oracle中expdp和impdp如何导出导入表空间

小编给大家分享一下oracle中expdp和impdp如何导出导入表空间，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！

[oracle@hr1 opt]$ mkdir -p infor1

SQL> create directory scprd as '/opt/infor1';


Directory created.


SQL> grant read,write on directory scprd to system;


Grant succeeded.

[oracle@hr1 opt]$ expdp system/oracle@HR dumpfile=tablespace_hr.dmp schemas=hr2 DIRECTORY=hr LOGFILE=hr2_exp.log

[oracle@hr1 opt]$ impdp system/oracle@HR directory=hr dumpfile=tablespace_hr.dmp remap_schema=hr2:hr6, remap_tablespace=hr2_DATA:hr6_DATA logfile=hr6_imp.log

用remap实现schema和tablespace的导入。

有时候import会报错：
