詳細的執行步驟：
1.ltdb導出可傳輸表空間(以sysdba執行導出)到dmp文件。
2.將ltdb的tsts表空間改為只讀。
3.用操作系統命令復制數據文件和dmp文件到另一個位置給另一個數據庫epras使用。
如果在一臺服務器上，dmp文件可以不必復制，復制完成后，將ltdb的tsts表空間改為可讀寫。
4.在epras數據庫創建ts用戶（此時不必授權）。
5.導入可傳輸表空間(以sysdba執行導入)到dmp文件到epras數據庫。
6.將epras的tsts表空間改為可讀寫，給ts用戶授權。
好處很明顯，和數據exp/imp相比，速度很快，dmp文件只包含表空間元數據10g支持不同平臺的表空間傳輸，支持大頭/小頭操作系統之間的傳輸/*
在Oracle以前的版本中,可傳輸的表空間的特性可以讓表空間在相同的體系結構和操作系統之間遷移.
在 Oracle 數據庫 10g 中，這個局限消失了：只要操作系統字節順序相同,您就可以在平臺
之間傳輸表空間。一些操作系統（包括 Windows）在低位內存地址中用最低有效字節存儲
多字節二進制數據；因此這種系統被稱為低地址低字節序。相反，其它的操作系統
（包括 Solaris）將最高有效字節存儲在低位內存地址中，因此這種系統被稱為低地址高字節序。
當一個低地址高字節序的系統試圖從一個低地址低字節序的系統中讀取數據時，需要一個轉換過程
— 否則，字節順序將導致不能正確解釋讀取的數據。
不過，當在相同字節順序的平臺之間傳輸表空間時，不需要任何轉換。
Oracle 10g的表空間跨平臺遷移，與Oracle9i比較就是增加了一個使用Rman進行的文件格式轉換的過程。
實際上僅僅是轉換了數據文件頭的格式信息。

運行rman
rman TARGET /
CONVERT TABLESPACE tswin1,tswin2
TO PLATFORM 'Microsoft Windows IA (32-bit)'
FORMAT '/tmp/rman/%U';
在以上的例子中，轉換后的文件名難于辨認并很難與原始文件關聯還可以使用其它格式來為數據文件命名。
CONVERT TABLESPACE tswin1,tswin2
TO PLATFORM 'Microsoft Windows IA (32-bit)'
db_file_name_convert '/tmp/LTDB','/tmp/rman'
此處將在轉換后保留文件名。
