2.处理方法
指定Linux系统的NLS_LANG环境变量为数据库的数据集
1)查询数据库的字符集(方法很多只用一种)
SQL> select userenv('language') from dual;
USERENV('LANGUAGE')
----------------------------------------------------
AMERICAN_AMERICA.WE8ISO8859P1
2)设置Linux操作系统的NLS_LANG环境变量
[oracle@RH207 exp]$export NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1
Window系统的环境变量的修改方法是:
C:\>set NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1
3.OK,处理完成,在进行EXP导出操作就不会报这个错误了
