This doesn’t even go into the risks for MySQL, under Oracle.
Java doesn’t threaten Oracle’s primary revenue stream, MySQL does.
Right. Oracle kills MySQL and acquires a hardware/server division. Java is incidental.
Moving mySQL does gore my ox. mySQL is all the database I need for most work. I've used Oracle for many commercial applications. There is one thing certain about installing Oracle on a server. If it was fast before Oracle arrived, it will run like a wounded dog once Oracle is installed. It's best to put Oracle on a dedicated server where it isn't destroying the performance of everything else on the server. As a database, it works fine. It's just more expensive than I can justify for research projects with zero revenue. I have very good results using python or C++ library packages to hook my applications to a mySQL database. Hopefully, I won't have to go shopping for an alternative.
