is 19c SE2 support RAC One on ORACLELinux Version??
We Found this article as below attached file
From 19c Oracle RAC is not available with Oracle SE2 - however if you have an Oracle Linux support contract in place you can
use Oracle Clusterware for free and create an Active / Passive cluster on which you can run 19c at one node with the option to
fail-over to the second node.
