In this database system, an active system server has a first execution unit, which executes a plurality of first sub-execution units in a parallel manner, and an integrated log management unit. The plurality of first sub-execution units executed in a parallel manner perform a plurality of transactions with respect to a first database managed by the active system server, generate a plurality of logs, each corresponding to a respective one of the plurality of transactions, and writes each of the generated plurality of logs to a corresponding one of a plurality of log storage regions. The integrated log management unit reads the plurality of logs from the plurality of log storage regions, generates an integrated log including the read plurality of logs, and transfers the generated integrated log to a standby system server. |
