  • Patent number: 6131094
    Abstract: A method in a symmetric multi-processor computer system for increasing database transaction log performance by pipelining transaction log buffers. The method includes the steps of inserting a log record into a log buffer stored in a volatile memory of the computer system. Next, the log buffer is queued for eventual delivery to a persistent storage device. Then the log buffer is dequeued from the queue set in the previous step. Following this, a transfer of the contents of the log buffer to the persistent storage device is initiated. A wait is imposed on the process for the completion of the transfer of the contents of the log buffer to the persistent storage device in order to guarantee that the contents are safely stored in the persistent storage device in the original serial order as received.
