PURPOSE: To optimize the transmission destination of log data and to efficiently use plural log servers which are connected to a medium and shorten a log processing time by providing a log data transmission destination selection means which selects the transmission destination of the log data by a transaction server.
CONSTITUTION: The transaction server 2 accepts a transaction process request made a transaction client 1 by a transaction request transmission and reception part 3, and a transaction processing part 4 processes the transaction request while using data in a transaction data storage part 5. The transaction processing part 4 passes the processing result history of the processing part 4 to a log gathering part 6 and also transmits the transaction processing result from the request transmission and reception part 3 to the transaction client 1. The log data that the log gathering part 6 gathers are passed to a log data transmission destination selection part 7, which determines whether the passed log data are sent to one specific transmission destination or many unspecified log servers; and the log data are sent from a log data transmission and reception part 9 to the determined log servers 8.
