  • Patent number: 10896162
    Abstract: Systems and methods to manage database data are provided. A particular method includes automatically identifying a plurality of storage devices. The storage devices include a first device of a first type and a second device of a second type. The first type includes a solid state memory device. The method may further identify a high priority data set of the database. A rebalancing operation is conducted that includes moving the high priority data set to the solid state memory device and substantially evening distribution of other data of the database among the storage devices.
    Type: Grant

  • Patent number: 9734171
    Abstract: The present invention includes a computer-implemented method including, classifying a data set in response to metadata corresponding to one or more data files located on a single database; and creating a data file topology comprising a data file identifier, a data file location and a data file type. The method may also include receiving a predetermined rule directory comprising a set of features corresponding to one or more file systems; and in response to the data file topology and the predetermined rule directory, reorganizing the data set such that at least a portion of the data set is moved to one of a set of new file systems having a predetermined optimized characteristic.

  • Patent number: 9020985
    Abstract: A method and system for automatically and transparently managing a directory in a database system to preferentially use of objects in an in-memory database instead of copies of the objects in disk-based databases, in order to speed up application response times. The methods and systems selectively add or update LDAP entries to leverage advantage of the database objects in the in-memory database, so that the LDAP entries point to the in-memory database instead of disk-based databases.

  • Publication number: 20110145242
    Abstract: Embodiments of the present invention include methods, systems and computer program products. The embodiments of the present invention intelligently distribute data files within a database based upon predetermined conditions. In one embodiment, the present invention includes a computer-implemented method including, classifying a data set in response to metadata corresponding to one or more data files located on a single database; and creating a data file topology comprising a data file identifier, a data file location and a data file type. The method may also include receiving a predetermined rule directory comprising a set of features corresponding to one or more file systems; and in response to the data file topology and the predetermined rule directory, reorganizing the data set such that at least a portion of the data set is moved to one of a set of new file systems having a predetermined optimized characteristic.
