Optional: Synchronizing Products from SUSE Customer Center

SUSE Customer Center (SCC) maintains a collection of repositories which contain packages, software and updates for all supported enterprise client systems. These repositories are organized into channels each of which provide software specific to a distribution, release, and architecture. After synchronizing with SCC, clients can receive updates, be organized into groups, and assigned to specific product software channels.

This section covers synchronizing with SCC from the Web UI and adding your first client channel.

For Uyuni, synchronizing products from SUSE Customer Center is optional.

Before you can synchronize software repositories with SCC, you will need to enter organization credentials in Uyuni. The organization credentials give you access to the SUSE product downloads. You will find your organization credentials in https://scc.suse.com/organization.

Enter your organization credentials in the Uyuni Web UI:

Procedure: Entering Organization Credentials
  1. In the SUSE Manager Web UI, navigate to Main Menu  Admin  Setup Wizard.

  2. In the Setup Wizard page, navigate to the Organization Credentials tab.

  3. Click Add a new credential.

  4. Enter a username and password, and click Save.

A check mark icon is shown when the credentials are confirmed. When you have successfully entered the new credentials, you can synchronize with SUSE Customer Center.

Procedure: Synchronizing with SUSE Customer Center
  1. In the Uyuni Web UI, navigate to Admin  Setup Wizard.

  2. From the Setup Wizard page select the SUSE Products tab. Wait a moment for the products list to populate. If you previously registered with SUSE Customer Center a list of products will populate the table. This table lists architecture, channels, and status information. For more information, see Wizard.

  3. If your SUSE Linux Enterprise client is based on x86_64 architecture scroll down the page and select the check box for this channel now.

    • Add channels to Uyuni by selecting the check box to the left of each channel. Click the arrow symbol to the left of the description to unfold a product and list available modules.

    • Click Add Products to start product synchronization.

After adding the channel, Uyuni will schedule the channel to be synchronized. This can take a long time as Uyuni will copy channel software sources from the SUSE repositories located at SUSE Customer Center to local /var/spacewalk/ directory of your server.

In some environments, transparent huge pages provided by the kernel can slow down PostgreSQL workloads significantly.

To disable transparent huge pages, set the transparent_hugepage kernel parameter to never. You will also need to open the /etc/default/grub file and add or edit the line GRUB_CMDLINE_LINUX_DEFAULT. For example:

GRUB_CMDLINE_LINUX_DEFAULT="resume=/dev/sda1 splash=silent quiet showopts elevator=noop transparent_hugepage=never"

To write the new configuration run grub2-mkconfig -o /boot/grub2/grub.cfg.

Monitor the channel synchronization process in real-time by viewing channel log files located in the directory /var/log/rhn/reposync:

tail -f /var/log/rhn/reposync/<CHANNEL_NAME>.log

When the channel synchronization process is complete, you can continue with client registration. For more instructions, see Client Registration Overview.
