  • System and method for rebuilding indices for partitioned databases
    Patent number: 8694472
    Abstract: A method comprises storing a partitioned database comprising a plurality of partitions, wherein each of the plurality of partitions comprises a respective set of data records. The method continues by storing at least one secondary index associated with each of the plurality of partitions. The method continues by taking offline each of the plurality of partitions. The method continues by unloading data records from each of the plurality of partitions. The method continues by loading the data records into the partitioned database. The method continues by, in conjunction with loading the data records, modifying the at least one secondary index. The modification of the at least one secondary index comprises determining a partition identifier and a memory address associated with a particular data record loaded into the partitioned database.

  • System and method for online reorganization of a database using flash image copies
    Publication number: 20070282878
    Abstract: A method for reorganizing a database comprises receiving at least one update to a first database. The method continues by generating a copy of the first database. The method continues by generating a shadow database, wherein the shadow database represents a reorganized version of the first database and is based at least in part on the copy of the first database. The method continues by applying the at least one update to the shadow database. The method concludes by replacing the first database with the shadow database.

  • Method and system for online reorganization of databases
    Patent number: 7117229
    Abstract: A system and method for online reorganization of an existing database that occurs while read and update activity of the existing database continues. The system and method comprise unloading the existing database, reloading the existing database directly to a shadow database, building shadow database indexes, creating a first intermediary image copy of the existing database, analyzing the existing database, capturing updates for the existing database, applying the captured updates to the shadow database, taking the existing database offline, finalizing the shadow database with any remaining updates, creating a final image copy, comparing the existing database and the finalized shadow database, and placing the finalized shadow database online.
