3.1 Installing Ksplice Uptrack From ULN

If you have an Oracle Linux Premier support subscription, a Premier Limited subscription, or an Oracle Premier Support for Systems and Operating Systems support subscription, you are automatically registered to use Oracle Ksplice. You can configure your registered systems to use Ksplice Uptrack through the Ksplice for Oracle Linux channel on ULN by using the yum command. See Section 1.3.2, “About Oracle Ksplice and ULN Registration”.

The system on which you want to install Ksplice Uptrack must also meet the following requirements:

Must have access to the Internet.
Must be registered with ULN.
Must be running Oracle Linux 5, Oracle Linux 6, or Oracle Linux 7 with a supported version of either the Unbreakable Enterprise Kernel or the Red Hat Compatible Kernel installed. You can verify the kernel version by using the uname -a command. See Section 1.1.1, “Supported Kernels”.
The kernel that is currently running is also the kernel you want to update, as Ksplice Uptrack applies updates only to the running kernel.

To install Ksplice Uptrack from ULN, follow these steps:

Log in as root on the system.
If you use an Internet proxy, configure the HTTP and HTTPS settings for the proxy in the shell.
- For the sh, ksh, or bash shells, use commands such as the following:
```
# http_proxy=http://proxy_URL:http_port
# https_proxy=http://proxy_URL:https_port
# export http_proxy https_proxy
```
  For the csh shell, use commands such as the following:
```
# setenv http_proxy=http://proxy_URL:http_port
# setenv https_proxy=http://proxy_URL:https_port
```
Using a browser, log in at https://linux.oracle.com with your ULN user name and password.
Perform the following steps:
1. On the Systems tab, click the link that is named for your system in the list of registered machines.
2. On the System Details page, click Manage Subscriptions.
3. On the System Summary page, select the Ksplice for Oracle Linux channel for the correct release and your system's architecture (i386 or x86_64) from the list of available channels, then click the right arrow (>) to move it to the list of subscribed channels.
4. Click Save Subscriptions and log out of ULN.
On your system, use the yum command to install the uptrack package.
```
# yum install -y uptrack
```
The access key for Ksplice Uptrack is retrieved from ULN and added to /etc/uptrack/uptrack.conf, for example:
```
[Auth]
accesskey = 0e1859ad8aea14b0b4306349142ce9160353297daee30240dab4d61f4ea4e59b
```
To enable the automatic installation of updates, change the value of the autoinstall entry in the /etc/uptrack/uptrack.conf file from no to yes:
```
autoinstall = yes
```
