Endpoint monitoring system
In order to create an endpoint monitoring system you need to have Delivery Manager
running on two framework servers, using identical configuration profiles. When two
instances with the same name are started, the one that started first becomes the main (or
promoted) instance and the one that started second becomes the backup instance.
The backup instance monitors the main instance and if the main instance stops responding,
the backup instance will promote itself and all jobs pass over to it. The backup will remain
as the promoted instance from that point on, even if the original main instance is restored.
The relationship is not hierarchical and it is not possible to have two instances with the same
name under the control of one Delivery Manager instance.
Figure 1-4 below shows the same two endpoints (A and B) are configured on two instances
of Delivery Manager. Cloning endpoints reduces the risk of an individual endpoint failure
causing media transfers to stall.
