Enabling Access to Oracle Yum Channels

On the Oracle Linux yum server at https://yum.oracle.com/, the kernel image and userspace packages are available on the following channels.

For Oracle Linux 6:

ol6_latest (latest user-space packages for Oracle Linux 6 other than the OFED tool packages)
ol6_UEKR4 (kernel-uek*, dtrace-modules-*, and libdtrace-*)
ol6_UEKR4_OFED (latest OFED tools packages)

For Oracle Linux 7:

ol7_latest (latest user-space packages for Oracle Linux 7 other than the OFED tool packages)
ol7_UEKR4 (kernel-uek*, dtrace-modules-*, and libdtrace-*)
ol7_UEKR4_OFED (latest OFED tools packages)

Note:

To be able to install UEK R4, enable the appropriate ol6_UEKR4 or ol7_UEKR4 channel and disable the ol6_UEKR3_latest or ol7_UEKR3 channel.

The DRBD (Distributed Replicated Block Device) packages are not available on the Oracle Linux yum server.

To enable access to the Oracle Linux 6 repositories on the Oracle Linux yum server, use yum-config-manager. For example, to enable access to the ol6_latest and ol6_UEKR4 repositories, run the following:

# yum-config-manager --enable ol6_latest,ol6_UEKR4

To enable access to the Oracle Linux 7 repositories on the Oracle Linux yum server, use yum-config-manager. For example, to enable access to the ol7_latest and ol7_UEKR5 repositories, run the following:

# yum-config-manager --enable ol7_latest,ol7_UEKR5

Note:

You can only use yum-config-manager to enable or disable repositories where you already have a configuration file for the specified repository. Repository configurations are typically stored in /etc/yum.repos.d. The repository configurations required to install UEK on Oracle Linux 7 are included in the oraclelinux-release-el7 package. The repository configurations required to install UEK on Oracle Linux 6 are included in the oraclelinux-release-el6 package. If you do not have the yum-config-manager command available you may need to install the yum-utils package.
