Re: Installing Oracle 19c (19.7) on Oracle Linux 8.2......

Thanks for your reply, Mladen.

In terms of OL8 improvements, that's good to know. As far as NVME goes, I'm on AWS, and the newer nutro-based instance types do, in fact, use NVME, so that's good for me.

Honestly, I really rarely have a chance to upgrade (we still have one OEL5/11.2 DB system), so I wanted to try to get as up to date as possibe with all this.
