We are upgrading CA API Gateway from version 9.2 to 9.3. So far we have been using the embedded database. With this upgrade we are looking into moving to an external database. I have been looking into the documentation for possible databases CA API Gateway supports. So far what I have seen is only MySQL. Does CA API Gateway support other databases? More importantly does it support Oracle 11/12 databases as this would be our preferred DB? I am asking about the database type of the Gateway and not about databases we can access using JDBC in policy assertions.
