Abstract
A system for and method of sharing and executing inaccessible dynamic processes in replicated architecture networks to ensure that local activities are executed concurrently at remote workstations in a shared server-client network without the need for application modification in the system. The invention provides for sharing and executing inaccessible dynamic existing processes for replica consistency among multiple applications in the shared network. The invention provides for use at each workstation an application encapsulator having a listener to observe input events representative of process state changes. Each encapsulator also includes a mapper that operates with an associator for creating hierarchial tree structures to provide concurrent execution among all participant workstations. The invention uses a replica when an accessible process becomes inaccessible for multicasting input events to all participant workstations to maintain replica consistency among the plurality of applications. The invention is preferably used in engineering systems that include 3-D CAD/CAM graphical intensive applications and selectively with text/spreadsheet applications.
