Question

我已经整天尝试使用网络上建议的解决方案解决此问题，但这些解决方案都没有奏效。

我正在尝试在我的PC上设置Oracle数据库以进行远程连接。它适用于本地连接，但我试图让它适用于所有连接。

我的连接字符串是：

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = F:\Programs\Oracle\oracledatabasexe\app\oracle\product\11.2.0\server)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = F:\Programs\Oracle\oracledatabasexe\app\oracle\product\11.2.0\server)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))
    )
  )

DEFAULT_SERVICE_LISTENER = (XE)

我的听众已启动，其内容为：

我使用的是Oracle Database Express Edition 11g。

我尝试从数据库服务器所在的同一台PC连接，并从另一台PC连接，但是在同一网络上。我得到了＆＃34; TNS：没有听众＆＃34;两台计算机上的错误。

得到一些帮助会非常好，因为我现在有点绝望了。

编辑：这是我获得的lsnrctl status命令：

Sub ColorMeBlue()

    Dim iStart, iEnd As Long
    Dim i As Integer
    Dim b As Boolean
    iStart = 1: iEnd = 10

    b = False

    '~~> We will set b to true if all cells in A1:A10 conatins 100
    For i = iStart To iEnd
        If Cells(i, 1) = 100 Then
            b = True
        End If
    Next

    '~~> We will paint Blue if b is true
    If b Then
        Rows("1:10").Interior.Color = vbBlue
    End If

End Sub

非常感谢！

您是否检查了听众状态？本地连接不使用侦听器来连接数据库。但远程使用它。使用 lsnrctl status 检查它。如果获取TNS：没有听众使用 lsnrctl start 来启动它。

＆＃34; ORA-12541：TNS：没有倾听者＆＃34;
