A conductor transmits a commit processing request to directors in response to a commit request received from an application. Upon receipt of a response to the commit processing request from any one of the directors, the conductor notifies the application of a successful commit. If there is a pending transaction due to a failure in a director, the conductor instructs the director to process the pending transaction upon recovery from the failure. If a failure occurs in the conductor during transmission of the commit processing request and the commit processing request is not received by any of the directors, the conductor inquires the director whether there is a pending transaction after recovery from the failure, and instructs the director to process the pending transaction based on a processing result of the pending transaction obtained from another director.
