expdp数据库导出导入

[oracle@huydvm ~]$ expdp

Username: fm

Password: 1

导出的文件默认放在：

/home/oracle/app/admin/orcl/dpdump

2、将上面导出的文件拷贝到另一台机器还原文件所在目录下面；

3、使用sys as sysdba执行 install.sql 创建数据库用户等必要信息；

4、impdp命令：impdp fm/1 dumpfile=expdat.dmp full=y;

?

5、上面导出的文件在另外一个数据库中导入的时候报错如下：

[oracle@localhost dpdump]$ impdp fm/1 dumpfile=expdat20170805.dmp full=y;

?

解决：

PL/SQL procedure successfully completed.

[oracle@localhost dpdump]$ impdp fm/1 dumpfile=expdat20170805.dmp full=y transform=OID:N

6、查看oracle默认导出目录

SELECT directory_path FROM dba_directories WHERE directory_name = ‘DATA_PUMP_DIR‘;

7、设置oracle导出目录

SQL> CREATE DIRECTORY dmpdir AS ‘/opt/oracle‘;

Directory created.

SQL> GRANT read, write ON DIRECTORY dmpdir TO scott;

Grant succeeded.

使用exp和imp进行特定用户数据库的导入和导出

1、从A数据库中把fm用户下的所有内容导入fm.dmp文件；

[fm@huydvm ~]$ exp fm/1@ois buffer=64000 file=./fm.dmp owner=fm
