一.出現EXP-00091錯誤
[oracle@test4 ~]$ exp system/oracle file=/oracle/dump/daochu1 log=daochu1.log full=y

當環境變量和數據庫的不一致，在導出統計信息時候，會報EXP-00091錯誤。
二.查看NLS相關參數
[oracle@test4 ~]$ echo $NLS_LANG
SQL> col value fora30
SQL> selectparameter,value fromnls_database_parameters
2 whereparameter like'%CHARACTERSET%';
PARAMETER VALUE
------------------------------ ------------------------------
NLS_CHARACTERSET UTF8
NLS_NCHAR_CHARACTERSET UTF8
三.解決方法
1.設置NLS_LANG爲NLS_CHARACTERSET
[oracle@test4 ~]$ export NLS_LANG=american_america.UTF8
[oracle@test4 ~]$ exp system/oracle file=/oracle/dump/daochu1 log=daochu1.log full=y
