大家好，我是讯享网，很高兴认识大家。
Oracle的默认监听端口是1521，有没有方法查看主机中都有哪些程序打开了这个端口，答案是肯定的，lsof这个常用命令就能顺利的帮上忙。
lsof并不仅限于查看打开文件的进程信息，更多的命令参考可以参考联机手册“man lsof”。
1.罗列一下在这个命令的输出信息

2.命令参数解释
lsof -i tcp:1521
这里的tcp也可以替换为udp，可以根据具体的协议的不同查看。
3.小结
问题驱动型处理方法——就是自己给自己设定诸多的问题，然后通过实践和尝试逐一处理和解决。这样对处理问题能的提高是有帮助的。
希望这样的方法对大家有帮助。
Good luck.
