How can i see if a unix Process Aplication i.e oracle is running in parallel

There is a unix process process in oracle running and i see running by typing ps -fea|grep GE_CLIENTES.

The question is How can i see if this process is running in paralel. I dont know with a Unix command or specifically its a comand from Oracle.

I kow a Parallel process ia a process that oracle use to run in varius CPUs to run faster, i mean this process uses different resources to run this job.

I apprecite your help

i) if you have more than one processor the system will automatically distribute your processes among them. If there are many "cpu intensive threads" (normally waiting and doing nothing) you are fine. Consult oracle manual about which process "does the big compute". (I have no oracle knowledge, but "grep GE_CLIENTES" does not sound like a *server* process)
ii) Test it: simply run some compute-intensive database application/benchmark and see whether your systems cpus get used
