   Oracle环境:oracle 10.2.0.1 创建的 public dblink 连接oracle 11.2.0.3

  ORA-01017: invalid username/password; logon denied ORA-02063: preceding line from

  一.创建dblink

  create public database link dmz63

  connect to xyy identified by xyy

  using '(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = 10.0.0.1)(HOST = 192.xxx.xxx.xxx)(PORT = 2261)))(CONNECT_DATA = (SERVICE_NAME = xyy)))';

  二.创建dblink 后使用时提示如下错误:

  select * from dual@dmz63

  报错如下:

  ORA-01017: invalid username/password; logon denied

  ORA-02063: preceding line from

  三、问题分析:

  根据ORA-01017的提示是连接到另一方的用户密码错误,于是直接使用配置的用户密码(lsxy/lsxy)登录数据库发现正常登录,进一步的查看建立好后的dblink 语句,其中用户名都转化为了大写,由此猜测密码是否也被转化为了大写从而导致密码错误。

  根据猜测百度了下,确实有这种情况。当9i或10g的版本的Oracle数据库连接11g的版本时,会自动将密码转化为大写。

  四、解决办法:

  我们将dblink 的创建语句稍微改写即可,,如下:

  将密码用双引号引起来

  create public database link dmz63

  connect to xyy identified by "xyy"

  using '(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = 10.0.0.1)(PORT = 2261)))(CONNECT_DATA = (SERVICE_NAME = xyy))';
