SYSTEM FOR PROCESSING DISTRIBUTED DATA BASE

摘要

PURPOSE:To enhance a degree of a parallel processing and to improve a response speed by transferring by an indirect method up to a message reception of a transaction execution and by transferring by a direct method after reception. CONSTITUTION:Subtransaction by a site B13 is signaled to start by transmission of a BEGIN signal to the site B13 by an application program 12 of a site A11. The BEGIN signal is transferred to a transaction control part TCM14 which assigns an execution part. The system does not go into a state of waiting immediately after transmission of the BEGIN signal to the site B13 by the application program 12 and transmits the signal to the TEM through the TCM14 until an ACK-BEGIN signal arrives (indirect transmission), and transmits the signal directly to the TEM concerned, after the arrival of the ACK-BEGIN signal (direct transmission).
