3.4 Upgrading Your System

To upgrade your system to UEK R4:

  1. After enabling access to the appropriate channels, including ol6_UEKR4 or ol7_UEKR4, in the Oracle Linux yum server repository or ol6_x86_64_UEKR4 or ol7_x86_64_UEKR4 on ULN, run the following command to upgrade the system to UEK R4:

    # yum update
  2. After upgrading the system, reboot it, selecting the UEK R4 kernel (version 4.1.12) if this is not the default boot kernel.

For instructions on how to install the Oracle-supported OFED packages after upgrading to UEK R4, see Section 3.5, “Installing the Oracle-Supported OFED Packages”.

If you have questions regarding configuring or using yum to install updates, refer to the Oracle Linux Unbreakable Linux Network User's Guide.

The kernel's source code is available via a public git source code repository at https://oss.oracle.com/git/?p=linux-uek.git;a=summary.
