4.1 About Ksplice Uptrack

Ksplice Uptrack can update a running Linux kernel without requiring an immediate reboot of the system. You can apply Ksplice updates to both the Unbreakable Enterprise Kernel and the Red Hat Compatible Kernel. Oracle creates each Ksplice patch from a kernel update that originates from either Oracle or the Linux kernel community. Ksplice Uptrack allows you to apply the latest kernel security errata for Common Vulnerabilities and Exposures (CVEs) without halting the system or restarting applications. Ksplice Uptrack applies the update patches in the background with a negligible impact, usually consisting of a pause of at most a few milliseconds. Ksplice Uptrack allows you to keep your systems secure and highly available. You can use Ksplice Uptrack and still upgrade your kernel using your usual mechanism, such as by using yum.
