Subscribing a system to ULN channels causes the system to automatically receive package updates when these become available on those channels.

1. Sign in to https://linux.oracle.com with valid SSO credentials.
2. (Optional) View the available channels to which you can subscribe the system.
   1. Select the Channels tab.
   2. Use the Release and Architecture drop-downs to limit the listing to a particular OS release and architecture.
3. Manage the system's subscription information.
   1. Select the Systems tab and from the list of registered machines, select the system whose subscriptions you want to manage.
   2. On the System Details page, select Manage Subscriptions.
   3. On the System Summary page, select channels from the list of available or subscribed channels and select the arrows to move the channels between the lists.
      Moving channels between the available list and the subscribed list either adds or removes a channel subscription.

      Caution:

      Unsubscribing from the _latest channel can make the system vulnerable to security-related issues. We recommend that you always keep the system subscribed to the _latest channel.
4. After you have finished selecting channels, select Save Subscriptions.
