Oracle EXP-00091解決方法

 

 

 

 

 

 

 

非交互式

 

windows: D:\>exp scott/tiger file=employee.dmp tables=(emp,dept)

linux需要加雙引號

 

EXP-00091:

[oracle@oracle oracle_databak]$ exp scott/orcl@orcl file=/home/oracle/oracle_databak/scott.dmp tables="(emp,dept)"

處理方法

如果在exp后指定rows=n 意思就是不導出數據，只導出表結構

解決方式：EXP-00091   對環境變量進行修改 修改后重新進行導出操作就沒有這個錯誤了

 

 

select * from v$nls_parameters where parameter='NLS_CHARACTERSET';

 

imp導入操作

 

[oracle@oracle ~]$ imp system/orcl@orcl file=/home/oracle/oracle_databak/scott.dmp fromuser=scott touser=nod commit=y
