本文发表在 rolia.net 枫下论坛I passed them and got certification in several months last year without any training or even buying any books. Instead, I just did research on internet and borrow some reference materials from friends.

I do not feel it difficult especailly when you have experience, but it is boring, and you may need put lots time on it(for memorizing lots of stuff). I almost could not insist to the end because I was extemely busy from time to time.

I don't think it will help much than experience, but it may be good for getting more oppotunities. Frankly, most of the DBAs I have met don't have the certification, but as a unix admin, I have one, sounds like a joke. If you hope to get a job soon by having certification, it may disapoint you. At leat for me, it doesn't help that much. Anyway, they are just exams, you can pass them if you put enogh time on it, but experience is the most important thing. Certification itself is barely better than nothing, but you can learn the whole picture of this technology by preparing those exams. Good luck for whatever you would like to do.更多精彩文章及讨论，请光临枫下论坛 rolia.net
