Sometimes the experience you have is not enough to get a better job or to move on, if you are competing with others DBAs with the same time of experience that you, I'm 100% sure that if they had any kind of certification, they will be 1 step ahead of you to get that position. The market prefers "Certified" professionals. I agree with everybody, the certification at OCA, OCP,OCE level is a joke, it's so easy to get it, but is a true. I saw so many excellent candidates lose excellent opportunities only because they don't have any certification.What I think, if you are a genuine DBA then you should not be bothering much >> about expensive courses & certifications, your hands on experience &
knowledge will take you to the heaven you deserve though you will not be titled >> like OCM, OCP etc by Oracle.
Better still, how about some verifiable credentials?I'll have to start claiming the equivalent of about 75 years experience with Oracle.
As far as you go, who knows? You seem embarassed about your training and experience, why else would you hide it?Thanks for reminding us that time spent and experience gained aren't necessarily the same thing.

Yes, and while I removed it (so as not to get n00bs in over their heads), the first statement remains as great advice for senior DBA's, my primary audience.your advice contradicts itself and simply makes no sense.
Yup, the docs suck. What else is new?Not only is it not "well documented", it's actually not documented within the Oracle docs at all !!
Real-world experience, and lots of sound empirical evidence from my clients.how can you make such a claim ???
If I said "black is black", you would no doubt argueHi Don
that "black is white".
Yes, and while I removed it (so as not to get n00bsOK, so you're saying that the first thing an "experienced" DBA should do is migrate all the indexes into a large block size because for most databases, it's not going to make a measurable difference and must be evaluated carefully on a case by case basis !!

OK, so when you say the benefits are well documented, even in the Oracle Docs, you're actually referring to the Oracle docs that suck because they don't actually document what they're supposed to well document !!actually not documented within the Oracle docs at allNot only is it not "well documented", it's
