Infrastructure Software

I need help in indentifying the memory utilization collected after executing ps -aux command at the prompt.

When I execute ps -aux a whole list of running processes are listed and I am interested at the %CPU and %MEM column for each processes. Is these the columns that list the % of memory and CPU utilization by the processes? I presume it is?

Lets examine the output of the ps -aux command I executed at a Database Server running Oracle and Oracle Application Server. May I know the %MEM will be calculated based on what? When I calculate by adding the %MEM for all the process listed, the addition will be more than 100%? So how would I know how much physical memory was taken by a process based on the %MEM column?

Please advise... Thank you.

I attached the output of the ps -aux command below;
