Appl. No.:

10/944476

Inventors:

Derrick C. Jones - Huntington Beach CA, US
Douglas P. Kane - Silverado CA, US

Assignee:

Invensys Systems, Inc. - Foxboro MA

International Classification:

G06F 15/16
G06F 11/00

US Classification:

709229, 714 13

Abstract:

A system is disclosed for providing transparency between fail-over host partners for data acquisition clients of a redundancy-enabled host in a supervisory process control data acquisition application runtime environment. The system includes a name resolution table for mapping location-independent reference names to network location-specific addresses. A location-independent name is assigned to the redundancy-enabled host comprising an active host partner and a standby host partner. A messaging infrastructure serves clients of the redundancy-enabled host. The messaging infrastructure maintains a name to address translation for each reference of the client to subscribed data on the redundancy-enabled host such that a same name is used to reference data on the redundancy-enabled host without regard to which one of the redundancy-enabled host partners is presently active.

US Classification:

714 13, 714 4

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.

International Classification:

US Classification:

370216000

Abstract:

A redundant host pair runtime arrangement is disclosed for a process control network environment. The environment includes a primary network through which process control information is transmitted. An active partner of a fail-over host pair operates on a first machine communicatively connected to the primary network, and the active partner hosts a set of executing application components. A standby partner of the fail-over host pair operates on a second machine communicatively connected to the primary network. The standby partner receives updates including engine synchronization data associated with the set of executing application components to facilitate taking over an active partner role in response to a fail-over event. The environment also includes a redundancy message channel, separate and distinct from the primary network. The redundancy message channel provides a communications path between the first machine and second machine facilitating passing the updates including engine synchronization data.
