When I install the database using the rpm it seems to be EE (Enterprise Edition) only,
I can't find a way to install SE2 with the rpm, I guess it's not just a licensing issue?
This page https://www.oracle.com/database/technologies/oracle-database-software-downloads.html
says: 21.3 - Enterprise Edition (also includes Standard Edition 2)
But another page https://docs.oracle.com/en/database/oracle/oracle-database/21/ladbi/restrictions-for-rpm-based-installations.html#GUID-22C1C4C1-49BE-4664-9A73-E96F70665633
says: An RPM-based Oracle Database installation is not available for Standard Edition 2.
