MQSeries Adapter Message Flow
A message originating from a BizTalk Server computer is first passed to an MQSeries Server running on Windows. MQSeries Server running on Windows can be on the same computer as the one that runs BizTalk Server. The message is routed through the MQSeries Server for Windows computer to an MQSeries Server host on an operating system such as UNIX. An application then retrieves the message from the MQSeries queue.
A message originating from an application first goes to an MQSeries queue on MQSeries Server. The MQSeries Server forwards the message to the MQSeries Server for Windows computer. BizTalk Server receives the message from the MQSeries Server for Windows computer and forwards it to the appropriate application.
The MQSeries adapter supports the following messaging scenarios.
| Scenario | Description |
|---|---|
| Receive | The adapter receives a message from MQSeries Server, which is passed to BizTalk Server. |
| Send (Static One-Way Port) | The adapter routes a message that originates from BizTalk Server. |
| Dynamic Send | Enables the application to select a destination address (URI) at run time. |
| Dynamic Receive | Enables the application to select a source address (URI) at run time by setting the MQSeries.DynamicReceive context property to Yes and specifying the dynamic receive address. |
| Correlation | Messages from the adapter are correlated with specific instances of an orchestration that can handle more than one type of message. MQSeries Server can create the correlation identifier by using solicit-response, or BizTalk Server can create the correlation identifier. For more information about correlation sets, see BizTalk Server Help. |
For more information about using ports and adapters in pipelines, orchestrations, and content-based routing, see BizTalk Server Help. For more information about using correlation identifiers in the adapter, see Correlating Messages Using Request-Reply.
