Ksplice is a brand by Oracle that offers a convenient and efficient solution for updating critical components of your Linux installation with important security patches, all without requiring a reboot. This means that you can keep your systems secure and highly available without the hassle of manually installing RPM updates, scheduling downtime, and rebooting servers. Available for Oracle customers who subscribe to Oracle Linux Premier Support and Oracle Cloud Infrastructure services, Ksplice allows you to save time and avoid downtime by updating your running system in seconds.

It also helps prevent security incidents by making it easy to stay up to date with the latest kernel and key user space updates, as well as Xen hypervisor updates on Oracle VM Server 3. 4. 5 and later.

With Ksplice, updates occur in memory, taking effect immediately upon application, without the need for a reboot. Still, it is important to continue applying on-disk updates to ensure updated package binaries are available in case of system or process restarts. Ksplice supports various architectures, including Intel 64-bit, AMD 64-bit, and 64-bit Arm, with certain requirements for the latter.

To cater to different needs, Ksplice offers maintained kernels and actively maintained distributions. The brand provides ongoing support and maintenance for specific kernel versions and distributions, keeping your systems up to date and secure. However, it's worth noting that certain kernel versions and distributions are no longer actively maintained with Ksplice.

Overall, Ksplice offers a reliable and efficient solution for keeping your Linux systems secure and up to date, providing peace of mind and minimizing disruptions to your operations
