About This Guide

Subscription Management Tool (SMT) for SUSE Linux Enterprise 12 SP4 allows enterprise customers to optimize the management of SUSE Linux Enterprise software updates and subscription entitlements. It establishes a proxy system for SUSE® Customer Center with repository (formerly known as catalog) and registration targets. This helps you centrally manage software updates within the firewall on a per-system basis, while maintaining your corporate security policies and regulatory compliance.

SMT allows you to provision updates for all of your devices running a product based on SUSE Linux Enterprise. By downloading these updates once and distributing them throughout the enterprise, you can set more restrictive firewall policies. This also reduces bandwidth usage, as there is no need to download the same updates for each device. SMT is fully supported and available as a download for customers with an active SUSE Linux Enterprise product subscription.

Subscription Management Tool provides functionality that can be useful in many situations, including the following:

  • You want to update both SUSE Linux Enterprise and RedHat Enterprise Linux servers.

  • You want to get a detailed overview of your company's license compliance.

  • Not all machines in your environment can be connected to SUSE Customer Center to register and retrieve updates for bandwidth or security reasons.

  • There are SUSE Linux Enterprise hosts that are restricted and difficult to update without putting in place a custom update management solution.

  • You need to integrate additional software update external or internal repositories into your update solution.

  • You are looking for a turnkey box staging solution for testing updates before releasing them to the clients.

  • You want to have a quick overview of the patch status of your SUSE Linux Enterprise servers and desktops.
