Re: memory
The following will help you track down memory hogs on a system if for some reason you down have top of if you've run out of forks and you need to exec a command, etc, etc.
This is a ps command with user defined outputs, I've just put memory size as the first column, then the process ID, the parent ID, the amount of CPU its using, the command name and its arguments. The w wraps the output. Then just sort.
ps -ewo "size pid ppid %cpu command args"|sort -n
You can redefine the output in pretty much any way you need depending on what you are tracking down.

Re: memory
one important thing about Oracle performance is the configuration of SGA. You must verify if your SGA is enougth, mostly the buffer cache parameter, to permit about 90 to 95 percent of readings in memory (read hits). You may use statspack to see if it's ok.
Here you have a good document to guide you :
