  • Workload manager for relational database management systems
    Publication number: 20070299812
    Abstract: A relational database workload manager is provided for dynamically managing processing priorities assigned to queries executing within a relational database management system (RDBMS). The workload manager monitors executing query process threads and at set time intervals reduces the processing priority assigned to each executing query. This automated method of managing relational database queries allows short executing queries within a mixed database workload to remain relatively quick without complicated setup and management.

    Abstract: A secure relational database system is provided which utilizes a non-invasive encryption technique. Data pages stored or retrieved by a relational database management system are diverted to a multi-channel hardware encryption engine for processing. Each data page is divided into multiple buffers and distributed among the channels of the hardware encryption engine to be processed simultaneously. The data page is then reassembled and passed on to its intended destination.
