Abstract
A method, system and computer program capable of executing a transaction in a scalable manner by dividing and then executing the transaction in a distributed environment. In an embodiment of the invention, a system divides and then executes a transaction in a distributed environment. The system includes means which divides the transaction processing into an optimistic process which unlikely causes conflicts and a pessimistic process which likely causes conflicts; a first server; and a second server. The first server includes a first transaction execution unit for executing the optimistic process; and a transaction log transmission unit for transmitting a result of the execution of the optimistic process to the second server. The second server includes a transaction log receiving unit for receiving the transmission log; and a second transaction execution unit for executing the pessimistic process.
