Event publication between cells use pattern

Implementation of this use pattern uses existing functionality of the service integration bus. WS-Notification services are configured in each of two cells, and a service integration bus link is configured to link the service integration bus topic spaces between the two buses.

This configuration means that any messages published to a service integration bus topic space (either by the notification broker or a standard client of the bus) is transmitted to the foreign bus. For more information, see Configuring service integration bus links.

Note that this bridging of topic spaces is only permitted for permanent WS-Notification topic namespaces, and not for dynamic topic namespaces.

Two cells are shown, each on a separate bus; Each cell contains two application servers, and each application server contains a WS-Notification service and messaging engine; There is a link between the two messaging engines within each cell, and an SIBus link between the two buses. Consequently, requests received by either server in one cell are available to consumers associated with either server in the other cell.
