Download Software

Download the Oracle software from OTN or MOS depending on your support status.
2

Unpack Files

Unzip the file. You should now have a single directory called "database" containing installation files.

Code/Command (click line numbers to comment):

1
unzip linuxx64_12201_database.zip
3

Hosts File

The "/etc/hosts" file must contain a fully qualified name for the server. For example. Set the correct hostname in the "/etc/hostname" file.

Set Kernel Parameters

Add the following lines to the "/etc/sysctl.conf" file, or in a file called "/etc/sysctl.d/98-oracle.conf". Run one of the following commands to change the current kernel parameters, depending on which file you edited. Add the following lines to a file called "/etc/security/limits.d/oracle-database-server-12cR2-preinstall.conf" file. Set SELinux to permissive by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows. The server will need a reboot for the change to take effect.

Setup

Before we consider the packages required by the Oracle installation, it's probably worth making sure some basic package groups are installed. If you have installed the suggested package groups, the majority of the necessary packages will already be installed. The following packages are listed as required, including the 32-bit version of some of the packages. Many of the packages should be installed already. Create the new groups and users. We are not going to use the extra groups, but include them if you do plan on using them. Create the directories in which the Oracle software will be installed. Putting mount points directly under root without mounting separate disks to them is typically a bad idea. It's done here for simplicity, but for a real installation "/" storage should be reserved for the OS. If you are using X Emulation, login as root and issue the following command. Edit the "/etc/redhat-release" file replacing the current release information "Fedora release 26 (Twenty Six)" with the following. Login as the oracle user and add the following lines at the end of the "/home/oracle/.bash_profile" file.

Installation

Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable. Perform a software-only installation either using interactive mode (GUI) or silent mode. Clean up some library stubs and relink the software. Thanks to Andy Campbell for telling me about this solution.

Database Creation

You should now be able to create a database in the normal way using the DBCA in interactive (GUI) or silent mode. Here is the silent mode database creation I used. You should now have a functioning database.

Post Installation

Edit the "/etc/redhat-release" file restoring the original release information. Edit the "/etc/oratab" file setting the restart flag for each instance to 'Y'. For more information see: Hope this helps. Regards Tim...
