Do you know anything about Oracle Ksplice?
In short Ksplice is a upgrade tools available for Oracle Linux.
What does Ksplice update?
- The kernel with critical security patches
- glibc and OpenSSL user space libraries with critical security patches (Oracle Linux only)
Do I need to continue regular maintenance updates?
Yes, continue to apply updates to your entire system at regular intervals based on your organization's best practices.
Ksplice updates occur in-memory, effectively making the change immediate without a reboot. This is different than a traditional kernel update, which requires a reboot to update the system. Ksplice applies critical security patches, but there are other errata updates and bug fixes you should apply at regular intervals.
In detail it's available to Oracle Linux customers with Oracle Linux Premier Support, Oracle Ksplice updates select, critical components of your Oracle Linux installation with all of the important security patches without needing to reboot.
With rebootless updates, you can:
- Save time and pain by updating in seconds, while your systems are running.
- Avoid downtime.
- Prevent disastrous security incidents by making it easy to stay up to date.
Linux distributions require a reboot about once a month to stay up to date with important kernel and user-space security updates.
Oracle Ksplice allows you to apply the same updates, without rebooting that would normally require an update with your package manager and a reboot.
Oracle Linux is the only Linux distribution to offer zero-downtime updates for select, critical user-space components.
With Oracle Linux 6, 7, 8 and 9, Ksplice can patch glibc and openssl vulnerabilities whilst the system is running, without stopping applications and without interruption. This feature is exclusive to Oracle Linux Premier Support customers.
