unless I am misreading the 9i docs (see below) this has nothing to do with transportable tablespaces
If you use DESTROY=Y and a full database import, Oracle will overwrite the datafiles as defined in the create tablespace statement that is in the dump file. It's the equivalent of issuing: create tablespace <tbsname> datafile '<prod file name>' reuse; >From the 9i Utilities manual: "Specifies whether or not the existing datafiles making up the database should be reused. That is, specifying DESTROY=y causes Import to include the REUSE option in the datafile clause of the CREATE TABLESPACE statement, which causes Import to reuse the original database's datafiles after deleting their contents. Note that the export file contains the datafile names used in each tablespace. If you specify DESTROY=y and attempt to create a second database on the same system (for testing or other purposes), the Import utility will overwrite the first database's datafiles when it creates the tablespace. In this situation you should use the default, DESTROY=n, so that an error occurs if the datafiles already exist when the tablespace is created. Also, when you need to import into the original database, you will need to specify IGNORE=y to add to the existing datafiles without replacing them.
