| Abstract: | A multithreading disaster tolerance backup log transmission system was devoloped based on Oracle Dataguard software. The system support all kinds of host hardware system, and its transmission rate was improved to 10 times higher than the Oracle software. MD5 checksum algorithm was applied to automaticly resume the broken transmission, and the reliability of database log transmission was improved. |
