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.
