T (T)-tree index structure recovery method in a distributed main memory database (DBMS)

摘要

The present invention relates to a method for recovering a T-tree index structure in a distributed real-time main memory database (DBMS) in an asynchronous transfer mode (ATM) exchange. The present invention receives a transaction command to update a tuple database area and a meta database area, and does not create a log of a T-tree index structure for updating an MMDB (Main Memory Database) By regenerating the structure, it is possible to increase the performance of the system by recovering the MMDB and speeding up the processing when the transaction is completed and committed. In addition, since only a part of the MMDB is kept on the disk, the loading time of the disk DBMS image can be reduced in the initial operation and recovery of the system.
