For license management, a portal connection is required from the Assure UI portal to nodes where Precisely products are installed. The portal requires, at a minimum, one portal connection to either the source or the target node for a product instance.
For more information, see Implementation considerations for portal connections
MIMIX products limit communication among nodes based on their system role. It is preferred that your instance is configured with a management node as the primary portal connection in the instance domain. This will allow the Assure UI portal to apply license keys to all the nodes with a single action. For example, when you use the Update Instance Licenses wizard, it will update the license keys on all nodes in the Precisely product instance to which the primary portal connection can connect.
