Can't find missing packages Oracle Linux 8

super newbie here. Trying to learn DBA stuff. I've been trying to install oracle database 18c on Oracle Linux 8 but there are two missing packages that are just not being found. I need these to complete the installation properly: nothing provides compat-libcap1 needed by oracle-database-preinstall-18c-1.0-1.el7.x86_64 - nothing provides compat-libstdc++-33 needed by oracle-database-preinstall-18c-1.0-1.el7.x86_64 These two commands do not work.

-none
rpm -ivh compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm

-none
rpm -ivh compat-libcap1-1.10-7.el7.x86_64.rpm

I've looked a lot online. Thanks in advance.
