摘要： A database management system (DBMS) generates a query execution plan including information indicating one or more database (DB) operations necessary to execute the query. The DBMS dynamically generates a task for executing the DB operation in execution of the query. The DBMS performs a determination processing of simultaneous-task-generation number when newly creating a task. The determination processing of simultaneous-task-generation number is to calculate the number of simultaneous task generation, which is the number of tasks that can be generated simultaneously, based on the number of tasks which can be newly generated, a first memory resource amount which is the amount of memory resources necessary to be allocated per task newly generated, and a second memory resource amount which is the number of memory resources that can be newly allocated. The number of tasks generated dynamically and simultaneously is equal to or smaller than the calculated number of simultaneously generatable tasks.

摘要： A management system manages a plurality of data units constituting schemas of a database in a storage device, which includes a plurality of first storage device sets having a plurality of storage areas. An ordered schema constituted of the plurality of data units having order properties defining respective orders is included in the schemas. When a second storage device set, which is a set of one or more second storage devices and in which each of the storage areas is a free storage area, is added to the first storage device set, the management system migrates two or more data units not consecutive in the order among a plurality of data units stored in the plurality of storage areas in the first storage device set respectively from at least the one first storage device set to the free storage areas of the second storage device set.

摘要： Provided is a database management system coupled to a storage system comprising a first storage device for storing a database file and a control file, a second storage device for storing a journal corresponding to an update history of the data stored in the first storage device, and a third storage device for storing a log file; generating the journal upon receiving an update instruction; and recording the generated journal to the second storage device in correspondence with a check point. The database management system records the log to the third storage device in correspondence with identification information of the generated check point, restores data stored in the storage system by employing a journal stored in the second storage device before check point, and applies the log stored in the third storage device after the check point to restore a database file.
