Abstract
A method and system allows a part of a database to be restored using a subset of the backup files stored for a database. A working copy of the data dictionary of the database, which stores data definitions, is restored using the latest backup file stored not later than the point in time specified and the names of tablespaces related to the table names specified are identified using the data dictionary. The files storing the database tablespaces specified and those identified as related are identified for restoration along with the point in time specified, so that the backup files may be used to restore the files to the latest time prior to the point in time specified. The database data files are [restored, they] are rolled forward from the point in time of the backup files to the point in time specified, using transaction logs restored with the database data files and the restored working data dictionary is updated as described by the transaction logs. The working data dictionary is then spliced into the database data dictionary, and the database control file is adjusted to point to the restored database data files.
