Does Oracle lock (pins) RAM ?

My DBA doesn't know and Oracle says they don't use plock(), however installation of 7.3.3.4
requires MLOCK privilege for dba group (HP-UX) This must mean that Oracle pins code or data in
physical memory for shared or regular memory, and if so my question is how much? Is there a way to figure out RAM requirements for Oracle. If it uses only virtual memory, RAM needs will depend on system load (TPM), but if it pins memory it's another matter.
