---------------------------------------------------------------------------------------------------

solution:

1.select name,value$ from props$ where name='NLS_CHARACTERSET';

NAME
------------------------------
VALUE$
--------------------------------------------------------------------------------
NLS_CHARACTERSET
ZHS16GBK

2.在用户的属性文件(.profile或者.bash_profile具体看你使用哪种shell)

加入:NLS_LANG=AMERICAN_AMERICA.ZHS16GBK;export NLS_LANG

3:重新连接用户su - user

4:ok
