Use this dialog box to restore data and archive logs.
Restore Data
Specifies whether to restore datafiles from the specified full backup. When cleared, the system does not restore datafiles.
Data is restored from the latest full backup only. If you have performed incremental backups and need to apply this data to the full backup, see the description of the Recover option below.
-
To Point In Time
Specifies that the system will restore data files from the full backup created at or before the point-in-time based on the date and time that you specify. For a Point-in-Time recovery, you should have all log files available up to that time.
To change the date, click one in the list. Also, use the space to set the appropriate time. Ensure that the date/time that you enter is equal to or later than the date and time that the backup completed. Also, ensure that the date/time to which the datafiles are restored is earlier than or equal to the date and time of the control files restore.
Restore Archive Log
Specifies whether to restore the archive log files.
-
If the archived log files exist in the LOG_ARCHIVE_DEST location and are not corrupted, the backed up archive log files are not restored.
-
If the archive log files do not exist or are unusable, the backed up archive log files are restored to the directory specified in LOG_ARCHIVE_DEST.
When cleared, the system does not restore the archive log files.
