a memory of the storage controller and periodically destaged to corresponding metadata tracks of a storage unit. If the copy process is interrupted, such as by a power failure, an error handling routine commences. Track state fields associated with each in-memory metadata track are initialized to an ‘invalid’ state and background staging of metadata tracks from the storage unit to the memory. After a track is staged, the associated track state field is changed to a ‘valid’ state. If a request is received to access a track of copy state data and the track has been staged (as indicated by the state of the associated track state field), the track is accessed.
