  • Technique to avoid processing well clustered LOB's during reorganization of a LOB table space
    Patent number: 6535895
    Abstract: A method, apparatus, and article of manufacture for a computer implemented reorganization system. A table space is reorganized in a database stored on a data storage device connected to a computer. When inserting or updating a LOB into a portion of the table space, a space map is marked to indicate whether the LOB was well inserted. When reorganizing the table space, when the space map indicates that a LOB was well inserted, reorganization of the portion of the table space in which the LOB was well inserted is avoided.
