OS upgrade on OCI Oracle DB system in Base Database service using OCI console

OS upgrade on OCI Oracle DB system in Base Database service using OCI console

 

Pre check

1) Before applying, run a "Precheck" to ensure prerequisites are met and ensure that no 3rd party modules/softwares are no installed

2) Back up the database in the DB system prior to attempting an OS update.

3) Do not remove packages from a DB system. However, you might have to remove custom RPMs (packages that were installed after the system was provisioned) for the update to complete successfully.

4) Oracle recommends that you test any updates thoroughly on a non-production system before updating a production system.

5) The image used to launch a DB system is updated regularly with the necessary updates. After you launch a DB system, you are responsible for applying the required OS security updates published through the Oracle public YUM server.

5) To apply OS updates, the virtual cloud network (VCN) in the DB system must be configured to allow access to the YUM repository. For more information, see VCN and Subnets.

Steps

1. On the DB Systems list page, select the DB system that you want to work with. If you need help finding the list page or the DB system, see List the DB Systems.
2. On the details page, select the Updates (OS) tab to view the list of available OS upgrades for the DB system.
3. From the Actions menu for the upgrade you are interested in, select one of the following actions:
   • View details: View the details about this upgrade.
   • Precheck: Check for any prerequisites to ensure that the upgrade can be successfully applied.
   • Apply update: Applies the selected upgrade. Oracle recommends that you run the precheck operation for an upgrade before applying it.
