Question : instance_resources

Does an oracle instance consume a lot of resources?

We have a staging/QA database on a production machine that has 1/2 G RAM allocated to it.
We do no use it every day. Some admin sugested they shut it down and start it whenever testing is needed so they save on resources.

I do not like the idea. If we are not using it then CPU consumtion is ZERO and RAM may not not be really used. Is this correct. leaving it on should be much better for testing as the caches are not reset too.
