It's not that simple. Oracle in particular uses lots and lots of shared memory. A good amount for each process is likely to be the same memory, shared between all of them -- just making a blind total will greatly inflate it. I've heard people suggest querying Oracle itself about how much memory its using, though I'm not too clear on how.

VSZ shows claimed/reserved/overcommitted memory.
RSS shows resident/initialized memory.

Usually RSS and pmem are more relevant. Check yourself.
Code:
ps -u myuser -o pid,vsz,rss,pmem,args

Follow the automatic content links below! Search this forum for RSS and VSZ!
For a quick summary, and comparison with your ps results try
Code:
prstat -t
