    启动监听使用lsnrctl start就可以了

    如下:

    oracle@rtest ~]$ lsnrctl start

    Listening Endpoints Summary...
      (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=rtest.localdomain)(PORT=1521)))
    The listener supports no services
    The command completed successfully
     

    使用监听程序控制实用程序可控制监听程序。使用lsnrctl,可以:
    • 启动监听程序
    • 停止监听程序
    • 检查监听程序的状态
    • 根据配置文件参数重新初始化监听程序
    • 动态配置多个监听程序
    • 更改监听程序口令
    该实用程序的基本命令语法为:
    LSNRCTL> command [listener_name]
    发出lsnrctl命令时,如果没有指定其它监听程序名称或执行SET CURRENT_LISTENER命令,此命令将作用于默认的监听程序(名为LISTENER)。如果监听程序名为LISTENER,则可省略listener_name参数。
