Oracle Database 19c RPM Installation On Oracle Linux 7 (OL7) and Oracle Linux 8 (OL8)
Oracle 19c can be installed on Oracle Linux using an RPM. This article describes the RPM installation of Oracle Database 19c 64-bit on Oracle Linux 7 (OL7) 64-bit or Oracle Linux 8 (OL8) 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 (OL7 or OL8).

Hosts File
The "/etc/hosts" file must contain a fully qualified name for the server.
<IP-address> <fully-qualified-machine-name> <machine-name>
For example.
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 192.168.56.107 ol7-19.localdomain ol7-19
Set the correct hostname in the "/etc/hostname" file.
ol7-19.localdomain
Oracle Installation
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.
yum -y install oracle-database-ee-19c
If you don't have a ULN subscription, you will have to download the "oracle-database-ee-19c-1.0-1.x86_64.rpm" separately from the Oracle 19c (19.3) 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-19c" 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.
#yum install -y oracle-database-preinstall-19c yum -y localinstall oracle-database-ee-19c-1.0-1.x86_64.rpm
On RHEL you will need to manually get the prerequisites RPM from the Yum repository and run it manually before installing the database RPM.
curl -o oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm yum -y localinstall oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm rm oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
The ORACLE_HOME
for the software installation is "/opt/oracle/product/19c/dbhome_1".
Create Database
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".
# /etc/init.d/oracledb_ORCLCDB-19c configure Configuring Oracle Database ORCLCDB. Prepare for db operation 8% complete Copying database files 31% complete Creating and starting Oracle instance 32% complete 36% complete 40% complete 43% complete 46% complete Completing Database Creation 51% complete 54% complete Creating Pluggable Databases 58% complete 77% complete Executing Post Configuration Actions 100% complete Database creation complete. For details check the logfiles at: /opt/oracle/cfgtoollogs/dbca/ORCLCDB. Database Information: Global Database Name:ORCLCDB System Identifier(SID):ORCLCDB Look at the log file "/opt/oracle/cfgtoollogs/dbca/ORCLCDB/ORCLCDB.log" for further details. Database configuration completed successfully. The passwords were auto generated, you must change them by connecting to the database using 'sqlplus / as sysdba' as the oracle user. #
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.
Thoughts
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_HOME
for the software installation is "/opt/oracle/product/19c/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.
Vagrant Example
If you want to see it in action, you might want to try this Vagrant build here.
