How to find out if Spectrum 9 supports Oracle 12c

Product Feature: Installation / Upgrade
According to the product manager as long as it has a jdbc driver, we should be able to support it.
So you will need to check with Oracle if there is a jdbc driver available and test it with Spectrum.

Unfortunately we do not have test or plans to provide you but you can contact one of our consultants, maybe they developed something.
