Controlling the WebSphere Message Broker Exit BTM extension

A user exit for WebSphere Message Broker is provided as a dynamic (or shared) library that is loaded into the DataFlowEngine (the execution group process) when the broker is started. The exit runs as part of an execution group. TrueSight Middleware and Transaction Monitor supports WebSphere Message Broker 6.0.0.1 or higher.

The WMB Exit BTM Extension monitors these activities:

• any time a message is read into a flow by an input node
• any time a message is passed from one node to the next.

For installing the WMB exit you must point the broker to the directory where the exit is located running the mqsichangebroker command:mqsichangebroker broker -x path_to_wmb_exit

mqsichangebroker BROKER -x c:\btm\wmbexit

Running this command makes the broker aware of the exit and makes the broker load the exit on startup. But it does not activate the exit.
