Reboots are a thing of the past!

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 and 7, 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.

What gets patched?

Not all patches are created equal. Ksplice patches run-time security vulnerabilities and stability bugs. Whether it's the latest CVE targeting the network stack, an overflow in the DNS resolver, or a kernel panic caused by a poorly written driver, Ksplice will quickly provide protection to your system, without rebooting or restarting applications.
