    Abstract: A system and method for extracting and forecasting computing resource data such as workload consumption of mainframe computing resources using an autoregressive model. The system and method foresast mainframe central processing unit (CPU) consumption with ninety-five percent accuracy using historical perfomance data. The system and method also provide an upper ninety-five percent confidence level and a lower ninety-five percent confidence level. The system and method retrieve performance records from a computer platform in one second intervals, statistically collapses the one second performance data into fifteen minute performance data, statistically collapses the fifteen minute performance data into a one week performance data, and generates a time series equivalent to collecting performance data at one week intervals. The system and method ensure that the resulting time series is statistically stationary, and applies an autoregressive construct to the time series to generate forecast of future CPU utilization, as well as to generate reports and graphs comparing actual vs. forecast CPU utilization. Because the system and method rely on electronically generated empirical historical computer performance data as an input, they provide a turnkey solution to CPU consumption forecasting that can be implemented easily by any system network manager.

    Abstract: A method for implementing transaction-consistent resource recovery from catastrophic media failures in a single pass over a recovery log archive while permitting most UNDO log records to be discarded during log archiving. The media recovery procedure is based on a pseudo-crash recovery technique that simulates a system crash at a selected time by writing pseudo-recovery records to the recovery log. Resource recovery is then performed by normal execution of the log archive records up to the most recent pseudo-crash followed by execution of the subsequent pseudo-recovery records. The recovery log record execution procedures are based on the ARIES recovery method. One embodiment of this invention assumes that the recovery log records can be selected for archiving on the basis of a combination of record type and transaction identifier.

    Abstract: A graphical system resource monitor is provided to depict, in real-time, a data processing system's internal resource utilisation. A window or viewport 120 of a data processing system displays user specified internal system resources, such as memory, CPU, or peripheral device availability/utilisation. This graphical representation of the 'state' of the data processing system's resources is maintained in real-time, while the impact on the system's performance in providing such information is kept to a minimum. This is accomplished through a combination of various techniques, including specialized device drivers for the respective devices coupled with a unique data reduction technique. The graphical results of these resource monitors are continually updated in real-time. Absolute minimum and maximum values are similarly graphically depicted to enhance usability, and calibrate a user to the graphical information being presented. This real-time support provides an immediate and accurate representation of the internal operations of the data processing system. Further, these resources can be monitored at the process level of a multiprocessing system. These representations can be used by a user to identify, isolate, and fine-tune the data processing system's resources to improve the overall efficiency of the system being monitored, as the values being monitored, and their respective variables, can be dynamically modified by a user of the system.

    Abstract: A facility is provided for storing in a backup memory (30-1-P) only those blocks of a file, or disk partition, which differ from corresponding blocks forming an earlier version of the file. Specifically, a file is divided into a number of blocks and a "signature" is generated for each such block. A block is then stored in the backup memory only if its associated signature differs from a signature generated for an earlier version of the block. In addition, if two blocks of the current version of the file have identical signatures and are to be stored in the backup memory, then only one of the two blocks is stored in the memory and a simple message indicating that the other block is equal to the one block is stored in the memory for the other block. Further, the application of such signatures is advantageously applied to the opposite case of restoring a file using copies of previous versions of the file that are stored in the backup memory.
