    What does the Oracle documentation say? What do all the articles that a search on Google throws up say? If you've read the documentation & there's a specific part that you don't understand then feel free to ask, but please at least try reading the documentation first before posting on here - all you'll get is a link to what you ushould have read in the first place.
