I also can not access my CertView (three attempts)
Specifically, what do you mean by this?
Have you ever been able to log in to your Certview account? If not, did you create one? The accounts do not get created automatically.
If you have logged into the account before, then what happens when you try to log in now?
Create a Service Request (SR) on http://education.oracle.com/pls/eval-eddap-dcd/OU_SUPPORT_OCP.home?p_source=OCP
I am also having problems with authenticating on Certview and am waiting for a response to my SR.
