[日期:2014-11-06] 来源:Linux社区  作者:彭小波 [字体:]

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,
处理方式如下:

1.问题现象
[Oracle@node1]$ exp test/test file=/home/oracle/test20141104.dmp log=/home/oracle/test20141104.log buffer=67108864
……忽略……
EXP-00091: Exporting questionable statistics.
 EXP-00091: Exporting questionable statistics.
 EXP-00091: Exporting questionable statistics.
 . . exporting table                        test      12 rows exported
 EXP-00091: Exporting questionable statistics.
 . . exporting table                users      129 rows exported
 EXP-00091: Exporting questionable statistics.
 EXP-00091: Exporting questionable statistics.
 EXP-00091: Exporting questionable statistics.
 EXP-00091: Exporting questionable statistics.
……忽略……

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@node1]$ $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.
