Download the 'oracle-database-xe-18c-1.0-1.x8664.rpm' RPM file from the Express Edition (XE) download page here. With the RPM file downloaded, you can install the Oracle prerequisites and software using the following command as the 'root' user. It automatically pulls down all dependencies, including the 'oracle-database-preinstall-18c' package.

Make a copy of settings.env.sample, e.g. Mysettings.env, and modify as desired. Package oracle-xe-11.2.0-1.0.x8664 is intended for a different operating system To fix this is fairly easy. Open the Dockerfile.xe, go to line 61 (as of this writing) and change this code.

Oracle 18c can now be installed on Oracle Linux using an RPM. This article describes the RPM installation of Oracle Database 18c 64-bit on Oracle Linux 6 (OL6) and 7 (OL7) 64-bit. The article is based on a server installation with a minimum of 2G swap and secure Linux set to permissive. An example of this type of Linux installation can be seen here (OL6 or OL7).
- Oracle Installation
The '/etc/hosts' file must contain a fully qualified name for the server.
Set the correct hostname in the '/etc/hostname' file.
If you have a ULN subscription, the documentation suggests you can just install it using the following command as the 'root' user. I don't have a ULN subscription, so I can't confirm this.
If you don't have a ULN subscription, you will have to download the 'oracle-database-ee-18c-1.0-1.x86_64.rpm' separately from the Oracle 18c (18.3) download page here.
With the RPM file downloaded, you can install the Oracle prerequisites and software using the following command as the 'root' user. It automatically pulls down all dependencies, including the 'oracle-database-preinstall-18c' package. If you do this the 'oracle' user doesn't have a home directory created, so I install the preinstall package first, so the 'oracle' user is as I expect it. The additional command is included below, but commented out.
On RHEL you will need to manually get the prerequisites RPM from the Yum repository and run it manually before installing the database RPM.
ORACLE_HOME for the software installation is '/opt/oracle/product/18c/dbhome_1'.
In addition to the software installation, the RPM creates a script that allows you to create a demo database called 'ORCLCDB', with a pluggable database (PDB) called 'ORCLPDB1'.
You can of course create a database in the normal way, using the Database Configuration Assistant (DBCA). You don't have to use this script.
Here are some thoughts about this method of installation.
- The mechanism is designed for a software-only installation of the Oracle database software. It is not a single command to get Oracle running. As a result it doesn't feel particularly simpler than doing a regular silent installation of the database software, but people with less experience may disagree.
- The RPM can only be used to install the software, not update it. This is a 'one-shot' solution.
- You have no control of the software installation itself. If you have a corporate standard you use for your installations, this is not the solution for you. Remember, the
ORACLE_HOMEfor the software installation is '/opt/oracle/product/18c/dbhome_1'.
- Even with a ULN subscription, it is unlikely you would want to pull this software down for each installation. You would need to create a local Yum repository to host it.
- It's an interesting exercise, but I would not consider using this approach for anything other than demos at this time.
If you want to see it in action, you might want to try this Vagrant build here.
