Server-to-Server Processing

The following diagram shows the relationship of application components and WebSphere MQ when processing a server-to-server cooperative flow:

Diagram depcting the relationship of application components and WebSphere MQ

The two distinct CA Gen WebSphere MQ runtimes that are involved in processing a server-to-server flow are as follows:

WebSphere MQ server runtime is linked with the server manager, allowing the server manager to receive message requests and to return reply messages through its connected WebSphere MQ Queue Manager.
Communications runtime for WebSphere MQ allows a DPS server application to flow to another DPS. This is the same runtime that a DPC application uses (the CFB MsgObj and WebSphere MQ CoopFlow).

Server to server MQ cooperative flows are not supported within z/OS environments.
