How to trace a oracle "apps" user in R12.1.3 back to the local userid that launched a process/conc

I have a problem UNIX process that was created by a local user who logged in to the application as john. When he lauches a process within R12, he shows up as apps.

all users show up as apps. Is there a way to trace a UNIX PID back to john so that I will know who is causing the problem? see sample UNIX PIDS below.
