3.1.2 About Ksplice Updates

When a critical bug or security vulnerability is discovered in the Linux kernel, Oracle produces a new kernel release and prepares a rebootless update corresponding to that release. The rebootless update is securely distributed using the Oracle Ksplice Uptrack server and the Unbreakable Linux Network (ULN) and is applied to your systems by the Ksplice Uptrack client or Ksplice Enhanced client with zero downtime. Your infrastructure is again up to date and secure.
