I received my OCA certification at June 2006. At that time, as you know, the institute responsible for the oracle certification was Prometric. Right now they gave the job to Pearsonvue.
Oracle has a pretty neat website that can show you your certification/exam history which is called certview.oracle.com. Two weeks ago, I logged on the website and surprise…. I cannot see my OCA certification there. After struggling a couple of days what to do. I emailed the OCP team. They told me I had to submit the web form at http://education.oracle.com/pls/eval-eddap-dcd/OU_SUPPORT_OCP.home?p_source=OCP .
After two days I got an email from them. It says that the issue is fixed and now on certview.
If you have such issues believe me they are really helpful and quick.
So don’t worry. Don’t panic : )
