Abstract
When a trigger and a method for changing partition definition information have been defined, a DBMS monitors the occurrence of the trigger. When the occurrence of the trigger is detected, a specified partition change is executed automatically. When the partition change is executed, migrations of data among storage areas are executed in parallel as long as the migration source storage area and the migration destination storage area of one piece of the data do not overlap those of another piece of the data.
