Very detailed and useful explanation. Thanks

By Kamil Kazanecki on 1/25/2026

Well explained and prepared. Unfortunately, the 11g and 12c databases on Oracle Linux 5 don't work properly. Numerous errors and conflicts pop up during installation. The software is significantly outdated. It's still possible to install the system and Oracle DB 12g, but when upgrading to 12c, the system starts throwing errors. Despite numerous attempts and support, the system couldn't be upgraded and I ended up having to rebuild Linux and the 11g database.
