--查看所有的dblink;
       
 select * from dba_db_links;

--新建dblink（public为所有的用户使用，不写public则只是用户自己使用）

 create public database link DB_LINK --(名字自定义)
   connect to ADMIN  identified by "ADMIN" 
   --connect to 账号 identified by 密码
   using '(DESCRIPTION =  
      (ADDRESS_LIST =  
          (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.100.100)(PORT = 1521))  
      )  
      (CONNECT_DATA =  
        (SERVICE_NAME = orcl)  
      )  
  )';
  

--删除dblink
      drop  database DB_LINK;
      drop  public  database link DB_LINK;
