Oracle 11g远程导出数据库

Oracle 11g远程导出数据库,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OEL

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.
