How to send message with RFH2 format?

问题

Question

I need to inject messages in IBM MQ with JMeter.

Format should be RFH2. I need to set Format field to empty and also change content of the header.

Which kind of JMeter object should I used to do that?

Can you help me please? Thanks a lot.

Update n°1

Thank to @DmitriT answer I'm able to send message in queue.

However, it seems that header content is not put in the header but before the message. Please find below an example:

Server logs with message sent with MQ Visual Edit

Header

 2020-04-21 11:07:59.913 DEBUG 48093 --- [DefaultMessageListenerContainer-2] 
 c.b.i.c.listeners.AbstractAgiListener    : Receive message on MQ with header : {someargs, 
 jms_destination=queue:///myqueue, someargs, Sender=mysender, someargs, jms_type=mcd://jms_byte,
 someargs}

Message

 <Document ...>...</Document>

Any idea how to solve it please? Thank you.

The "JMeter object" you should use is JSR223 Sampler

1. Download the relevant version of the com.ibm.mq.allclient library (with dependencies) and drop it to JMeter Classpath
2. Restart JMeter to pick the libraries up
3. Add JSR223 Sampler to your Test Plan

4. Create the message according to your requirements and publish it to the queue. Reference code:

   import com.ibm.mq.MQAsyncStatus
   import com.ibm.mq.MQMessage
   import com.ibm.mq.MQPutMessageOptions
   import com.ibm.mq.MQQueueManager
   import com.ibm.mq.constants.CMQC
   import com.ibm.mq.constants.MQConstants
   import com.ibm.mq.headers.MQRFH2
   
   def mqProps = new Hashtable<String, Object>()
   mqProps.put(MQConstants.CHANNEL_PROPERTY, 'DEV.APP.SVRCONN')
   mqProps.put(MQConstants.PORT_PROPERTY, 1414)
   mqProps.put(MQConstants.HOST_NAME_PROPERTY, '192.168.99.100')
   
   def qManager = 'QM1'
   def queueName = 'DEV.QUEUE.1'
   
   
   def qMgr = new MQQueueManager(qManager, mqProps)
   def openOptions = MQConstants.MQOO_OUTPUT | MQConstants.MQOO_INPUT_AS_Q_DEF
   def queue = qMgr.accessQueue(queueName, openOptions)
   
   def pmo = new MQPutMessageOptions()
   pmo.options = MQConstants.MQPMO_ASYNC_RESPONSE
   def message = new MQMessage()
   def rfh2 = new MQRFH2()
   rfh2.setEncoding(CMQC.MQENC_NATIVE)
   rfh2.setCodedCharSetId(CMQC.MQCCSI_INHERIT)
   rfh2.setFormat(CMQC.MQFMT_STRING)
   rfh2.setNameValueCCSID(1208)
   rfh2.setFieldValue('your', 'data', 'here')
   rfh2.write(message)
   
   queue.put(message, pmo)
   queue.close()
   
   MQAsyncStatus asyncStatus = qMgr.getAsyncStatus()
   log.info('Successfully published: ' + asyncStatus.putSuccessCount + ' message(s)')
