Few months ago I posted the invaluable of OCP...Most company dont need it.I hope Oracle will not be the same as MSCE professionally.Oracle makes it's 9i more valuable by requiring a certified course for all future candidates...I am going to get upgrade soon...tell me what that break down % on 9i please??
Oracle don't print a breakdown on the exam report like they used to so no-one can give you an official breakdown. I didn't pay too much attention the question breakdown but I would say the number of questions was pretty equal throughout the exam checklist, with the exception of RAC and Advanced Replication which got very few questions.
Someone out there may have paid more attention to the breakdown. If so they may be able to give you as rough idea.
