To confirm whether a particular kernel is supported, install the Ksplice Uptrack client or Ksplice Enhanced Client on a system that is running the kernel.

Note

If your system is currently running Red Hat Enterprise Linux (RHEL) and you recently migrated to Oracle Linux Premier Support, you can use Ksplice to update the existing Red Hat Enterprise Linux kernel. You do not need to switch to the Red Hat Compatible Kernel to use Ksplice kernel patches. These patches are available on ULN as uptrack-updates-kernel_version packages in the Ksplice for Oracle Linux channels.
