下面是network_link常用的三个环境测试
1,服务器端的数据导出到指定的客户端
2,不同数据库间迁移数据。
3,同一个数据库中不同用户之间迁移数据。
一:服务器端的数据导出到指定的客户端
- 1,修改客户端的TNSNAMES文件
- POWER1 =
- (DESCRIPTION =
- (ADDRESS_LIST =
- (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.111.13)(PORT = 1521))
- )
- (CONNECT_DATA =
- (SERVER = DEDICATED)
- (SERVICE_NAME = power1)
- )
- )
- 2,创建dblink
- SQL> CREATE PUBLIC DATABASE LINK "POWER1"
- 2 CONNECT TO scott
- 3 IDENTIFIED BY "oracle"
- 4 USING 'POWER1';
- Database link created.
- SQL> select * from dual@power1;
- D
- -
- X
- 3,directory目录
- SQL> set lines 170
- SQL> col owner for a15
- SQL> col directory_name for a60
- SQL> col directory_name for a30
- SQL> col DIRECTORY_PATH for a70
- SQL> select * from dba_directories;
- OWNER DIRECTORY_NAME DIRECTORY_PATH
- --------------- ------------------------------ ----------------------------------------------------------------------
- SYS DUMP /tmp
- SYS TOAD_BDUMP_DIR /u01/app/oracle/diag/rdbms/orcl11g/orcl11g/trace
- SYS XMLDIR /u01/app/oracle/product/11.2/db_1/rdbms/xml

- SYS ORACLE_OCM_CONFIG_DIR /u01/app/oracle/product/11.2/db_1/ccr/state
- 如果不存在使用create directory创建再用grant授予用户权限
- 4,导数据
- [oracle11g@rhel4 admin]$ expdp system/oracle directory=dump dumpfile=scott_test.dmp logfile=scott_log.dmp network_link='power1' schemas=scott

- 回到客户端上面

二,不同数据库间迁移数据
环境接着上面的,这里把源端SCOTT用户的数据迁移到客户端上面的HTZ用户下面

三:同一个数据库中不同用户之间迁移数据
环境接着上面,这里把HTZ的数据库迁移到同一个数据库的SCOTT用户下面
- 1,删除SCOTT用户
- [oracle11g@rhel4 admin]$ sqlplus / as sysdba
- SQL*Plus: Release 11.2.0.3.0 Production on Tue Mar 26 20:30:28 2013

- SQL> drop user scott cascade;
- User dropped.
- SQL> Drop public database link "orcl11g";
- Database link dropped.
- SQL>
- SQL> create public database link "orcl11g"
- 2 connect to htz
- 3 identified by "oracle"
- 4 using 'ORCL11G';
- Database link created.
- SQL> grant exp_full_database TO htz;
- Grant succeeded.
- 2,导数据

三种常用的方式已经测试成功
