    • A method and system presents an online reorganization of at least a portion of a database. The database includes a plurality of rows stored in a plurality of physical blocks and the rows are categorized by a plurality of reference groups. The database manager is operable to identify a target subset of physical blocks based, at least in part, on one of the reference groups and to identify a source subset of physical blocks associated with the particular reference group. The database manager is further operable to dynamically move the rows stored in a first physical block in the source subset to a second physical block in the target subset while the database is online.
    • 方法和系统呈现数据库的至少一部分的在线重组。 数据库包括存储在多个物理块中的多行,并且行由多个参考组分类。 数据库管理器可操作以至少部分地基于参考组之一来识别物理块的目标子集,并且识别与特定参考组相关联的物理块的源子集。 数据库管理器还可操作以在数据库联机时将存储在源子集中的第一物理块中的行动态移动到目标子集中的第二物理块。

    • 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.
    • 提供了各种系统,非暂时性计算机可读介质和用于重组数据库的数据记录的方法。 例如,系统可以使用效率参数,其指示具有使用多个数据块存储的一组行的数据库表的至少一部分的组织效率的令人满意的级别。 系统可以基于在该组行的顺序访问期间发生的数据块更改的数量来确定该组行的效率。 当确定的效率小于效率参数所表示的效率时,服务器可以生成控制卡以在效率不令人满意的情况下重组该组行。 控制卡由重组组织的在线重组过程使用。

    • Various systems, non-transitory computer readable media, and methods reorganize data records of a database in response to an efficiency parameter. 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.
