[SOLVED] Set threshold and back-out queue programatically for IBM MQ

Set threshold and back-out queue programatically for IBM MQ

Is there a way to set the back-out threshold and back-out queue in Java? I don't have access to MQ Console to manually set these as I am using Testcontainers. So each test run should set these property on the queue. Currently I am using JMS to send messages to the queue, and I want to set a threshold to 3 so as soon as the threshold reaches I will transfer the message to the back-out queue. Currently the message redelivers indefinitely.

I tried using MQ as shown in this article. However, it just sends a message to the queue.

After reading the comments I tried doing through PCF


PCFMessageAgent agent = new PCFMessageAgent(queueManager);
PCFMessage request = new PCFMessage(MQConstants.MQCMD_CHANGE_Q);
request.addParameter(MQConstants.MQCA_Q_NAME, queueName);
request.addParameter(MQConstants.MQIA_BACKOUT_THRESHOLD, 3);
request.addParameter(MQConstants.MQCA_BACKOUT_REQ_Q_NAME, backoutQueue);
agent.send(request);

It just throws PCFException MQJE001: Completion Code 2, Reason 3014.

Solution

Thanks to @Morag for pointing me to right direction. For anyone who wants to setup.


   PCFMessageAgent agent = new PCFMessageAgent(queueManager);
   PCFMessage request = new PCFMessage(MQConstants.MQCMD_CHANGE_Q);
   request.addParameter(MQConstants.MQCA_Q_NAME, queueName);
   request.addParameter(MQConstants.MQIA_Q_TYPE, MQConstants.MQQT_LOCAL);
   request.addParameter(MQConstants.MQIA_BACKOUT_THRESHOLD, 3);
   request.addParameter(MQConstants.MQCA_BACKOUT_REQ_Q_NAME, backoutQueue);
   agent.send(request);
