    • There is provided a technique capable of executing a predetermined processing while continuing a database processing. Firstly, the database to be operated is switched from the main database to a duplicate database. The predetermined processing is executed to the main database which becomes the non-operation mode by the switching. Next, a database access request is distributed to the duplicate database which becomes the operation mode by the switching, thereby performing the database processing. Update information indicating the content of the update processing performed to the duplicate database is output. The output update information is reflected on the main data base for which the predetermined processing has been executed. After this, the database to be operated is switched from the duplicate database to the main database.
    • 提供了一种能够在继续数据库处理的同时执行预定处理的技术。 首先,要运行的数据库从主数据库切换到重复的数据库。 对通过切换成为非操作模式的主数据库执行预定处理。 接下来,通过切换将数据库访问请求分发到成为操作模式的重复数据库,从而执行数据库处理。 输出指示对重复数据库执行的更新处理的内容的更新信息。 输出更新信息反映在执行了预定处理的主数据库上。 之后,要运行的数据库从重复数据库切换到主数据库。
