Is it possible to hide process args from 'ps -ef'??

[Helge Egelund Rasmussen]

It is possible to give Oracle programs the username/password on the 
command line, ie : 
    $ sqlplus scott/tiger

This is all very nice, BUT when another user execute 'ps -ef' he/she 
can see the password!

Is it possible to hide the arguments, so that they won't show up in
the 'ps' output (possibly by 'exec'ing sqlplus in some devious way :-)??

I know that Oracle will ask for the username & password if these aren't given
as arguments, but I would prefer giving them as arguments.

Btw. I'm using SysV3 (Interactive Unix).
