ABSTRACT:
A database-rearranging program which is capable of rearranging a database while maintaining high reliability, without stopping services provided by the database. When a request for rearranging the copy source database is input, a record copying module sequentially selects pages in the copy source database, and the records in the selected page are copied to the copy destination database. Further, the record copying module sets a progress of copying of each page of the copy source database to a page status management table. Thereafter, when a request for writing updated records is input, a record writing module refers to the page status management table, and when a page of the copy source database in which the updated records should be written is in an uncopied status, the updated records are written in the page of the copy source database, and when the same is in a copied status, the updated records are written in the copy source database and the copy destination database.
