Posted on October 25, 2023 by Mike.Dietrich Operating System Oracle Database 19c 51

I know, many of you were asking several times already about the certification of the Oracle Database on Oracle Linux 9 and Red Hat Enterprise Linux 9.

This may become a longer blog post. One of the customers I work with for many years contacted me a few weeks ago.
