I had installed Oracle 12c database on Oracle Enterprise Linux 7 yesterday. I am sharing my steps which I had taken for installation. Hope you find this helpful.
Step 1: Download the OEL7 ISO for 64 bit from Oracle Edelivery (V46135-01.iso and V46138-01.iso)
Step 2: Open Virtual Box and Create New Virtual Machine choosing the OS option as Other Linux -> Oracle 64-bit.
Step 3: Point the CD/DVD to the ISO image downloaded from Edelivery site
Step 4: Change the boot sequence to CD/DVD, Hard Disk
Step 5: Create a shared folder with auto mount and read only option and point it to the setup location on the host machine.
Step 6: Start the Virtual Machine and follow the steps.
Step 7: Install Additional Guest Image – This will enable to access the shared folder on host machine.
Step 8: Install the RPM mentioned in the appendix section of this article.
Step 9: Copy the Oracle 12c database setup from the shared folder on host to the /u01 directory.
