The following mind map highlights the key steps to install Oracle Database 19.24 on Oracle Linux 9.4

Please note that installation of Oracle database 19.3 on Oracle Linux 9.4 is a little bit different.
As the base release 19.3 is a little-bit old compared to Oracle Linux 9.4, then we have to apply the release update patch 19.4 (patch 36582781) with the base-release 19.3 in one-go using the following command:
$ export CV_ASSUME_DISTID=RHEL8
$ ./runInstaller -applyRU /stage/36582781
This is a must as per the installation guide. Otherwise, if you tried to install only the 19.3 base release on OL 9.4, you will get the following error and the installation will not proceed:

We may have another detailed post about the above error shortly.
