centos 安装oracle 11g r2（四）-----修改字符集为ZHS16GBK

一、查询两个库的字符集

select userenv('language') from dual;

源端：

SQL> select userenv('language') from dual;

USERENV('LANGUAGE')

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

AMERICAN_AMERICA.ZHS16GBK

目标端：

SQL> select userenv('language') from dual;

USERENV('LANGUAGE')

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

AMERICAN_AMERICA.AL32UTF8
