下面演示下使用数据泵的NETWORK_LINK将OEL6.0 Oracle 11gR2数据库中STORAGE用户下的所有对象迁移到OEL5.7 ORACLE 11gR2数据库中STORAGE用户下。
1.创建TNS字符串
FHACDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.20.101)(PORT = 1523))
)
(CONNECT_DATA =
(SERVICE_NAME = fhacdb)
)
)
2.创建DIRECTORY并授权
SQL> create directory imp as '/home/oracle'; Directory created.
SQL> grant read,write on directory imp to storage;
Grant succeeded.
3.创建DB_LINK
SQL> create public database link l_storage connect to storage identified by storage using 'fhacdb';
Database link created.
4.使用IMPDP的NETWORK_LINK进行迁移操作
[oracle@www.linuxidc.com admin]$ impdp storage/storage directory=imp network_link=l_storage
