Oracle Cloud Infrastructure Documentation

Oracle Autonomous Linux Image

The Oracle Autonomous Linux platform image is based on Oracle Linux and is used to create Autonomous Linux instances. Autonomous Linux instances are managed using the Autonomous Linux service in Oracle Cloud Infrastructure.

Autonomous Linux provides the following features:

  • Automatic daily updates, including zero-downtime Ksplice updates for kernel, OpenSSL, and glibc libraries.
  • Monitoring for critical events, such as a kernel oops or kernel crashes, including collecting and submitting the messages and logs needed to debug and provide a root cause analysis of the event.

For more information, see Oracle Autonomous Linux.

The image includes the release packages for the ol7_developer and ol7_developer_EPEL repositories, but these repositories are disabled by default. If you need packages from these repositories, you can install the appropriate release package to obtain the correct repository configuration before enabling the repository by using the following commands: 

sudo yum install oraclelinux-developer-release-el7
sudo yum install oracle-epel-release-el7
Note

Packages found in the ol7_developer and ol7_developer_EPEL repositories are only entitled to basic installation support.

Oracle Instant Client 18.3 basic package cannot be updated to 19.5 on instances that were launched before March 18, 2020 because of changes to packaging. To update Oracle Instant Client, manually remove Oracle Instant Client 18.3, and then install 19.5. Use the following commands:

sudo yum remove oracle-instantclient18.3-basic
sudo yum install oracle-instantclient19.5-basic

On Oracle Autonomous Linux images that were launched after March 18, 2020, Oracle Instant Client is not installed by default. To install Oracle Instant Client 19.5, you must manually install the package. Use the following command:

sudo yum install oracle-instantclient19.5-basic

On Oracle Autonomous Linux images that were launched after December 9, 2020, the Oracle Instant Client repository (ol7_oracleinstant client) is not available by default. To add the repository, you must first install the oracle-release-el7 release package and then enable the ol7_oracle_instantclient repository. You can then install the appropriate Oracle Instant Client version package. Use the following commands:

sudo yum install oracle-release-el7
sudo yum-config-manager --enable ol7_oracle_instantclient
