oracle processes with SOCKT in glance command....reason?

Hi Friends,

I could see following oracle process in the glance command. i see nothing running in the database although. I tried google it but no success. Another team ,which needs all the processes on the server is complaining. Can someone help me what exactly are these sessions/ how to find out the original place where these are emerging ?

Sockets used between different oracle servers (daemons).
If you are sure you have no more oracle running, then do an

# ipcs -a 

If you see anything oracle still, then you have rubbish to be removed manually, look at ipcrm man pages
