在使用EXP工具进行导出备份或迁移数据的时候有时会报很多的“EXP-00091: Exporting questionable statistics”错误,具体的现象和处理方法请观看……

1.问题现象

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.处理完成,在进行EXP导出操作就不会报这个错误了
