expdp&impdp数据库导入导出操作

expdp工具导出的步骤：

1、创建DIRECTORY

[oraarp@arpdb-n1 ~]$ mkdir -p /arp/oraarp/expbackup

SQL>create directory expbk as '/arp/oraarp/expbackup';

2、授权

SQL>grant read,write on directory expbk to arp;

--查看目录及权限

SQL>SELECT privilege, directory_name, DIRECTORY_PATH FROM user_tab_privs t, all_directories d

 WHERE t.table_name(+) = d.directory_name ORDER BY 2, 1;

3、执行导出

SQL>expdp arp/arp schemas=arp directory=expbk dumpfile =arp20150415_1624.dmp logfile=arp20150415_1624.log;

 

 

impdp工具导入的步骤:

1.创建DIRECTORY

[oraarp@arpdb-n1 ~]$ mkdir -p /arp/oraarp/expbackup

SQL>create directory expbk as '/arp/oraarp/expbackup';

 

[root@localhost oraarp]# chown -R oraarp:oinstall expbackup/

 

2.授权

SQL>grant read,write on directory expbk to arp;

SQL>grant read,write on directory expbk to conow;(其他用户)

 

3.impdp工具导入

 

转换schema

[oraarp@arpdb-n1 ~]$impdp conow/conow directory=expbk dumpfile =arp20150415_1624.dmp logfile=arp20150415_1624.log   remap_schema=arp:conow

 

直接导入

[oraarp@arpdb-n1 ~]$impdp arp/arp7101 DIRECTORY=expbk DUMPFILE=arp20150320.dmp logfile=arp20150320.log
