I could have sworn that only Oracle on Windows uses a true multi-threaded architecture. That Oracle on Unix and Linux uses a multi-process architecture. And that if you ps -ef | grep <ORACLE_SID here>, you will see each of the processes listed.

But you might be talking about something else entirely, I guess.
