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

查数据库中唯一的一个DBLINK是正常的，密码正确。

解决办法：
升级数据库到11.2.0.4版本；

网上参考：http://ora11g.de/EXP-00106.html

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 https://support.oracle.com. 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.
