How to identify process id for a server (for example, Oracle Service Bus) that is listening on port number, say 8090

Young WebLogic/JBoss application server administrators in my company have asked me one question on several occasions - "There are several Java processes running in the Unix server. How do I identify the process id of an application server (for example, Oracle Service Bus) listening on port number 8090". I thought this tip may be required by many others in other parts of the world and hence this post.

In Linux:
It is little straight forward to find out the process id by using the following command.


[portalmid@SVRCBS59 ~]$ netstat -anp | grep 8090
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)

[portalmid@SVRCBS59 ~]$

Needless to explain, the process id is 21962.


In Solaris:
The above command does not work as such. I will write another post with example. Please wait for further update on this.
