本文详细解析了Oracle数据库中监听器的三种配置方式：单一监听器处理多实例、单一监听器通过不同端口处理多实例、以及多个监听器分别处理不同实例的方法。深入探讨了listener.ora与tnsnames.ora文件的配置细节。

三种情况：

1、一个监听在一个IP一个端口上监听多个实例

2、一个监听在一个IP不同端口上监听多个实例

3、多个监听监听多个实例

情况1：

listener.ora文件：

# listener.ora Network Configuration File: E:\app\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_ORCL =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = ORCL)
      (SID_NAME = ORCL)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = NHL)
      (SID_NAME = NHL)
    )
  )

    )
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
    )
  )

tnsnames.ora文件：

    (CONNECT_DATA =

      (SERVICE_NAME = orcl)
    )
  )

    )

    (CONNECT_DATA =

      (SERVICE_NAME = test)
    )
  )

改完配置并启动。
