    摘要: A cache consistency maintenance procedure to select one of a detection-based cache consistency maintenance procedure optimized for record-based locking and an avoidance-based consistency-based maintenance procedure optimized for table and block-based locking. To support the characteristic of DBMS in which table locking and record locking are consistent to access the same table, the two kinds of the consistency maintenance policies for the same block are processed by a single buffer load process and the two kinds of the consistency maintenance policies are consistent with each other to provide better configuration and performance.

    摘要: A concurrency control method for a high dimensional index structure that provides efficient concurrency control method for a high dimensional index structure, which performs reinsertion of certain objects to cope with node overflow. The concurrency controlled searching method includes the following steps. First, an entry is obtained from a queue storing the root node and an object relating to the entry is selected. Second, whether a logic sequence number (LSN) of a lower level node is larger than an expected LSN stored in the upper node is determined. Third, the process moves to a neighbor node of the lower level node if the LSN is bigger than an expected LSN stored in the upper node in the second step, selects a relating object, and performs from the second step repeatedly. Fourth, an object of a node of a level corresponding to the lower level node in a reinsertion table is selected when a search on an index tree is finished if the LSN is not bigger than the expected LSN stored in the upper node in the second step.
