Event publication between cells topology
這個拓蹼的實作使用服務整合匯流排現有的功能。WS-Notification 服務分別配置在兩個 Cell 中,另外還配置服務整合匯流排鏈結,將兩個匯流排的服務整合匯流排主題空間鏈結起來。
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.
In the following figure, 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 a bus link between the two buses. Requests received by either server in one cell are available to consumers associated with either server in the other cell.
