Question

我的计算机上有两个数据库：orcl和orcl1。

我从orcl1创建了以下数据库链接：

create public database link remote_connect
connect to system identified by ***
using 'orcl';

然后我运行以下查询：

SQL> select * from test@remote_connect;
select * from test@remote_connect
                   *
ERROR at line 1:
ORA-01017: invalid username/password; logon denied
ORA-02063: preceding line from REMOTE_CONNECT

我已经确保用户名和密码正确无误，因为我使用它们来登录orcl。有什么问题，我该怎么解决？

编辑：

我的tnsnames.ora文件在orcl1目录中如下所示：

ORCL1 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1522))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl1)
    )
  )

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1522))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl1)
    )
  )

我的tnsnames.ora文件在orcl目录下看起来像这样：

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

ORCL1 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

您可能会发现，使用简单连接语法比使用TNS别名更简单，因为使用它们似乎使您不清楚实际上要连接到哪个数据库。

您可以执行以下操作：

create public database link remote_connect
connect to system identified by ***
using '//localhost:1521/orcl';

数据库链接-无效的用户名/密码
