Patent ID: 7650369

Claim:
A database system management method for managing a database system configured by a main center system including a first processing device which generates operation data by executing a transaction constituting an operation according to a request that has been sent via a network from any one of a plurality of operation terminal computers in a normal state and including a first database device which stores the operation data or updates the stored data by new operation data every time new operation data are generated, and a sub-center system including a second processing device and a second database device respectively including the same functions as said first processing device and said first database device, said method comprising: first log information generating, in which said first processing device generates, whenever the operation data are updated within said first database device, its log information as first log information; incorporating in which said first processing device incorporates predetermined first delimiter information into an interval between two consecutive arbitrary pieces of first log information generated in said first log information generating; transmitting in which said first processing device transmits the series of first log information into which the delimiter information is incorporated in said incorporating to said second processing device; updating in which said second processing device divides the series of first log information transmitted in said transmitting into plural groups and executes, for each of the plural groups, update of the operation data stored in said second database device on the basis of the respective first log information constituting the group; second log information generating, in which said second processing device generates, whenever the operation data are updated in said second database device in said updating, its log information as second log information; and storing in which said second processing device incorporates second delimiter information associated with the first delimiter information into an interval corresponding to the interval within the series of second log information generated in said second log information generating and stores the series of the second log information in which the second delimiter information is incorporated.
