oracle9i에서는 지정된 tablespace의 object를 export 받기위한 옵션으로 tablespace parameter를 사용할 수 있게 되었습니다. (8i에서 이 parameter는 다른 데이터베이스로 옮길 테이블스페이스를 지정하였으나 9i에서는 지정된 테이블스페이스의 object를 export 하겠다는 개념으로 바뀜)
이 parameter를 사용하기 위해서는 해당 user에게 export_full_database privilege가 부여되어 있어야 하는데 아래의 예제를 보면서 이해 바랍니다.

===================================================================
한가지 특이한 점은 지정된 tablespace 내의 object와 연관된 다른 tablespace의 object도 같이 export/import 된다는 것이다.
