为什么出现此错误：“状态：失败-测试失败：ORA-01017：无效的用户名/密码；登录被拒绝”？

Question

我正在尝试使用Oracle Database 11g创建一个简单的分布式数据库。我已经创建了2个虚拟机，既是Windows 7，也为所有人设置了静态ip，然后修改了[[listener.ora。例如，第一个VM的listener.ora如下所示：

我已经通过ping从PC上检查了一下，看看是否能收到回复并且它可以正常工作。然后，我从PC修改了

tnsnames.ora

，如下所示：

LISTENER_ORCL =
  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))


ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

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

SERVER1 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.75.131)(PORT = 1521))
    (CONNECT_DATA =
      (SID = XE)
    )
  )

SERVER2 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.75.130)(PORT = 1521))
    (CONNECT_DATA =
      (SID = XE)
    )
  )

当我尝试使用主机名创建连接：
192.168.75.131

（第一个VM）时，出现以下错误：状态：失败-测试失败：ORA-01017：无效的用户名/密码；登录被拒绝。用户名和密码正确。

Answer 1

尝试使用Server1上的sqlplus连接-devops方式-可重复

C:\>set LOCAL=192.168.75.131/XE
C:\>sqlplus system/system_password
SQL>connect admin/admin_password

您也可以尝试：
C:\>set LOCAL=localhost/XE
C:\>sqlplus system/system_password
SQL>connect admin/admin_password

祝你好运！
