Restore_Options=file-name Generates an options file designed to be used with the Options qualifier of the RMU Restore command. The Restore_Options file is created by reading the database root file. Therefore, there is no guarantee that this options file will work with all backup files you attempt to restore with a Restore operation. For example, if areas have been added or deleted from the database since the backup file was created, there will be a mismatch between the Restore_Options file and the backup file. Similarly if the backup file was created by a backup by-area operation, the Restore_Options file may refer to areas that are not in the backup file. By default a Restore_Options file is not created. If you specify the Restore_Options qualifier and a file, but not a file extension, Oracle RMU uses an extension of .opt by default.
