EXP-00106: Invalid Database Link Passwords
EXP-00000: Export terminated unsuccessfully

查資料庫中唯一的一個DBLINK是正常的，密碼正確。

解決辦法：
升級資料庫到11.2.0.4版本；

網上參考：

If you encounter EXP-00106: Invalid Database Link Passwords, you may better use Data Pump instead of the old export utility (exp).
Another solution is to drop the database links before running export.
Or install the client patch to Version 11.2.0.3:
Goto Under the Patches and Updates tab search for *10404530*
A list of Oracle 11.2.0.3 software will be listed.
Select the software version which matches your operating system, download and install it.
