Abstract: A TPC apparatus 12 is configured to be able to access a possessed quantity storage unit that stores a possessed quantity of an asset in a first entity and a possessed quantity of an asset in a second entity and a transaction information storage unit that stores first transaction information and second transaction information indicating a transaction of an asset between the first entity and the second entity. The TPC apparatus 12 determines whether or not a net base transaction based on the first transaction information and the second transaction information is possible by the possessed quantity of an asset in at least one of the first entity and the second entity. The TPC apparatus 12 pays for a transaction indicated by the first transaction information on a gross basis and pays for a transaction indicated by the second transaction information on a gross basis when it is determined that the net base transaction is possible.

Abstract: There is provided a transaction control system enabling, even when a message having incomplete data is input, a service provider to independently correct the incomplete data to make a retry, without exerting influence on processing of the subsequent message and without increasing the operation burden of an operator. A business application acquires a first message from a first queue after starting transaction processing, checks whether identification information has been recorded in an exception-management table, and performs business processing when no record has been made. The business application outputs a third message including the contents of the first message to a third queue according to exception processing when the record has been made, and commits the transaction processing.
