DB Link 去除域名

1.查看global_name的设置

SQL> show parameters global_name;

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
global_names                         boolean     FALSE

 

默认情况下就是false

 

2.查看GLOBAL_NAME

 

SQL> SELECT * FROM GLOBAL_NAME;

GLOBAL_NAME
--------------------------------------------------------------------------------
HXL.REGRESS.RDBMS.DEV.US.ORACLE.COM

 

看到了吧,hostname(HXL)之后加了一串长长的尾巴.

 

3.查看之前创建的DB Link

SQL> select db_link from dba_db_links;

DB_LINK
--------------------------------------------------------------------------------
P605_DB.REGRESS.RDBMS.DEV.US.ORACLE.COM

 

4.更新global_name

SQL> update GLOBAL_NAME
  2    set GLOBAL_NAME='HXL';

1 row updated.

SQL> commit;

Commit complete.

 

5.重新创建DB Link

SQL>create database link P605_DB
  connect to DBLINKUSR identified by test
  using 'np605_db';

SQL> select db_link from dba_db_links;

DB_LINK
--------------------------------------------------
P605_DB
看到了吧,没有那串长长的尾巴了,呵呵！
