System and Method for Automated Online Reorganization of Sequential Access Databases |
摘要 |
Various systems, non-transitory computer readable media, and methods for reorganizing data records of a database are provided. For example, a system may use an efficiency parameter that indicates a satisfactory level of organizational efficiency of at least a portion of a database table having a group of rows stored using a plurality of data blocks. The system may determine an efficiency of the group of rows based on a number of data block changes that occur during a sequential access of the group of rows. When the determined efficiency is less than the efficiency indicated by the efficiency parameter, the server may generate a control card to reorganize the group of rows when the efficiency is not satisfactory. The control card is used by an online reorganization process that reorganizes the group of rows.
