Ksplice is a technology that updates kernels with important security patches without the need to reboot. After its acquisition by Oracle, it is now offered as part of Oracle Linux Premier support. KernelCare was created by CloudLinux OS and is therefore independent of the distribution. KernelCare can support Oracle Linux kernels as well as CentOS, CloudLinux, Debian, RedHat, Virtuozzo, and many others, which makes it extremely useful for developers and IT teams.
Under normal conditions, in order to change from one program to another, you would need to uninstall one software completely and then install the new one, which could take time and a deep understanding of both programs. Luckily, a simple script has been created that will do all the work for you - without needing to restart your server or computer.
First, download and run this script:
$ wget https://downloads.kernelcare.com/ksplice2kcare
Run the command:
$ bash ksplice2kcare _YOUR_KERNELCARE_KEY_
If you are using IP licenses, run:
$ bash ksplice2kcare IP
The script checks two letters "IP" and assumes an IP license in this case.
