    • A system and method autonomically reallocate memory among buffer pools to permit quick access to data. A simulated buffer pool extension (SBPX) is created for each buffer pool in a set of buffer pools. Data victimized from a buffer pool is represented in the associated SBPX. Requests for data that is not resident in a buffer pool but is represented in the associated SBPX are tallied. Periodically, an expected efficiency benefit of increasing the capacity of each buffer pool is determined from the tallies. Memory is reallocated from the buffer pool with the lowest expected efficiency benefit having remaining reallocatable memory to the buffer pool with the highest expected efficiency benefit having remaining reallocatable memory, until either one or both of the buffer pools exhausts its reallocatable memory. This process is repeated until all reallocatable memory has been reallocated, until only one buffer pool with reallocatable memory remains, or until all buffer pools with remaining reallocatable memory have substantially the same expected efficiency benefit.
    • 系统和方法在缓冲池中自动重新分配内存,以便快速访问数据。 为一组缓冲池中的每个缓冲池创建模拟缓冲池扩展(SBPX)。 从缓冲池中受害的数据在关联的SBPX中表示。 对不驻留在缓冲池中但在关联的SBPX中表示的数据的请求进行计数。 定期地,从提示中确定增加每个缓冲池容量的预期效率效益。 从缓冲池中重新分配内存,将预留效率最低的优点在于具有剩余可重新分配内存到具有剩余可重新分配内存的最高预期效率优势的缓冲池,直到缓冲池中的一个或两者都耗尽其可重新分配的内存。 重复此过程,直到所有可重新分配的内存已重新分配,直到只有一个具有可重新分配内存的缓冲池保留,或者直到具有剩余可重新分配内存的所有缓冲池具有基本相同的预期效率优势。

    • The retrieval of distinct tuples in a relational database management system. In response to a request from a consumer process for distinct tuples in a relational database table matching a defined criteria, a distinct operator component sequentially requests tuples from a source component. The source component access the database table and returns a tuple in the sequence to the distinct operator component. The distinct operator component passes each tuple in the sequence to an auxiliary logger. The auxiliary component receives a tuples from the distinct component and determines if it is distinct from other previously received tuples in the sequence to verify its uniqueness to the distinct operator. Tuples that are verified as unique by the auxiliary logger are returned to the consumer process by the distinct operator upon verification.
    • 在关系数据库管理系统中检索不同的元组。 响应于来自消费者进程的针对匹配定义的标准的关系数据库表中的不同元组的请求,不同的运营商组件从源组件顺序地请求元组。 源组件访问数据库表,并将序列中的元组返回到不同的运算符组件。 不同的运算符组件将序列中的每个元组传递给辅助记录器。 辅助组件从不同组件接收元组,并确定它是否与序列中其他先前接收的元组不同,以验证其与不同运算符的唯一性。 通过辅助记录器验证为唯一的元组在验证时由不同的运算符返回给消费者进程。
