Install Oracle Linux and configure your Oracle Linux installation for security errata or bug fix updates using the Oracle Linux yum server.

1. Refer to the official Oracle Linux documentation to install Oracle Linux:
   • Oracle Linux 7

     Oracle Linux 7 Installation Guide

     Oracle Linux 7: Managing Software

   • Oracle Linux 8

     Oracle Linux 8 Installation Guide

     Oracle Linux 8: Managing Software

2. After you have completed your Oracle Linux installation, run the command yum update as needed to obtain the most current security errata and bug fixes for your Oracle Linux installation.
3. Restart your system.
4. Start a terminal session and enter the following command as root:
   • Oracle Linux 7

     # yum install oracle-database-preinstall-19c

     Note:

     Use the -y option if you want yum to skip the package confirmation prompt.
   • Oracle Linux 8

     # dnf install oracle-database-preinstall-19c

     Note:

     Use the -y option if you want yum to skip the package confirmation prompt.

     You should see output indicating that you have subscribed to the Oracle Linux channel, and that packages are being installed.

     The Oracle Database Preinstallation RPM automatically creates a standard (not role-allocated) Oracle installation owner and groups and sets up other kernel configuration settings as required for Oracle installations. If you plan to use job-role separation, then create the extended set of database users and groups depending on your requirements.
