From SID to connected machine

Hello,

I'm looking to trace a sid from oracle to a pid on unix to a connection/socket/port to another machine.  Server is Sun Solaris 2.8.

I'm trying to deimplement a userid and there is a connect string to it buried somewhere on one or more of eight different application machines.  The engineers have looked for the connection, but are unable to find it.  I need to tell them which machine it's coming from.  If anyone has the steps to do this, I'd appreciate a note back.  I've tried to match the pid to the lots of logs, but cannot find a match. 

Thank you very much.  Any information or referral to documentation is appreciated.

The userid connection on topsessions:

PALMAPP     SID 149
PALMAPP     SID  58
PALMAPP     SID 129
PALMAPP     SID 204
PALMAPP     SID 158

The netstat output.  I believe the connection is coming from either va8 or va11.
