I am also not able to access my account. But on home page they had given instruction as:
Certification records for Java, Solaris (Cluster), Oracle Solaris (Cluster), MySQL, NetBeans and OpenOffice.org are no longer available through Integral7. Certification history will be available in Oracle's CertView tool in late June/early July. When these certification records are available in CertView, an announcement will be made on Oracle's Certification Blog . Please subscribe to this blog to stay up-to-date on what's going on in the Oracle Certification Program.
so at the end of month or start of july issue will be resolved.
