需要为第二个NIC添加Oracle侦听器

问题描述

我当前在Windows 2012环境中运行Oracle 11g.

I am currently running Oracle 11g on a Windows 2012 Environment.

我最近添加了另一个NIC以进行故障转移，但是我不确定如何处理我的listener.ora文件和tnsnames.ora文件.有人可以提供指导吗?作为参考，我正在使用的当前IP为192.168.0.52，我要添加的第二个NIC的IP为192.168.0.53.

I recently added another NIC to allow for failover, however I am not sure as to what to do with my listener.ora file and my tnsnames.ora file. Could someone offer guidance? For reference, the current IP I am using is 192.168.0.52 and the IP of the second NIC that I would like to add has the IP of 192.168.0.53.

下面是我的listener.ora文件:

Below is my listener.ora file:

# listener.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:\app\Administrator\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.52)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = D:\app\Administrator

下面是我的tnsnames.ora文件:

Below is my tnsnames.ora file:

# tnsnames.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

LISTENER_ORCL =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.52)(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 = 192.168.0.52)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

感谢您的所有帮助！

推荐答案

好，您可以在listener.ora中指定多个ADDRESS条目:

Well, you can specify multiple ADDRESS entries in the listener.ora:

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.52)(PORT = 1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.53)(PORT = 1521))
    )
  )

在tnsnames.ora中:

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.52)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.53)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

当我为侦听器指定多个地址时，它将在列出的所有接口上侦听.当tnsnames中的至少一个地址可以连接时-它就连接了.我有11g可用于在客户端和服务器端进行测试.我检查了文档( tnsnames.ora中有多个地址列表)，并指出可以在tnsnames.ora中明确指定参数(FAILOVER=on).

When I specify multiple addresses for listener, it listens on all interfaces listed. And when at least one address in tnsnames can be connected to -- it connects. I have 11g available for testing both on the client-side and on the server-side. I checked the documentation (Multiple Address Lists in tnsnames.ora) and it states that parameter (FAILOVER=on) can be specified in tnsnames.ora explicitly.
