About Linux Updates in OS Management
OS Management uses the following categories for patch updates:
- All
- Security
- Bug Fix
- Enhancement
- Ksplice
- Other
| OS Management Category | Description |
|---|---|
| All | An update that includes all available updates. |
| Security |
An update that addresses security vulnerabilities found during development, testing, or reported by users. Security fixes usually have one or more associated CVE (Common Vulnerabilities and Exposure) names to identify the vulnerabilities. Ksplice updates are included for this category. |
| Bug Fix | An update that fixes issues reported by users or discovered during development or testing. |
| Enhancement | An update that introduces new features, improved functionality, or enhanced performance in the package's software. |
| Ksplice |
An update used by Ksplice for installing zero-downtime security patches. For more information about Ksplice updates in OS Management, see About Ksplice Updates in OS Management. For general information about Ksplice in Oracle Linux, see Oracle Linux Ksplice User's Guide. |
| Other | An update that is not associated with any errata. |
About Ksplice Updates in OS Management
Ksplice updates your running instances with the latest kernel and key user space security and bug fix updates, keeping them secure and highly available. For more information, see the Oracle Linux Ksplice User's Guide.
- OS Management only includes Ksplice updates when Ksplice support is enabled. Oracle Linux and Oracle Autonomous Linux instances deployed from platform images automatically enable Ksplice. Autonomous Linux instances use Ksplice technology to run zero-downtime patching.
- Ksplice support requires Oracle Cloud Agent 1.14.2 or later. If you have an earlier version of the Oracle Cloud Agent, see Updating the Oracle Cloud Agent Software.
- Ksplice Updates for Managed Instances
-
OS Management includes all available Ksplice updates when you perform the following actions on a managed instance: Install All Updates and Install Security Updates.
For more information, see Installing Packages on a Managed Instance.
- Ksplice Updates for Managed Instance Groups
-
OS Management provides a separate Ksplice update type for applying all Ksplice updates to instances that are part of a managed instance group. OS Management includes all available Ksplice updates when you select All, Security, or Ksplice as the update type on the Install All Updates panel for a managed instance group.
For more information, see Installing Packages on a Managed Instance Group.
