Abstract: A joiner accesses a first sorted dataset and a second sorted dataset. Each dataset includes a corresponding plurality of data blocks, each including a set of records. Each record is associated with a corresponding record key. A set of first records for each first data block of the first dataset is arranged based on values of the first record keys. A set of second records for each second data block of the second dataset is arranged based on values of the second record keys. A first root element is extracted from the first sorted dataset. A second root element is extracted from the second sorted dataset. In response to determining that the first and second root elements match, an output is generated by joining the first record associated with the first root element with the second record associated with the second root element.

Abstract: A database server is configured to receive input data which includes a data table. Each record of the table includes a record key and one or more entries. Each of the one or more entries is associated with a corresponding column key of the data table. Instructions are received for sorting the input data according to the column key. The instructions indicate an order in which to sort the input data. Based on the order indicated by the instructions, a pluggable sorting index associated with a column key of the data table is generated. The pluggable sorting index includes the record keys arranged in a sorted order according to sortable properties of entries associated with the column key. A sorted dataset which includes the entries associated with the column key arranged according to the sorted order of the pluggable sorting index is generating using the pluggable sorting index.

Abstract: A technique for reducing harmonic vibration in a multiplex multi-pump system. The technique includes establishing a lower bound of system specific vibration-related information such as via pressure variation or other vibration indicator. Establishing the lower bound may be achieved through simulation with the system or through an initial sampling period of pump operation. During this time, random perturbations through a subset of the pumps may be utilized to disrupt timing or phase of the subset. Thus, system vibration may randomly increase or decrease upon each perturbation. Regardless, with a sufficient number of sampled perturbations, the lower bound may be established. Therefore, actual controlled system operations may proceed, again employing random perturbations until operation of the system close to the known lower bound is substantially attained.

Abstract: Embodiments of the invention relate to systems, methods, and computer program products for a high performance data copy utility that is operable to dynamically copy data from a source database to a target database in an object-relational database environment. High performance is realized by defining, prior to copying the data, performance boundaries of the source and target environment, such as the quantity of data (i.e., commit points) and quantity of parallel processes (i.e., parallel threads) applicable to a copy job. Moreover, the copying schema of the present invention allows for data to be copied from one database to another database without the need higher level privileges, such as database administrator (DBA) or data definition language (DDL), which would otherwise require changing the structure of the database. In this regard, embodiments of the present invention rely solely on lower-level data manipulation language (DML) privileges configured for inserting, updating and deleting data structures.
