Oracle数据泵远程导入数据

1. 查看现存镜像目录

   select * from dba_directories;

2. 创建镜像目录

   create or replace directory my_dir as 'local_dir' ;

3. 把镜像目录的权限赋予所需用户

   grant read,write on directory my_dir to oracle_user_name;

4. 创建dblink

   create public database link link_80

   connect to remote_oracle_user_name identified by password

   using '(DESCRIPTION =

   (ADDRESS = (PROTOCOL = TCP)(HOST = remote_oracle_IP)(PORT = 1521))

   (CONNECT_DATA =

   (SERVER = DEDICATED)

   (SERVICE_NAME = remote_oracle_instancename)

   )

   )';

   检查是否创建成功

   select * from dba_db_links;

5. 导数据

   表模式导入：

   impdp local_oracle_user_name/password tables=remote_table_name1,remote_table_name2,remote_table_namen remap_schema=remote_oracle_user_name:local_oracle_user_name directory=my_dir network_link=remote_database_link

    

   用户模式导入：

   impdp \'\/ as sysdba \' directory=DATA_PUMP_DIR1 network_link=link_160 schemas='TEST3' REMAP_TABLESPACE=TEST3:TEST
