oracle - 能够通过 localhost 而不是通过 IP 地址访问 Oracle 数据库

Question

我已经安装了 Oracle 11g，出于测试目的，我使用编辑器(称为 DBeaver)连接到数据库。 当主机名提供为 localhost 时，它会连接。但是当主机名提供为系统的 IP 时，编辑器无法连接并显示以下消息。

IO Error: The Network Adapter could not establish the connection
  The Network Adapter could not establish the connection
    java.net.ConnectException: Connection refused: connect

我已经尝试从

更改 listener.ora

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
  )

到

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.140.0.3)(PORT = 1521))
    )
  )

在这里，我将 localhost 替换为 IP，即 10.140.0.3。 但至今无法连接。 有人可以分享一下这方面的经验吗？

Answer 1

您的 listener.ora 条目不正确。应该如下所示。

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.140.0.3)(PORT = 1521))
    )
  )

为避免与手动编辑相关的错误，请使用网络管理器并从那里添加地址。 检查以下屏幕截图以进行 listener.ora 文件相关的更改。

Open Oracle Net Manager

Add IP address to the Listener

更改完成后，不要忘记从 Oracle Net Manager 中保存!
