Consuming Messages from IBM Message Queues¶

Purpose¶

This application demonstrates how to consume events from IBM Message Queue and publish messages in to a IBM Queue

Prerequisites¶

Ensure that there is a running IBM MQ instance.
Create a queue manager named ESBQManager, Queue named Queue1 and channel named Channel1
Download com.ibm.mq.allclient_9.0.5.0_1.0.0.jar and javax.jms-api-2.0.1.jar and copy to /lib directory.

Executing the Sample¶

Start the Siddhi application by clicking on 'Run'
If the Siddhi application starts successfully, the following messages would be shown on the console
- IBMMessageQueueSample.siddhi - Started Successfully!

Testing the Sample¶

Simulate single events. For this, click on 'Event Simulator' (double arrows on left tab) -> 'Single Simulation' -> Select 'IBMMessageQueueSample' as 'Siddhi App Name' -> Select 'SweetProductionSinkStream' as 'Stream Name' -> Provide attribute values -> Send

Viewing the Results¶

See the output on the console.
