1、创建TNS字符串: zqxt = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 132.97.172.186)(

1、创建TNS字符串:
 zqxt =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 132.97.172.186)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = ora11g)
    )
 )
 2、查询远程数据的表空间SQL:
 
  1)、select distinct 'select dbms_metadata.get_ddl(''TABLESPACE'','''||tablespace_name||''') from dual;' from dba_tables; 获得各个表空间的查询SQL。
 
  2)、再用查询到的SQL执行查到该表空间的创建SQL(DLL)语句。
 
3、依据第2步的结果创建表空间。
 
4、查询远程用户的角色权限及所属表空间:
 
    select * from user_role_privs;
 
    select username,default_tablespace from user_users;
 
5、依据第4部的结果创建用户,,并赋予权限、角色及所属表空间。

CREATE USER ityy_zqfw
  IDENTIFIED BY zqfw123  DEFAULT TABLESPACE TBS_ITYY
  TEMPORARY TABLESPACE TEMP
  PROFILE DEFAULT
  ACCOUNT UNLOCK;

GRANT CONNECT,CTXAPP, DBA ,RESOURCE TO ityy_zqfw;

grant read,write on directory DATA_PUMP_DIR to ityy_zqfw;

6、创建DB_LINK
 create public database link zqxt connect to ityy_zqfw identified by zqfw123 using 'zqxt';
 
7、使用IMPDP的NETWORK_LINK进行迁移操作
 
      impdp ityy_zqfw/zqfw123 directory=DATA_PUMP_DIR network_link=zqxt logfile=ityy.log
 执行结果如下:
