Techniques for geometric aging data reduction for machine learning applications are disclosed. In some embodiments, an artificial-intelligence powered system receives a first time-series dataset that tracks at least one metric value over time. The system then generates a second time-series dataset that includes a reduced version of a first portion of the time-series dataset and a non-reduced version of a second portion of the time-series dataset. The second portion of the time-series dataset may include metric values that are more recent than the first portion of the time-series dataset. The system further trains a machine learning model using the second time-series dataset that includes the reduced version of the first portion of the time-series dataset and the non-reduced version of the second portion of the time-series dataset. The trained model may be applied to reduced and/or non-reduced data to detect multivariate anomalies and/or provide other analytic insights.

A method, device, and computer readable medium for striping rows of data across logical units of storage with an affinity for columns is provided. Alternately, a method, device, and computer readable medium for striping columns of data across logical units of storage with an affinity for rows is provided. When data of a logical slice is requested, a mapping may provide information for determining which logical unit is likely to store the logical slice. In one embodiment, data is retrieved from logical units that are predicted to store the logical slice. In another embodiment, data is retrieved from several logical units, and the data not mapped to the logical unit is removed from the retrieved data.

Database operation-aware striping technique

The present invention generally relates to computer software, and more specifically, to a computerized utility for analysis of optimized program files. A method and apparatus for optimized program analysis is disclosed.

A method and apparatus for executing groups of database statements is provided. An indication is included in database statements to indicate whether instructions need to be executed in a particular sequence with respect to one another. In an embodiment, statements that need to be executed sequentially with respect to one another are included in the same bundle. In an embodiment bundles do not need to be executed in any particular order with respect to one another. A mechanism has been presented to enable statements to be executed concurrently by the server. In an embodiment, groups of database statements are sent from a client-side to a server within batches including one set of transmission information for the entire batch. In an embodiment, within a batch there may be one or more bundles. In an embodiment, the bundles are always executed sequentially; however, different bundles within a batch can be executed concurrently.

Techniques for representing core files generated by a computer operating system upon crash of a computer program in a generic format are disclosed. A generic representation of the core file can be generated and analyzed to help in determining errors in code that occurred which the operating system is unable to handle. The generic representation of core files can be represented in a platform-independent format, for example, generic representation of core files may be represented in an extensible data format.

A method and apparatus for transparently invoking from a first database management system (DBMS) a stored procedure residing at a second DBMS. The first DBMS initially receives an instruction from a user to execute the stored procedure. In response, an invoking instruction executable at the second DBMS is automatically generated for causing the second DBMS to execute the stored procedure. The invoking instruction is sent to the second DBMS. In response to the invoking instruction, the second DBMS executes the stored procedure and provides the results to the first DBMS, which provides the results to the user. The fact that the stored procedure resides at the second, rather than the first, DBMS is transparent to the user.
