and get certified. I've been hauling an Oracle cert book around since version 7 but haven't bothered writing the exams. There are a few reasons why I haven't, one of which probably wouldn't be a good idea to talk about on a public blog. Another is i've worked with quite a few DBA's over my career... The vast majority of OCP's that I have worked with had below average technical skills. The vast majority of great DBA's that I have worked with have not been certified. (Of course there are exceptions to both statements.)
So why am I doing it now? Work is pretty slow at the moment and will be for the foreseeable future... So instead of going stir crazy in my cubicle its something to keep me busy. Its a good way to review all the features of Oracle and this is where I see the real value of an OCP.
