Oracle Autonomous Linux In 2006, with the objective of proposing a more complete end-to-end software stack along with their database, Oracle decided to have their own distribution of Linux by modifying and compiling the Red Hat Enterprise Linux binaries. This new distribution is now called Oracle Linux and it’s the operating system (OS) of choice for Oracle Cloud Infrastructure, Oracle Cloud at Customer, Oracle Engineered Systems like Exadata, and others. For your on-premise needs, you can also download this product for free from Oracle Software Delivery Cloud. During Oracle OpenWorld in 2019, Larry Ellison, Oracle co-founder and CTO, announced the first autonomous operating system, Oracle Autonomous Linux. This version of Linux provisions itself, tunes itself, and also patches itself. In this chapter, we will discover the benefits of using this new Autonomous Linux and why this should be used as much as possible.
What Autonomous Means Oracle’s first automated product was the database. Autonomous Database handles all the manual tasks that database administrators (DBA) were used to be responsible for, from the creation, patching process, backups, and tuning. Oracle wanted to come up with an operating system that would also reduce the day-to-day tasks that system administrators were responsible for. Autonomous Linux with the new service Oracle OS Management Service (OS Management Service can be used on non-Autonomous Linux as well) handles the day- to-day, common management tasks like patching, package management, compliance reporting, and configuration management. The Oracle Ksplice feature enables the system to keep the kernel up to date with the latest critical fixes, minimizing the maintenance cost and planned downtime.

Note Ksplice requires Internet access. You have to add and configure the NAT Gateway or Internet Gateway to your VCN.
How to Provision Autonomous Linux Creation of the Notification Topic Before we create the new Autonomous Linux, we have to have a notification topic which will be used by Autonomous Linux to send notifications. I invite you to follow the instruction in Chapter 9 which covers this topic. We will create a topic called “AutonomousLinux” and subscribe to this topic. We will need the “Notification Topic Oracle Identifier (OCID)” during the provisioning process of the Autonomous Linux Compute Instance.
Creation of the Compute Instance You can refer to Chapter 4 where we explain how to provision a new Compute Instance. During the provisioning process, make sure to select one of the available images “Oracle Autonomous Linux”. During the process, we will have to provide the Notification Topic OCID we would like the Autonomous Linux to use to send notifications. During the provisioning process, make sure to click “Show Advanced Options” where we see instructions to configure Autonomous Linux t
