This document describes how to prepare for and perform Oracle Linux kernel upgrade.
The article is specifically intended for Linux System Administrators.
The document is intended for point release kernel upgrade only e.g. 2.6.18-a to 2.6.18-b or 2.6.39-x to 2.6.39-y , rather than major version upgrade e.g. 2.6.18-x to 2.6.39-b.
The procedure described solely focuses on kernel-specific/dependent modules, rather than generic packages.
