Oracle lsnrctl--監聽器的啓動和關閉

在啓動、關閉或者重啓oracle監聽器以前確保使用lsnrctl status命令檢查oracle監聽器的狀態：

一、$lsnrctl status：檢查當前監聽器的狀態

二、$lsnrctl start [listener-name] 啓動全部的監聽器,能夠指定名字來啓動特定的監聽器

三、$lsnrctl stop [listener-name]  關閉全部的監聽器，能夠指定名字來關閉特定的監聽器

四、$lsnrctl reload  重啓監聽器，此命令能夠代替lsnrctl stop,lsnrctl start

五、lsnrctl hep      能夠顯示全部可用的監聽器命令

經常使用命令參數：

stop - Stop the Oracle listener
status - Display the current status of the Oracle listener
