Hello to all of you,
Please excuse some of my questions even though they might sound stupid to some of you seasoned professionals. I am only a student and still learning and I would like to have a clear understanding of the answers to these questions before I start practising as a DBA:

Question 1: Is METALINK the same as contacting Oracle support but METALINK is through the web and Oracle support is through the phone?

I am only a student but I will like to know the difference between the two before I start practising as a DBA.

QUESTION 2: So as a DBA when do you have to use or contact these 2(METALINK and ORACLE SUPPORT)

Please give me very clear answers with example if you can.

thanks
