Re: Memory usage of Oracle processes

I'm not a UNIX system admin. But I believe you have to use ipcs -b (on Solaris) to find out the shared memory size and subtract that from what you see in top. The reason is Oracle processes share memory. You can't simply add them up and say that's all Oracle takes.

Also make sure you're looking at resident size (RES in top), not virtual size (SIZE). I don't think shared memory can go virtual. Correct me if I'm wrong.
