You must include at least
one input node in a message flow. (For more information about using more than
one input node, see
Using more than one input node.
The one you choose depends on the source of the input messages:
- If the messages arrive at the broker on a WebSphere MQ queue, use the
supplied MQInput node.
- If the messages are sent by SCADA devices, use the SCADAInput node.
- If the message source is any other, you must use a user-defined input node.
