The detailed certification information that used to be available on the Sybase web site is not currently externally accessible since SAP decommissioned the site - all that is currently available is the basic information in the SAP Product Availability Matrix (PAM) and the base release information available in the ASE documentation.
ASE support is looking into ways of restoring external access to the certification reports, possibly here as SCN documents or on the SCN wiki. I don't have any estimate for when this will be available, though.
If you have a support contract, you can open an incident to ask about specific versions/platforms; we still have internal access to the reports. If the support engineer doesn't know how to access the reports, ask them to get in touch with me.
