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

唉，还有这么多人在走Oracle DBA这条路，此路太窄，职位少，要求极高，特别是现在，要有5年以上加拿大工作经验，英语又要好，几乎所有人都可望不可及。现在形势下，找到Oracle DBA的职位，恐怕不是很实际。我的几个多伦多的朋友(在Oracle论坛上认识的)都有Oracle OCP证书，有两个跟我一样还有Solaris的SCSA证书，有的是被Layoff的Oracle developer， 都在彷惶，所以建议朋友们从现在的实际着手，从容易得到的低职位着手，第一步是找到工作，而不是找到高职位工作，免得耽误了时间，我来多市已经接近一年了，仍无工作。我认为没上这条船的朋友应该慎重。此话与朋友们共勉。

他有14年DBA经验，当过Oracle, DB2 SQL Server等多种数据库管理员。会编程，懂操作系统，好象是俄国人，还会德语。我一看公司对他的介绍，第一个感觉就是大陆新移民中几乎没有人达到这样的水平。

DBA职位少，在现在的就业形式下要求特别高。这个职位有公司内部的人应聘都没成功，从外边招来个高手。前几天Remedy出了问题，这个DBA重建并恢复了数据库。这样的职位责任很大，新手难以胜任。
