Abstract:
1. A transaction processing system comprising; a first server comprising a first memory domain and configured to perform a transaction process as a current operation server; a second sever comprising a second memory domain which has a same size as said first memory domain and stores a replica of data stored in said first memory domain; third and fourth servers activated to have third and fourth memory domains, respectively; and a control server configured to monitor a failure of said first and second servers, wherein each of said first to fourth servers comprises: a processing mechanism configured to perform said transaction process and a control between said, servers; said memory domain comprising: a memory domain control mechanism configured to reserve an area for said logical data in said memory domain in response to a memory reserve request from said processing mechanism, to record a position of said logical data as a relative address from said start address in said domain control data, and to locate said domain control data at a predetermined position from said start address of said memory domain, wherein said memory domains of said first to fourth servers are said first to fourth memory domains, respectively, and wherein said memory domain control mechanism of said first server records the position of said logical data in said domain control data as relative position from said start address of said memory domain.
