Abstract
A redundant host pair runtime arrangement is disclosed for a process control network environment. The arrangement includes a primary network. A first partner of a fail-over host pair operates on a first machine communicatively connected to the primary network. The first partner hosts a set of executing application components in accordance with an active role assigned to the first partner. A second partner of the fail-over host pair operates on a second machine communicatively connected to the primary network. The second partner hosts a non-executing version of the set of executing application components in accordance with a standby runtime role. A monitoring process, operating separately upon the first machine, senses a failure of the first partner, and in response, initiates a notification to the second partner to take over the active role.
