When the primary node fails over to the secondary node, the service group that is online on the primary node switches to the secondary node. At this point, all the resources except the Adaptive Server binary are online on the secondary node. The Adaptive Server on the secondary node takes over these resources.
When one service group fails over from the primary host
to the secondary host, the Adaptive Server on the secondary host
takes over all primary resources, but the Adaptive Server on the
failed-over group is not started.
