It's not that we don't want to help you but.... I'm going to say it cause it needs to be said.
1. By asking us what kind of configuration you should implement means you haven't done any research yourself.
2. By stating that you're using old and soon to be unsupported Oracle software with the excuse of "because management doesn't want to buy it" says that you obviously haven't read your license agreement.
So here's my advice.
1. Go read
2. If your management finds out that your not doing your job (see #1)smile when you ask "would you like a biscuit with that?"
We are all about helping people whom have banged their heads against the wall looking for answers but can't find it. We're not about helping people who won't help themselfs.
BTW: what company do you work for?
Oracle it's not just a database it's a lifestyle!
