oracle——监听（一、多实例监听配置）

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：

      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.152.131)(PORT = 1521))
    )
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
    )
  )

      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.152.131)(PORT = 1523))
    )

    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = NHL)
    )
  )
ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.152.131)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )
TEST =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.152.131)(PORT = 1523))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = test)
    )
  )

改完配置并启动。

这个还有个缺陷，listener中的ORACLE_HOME没写，自己配置的时候记得写上
