In a couple of places, you indicated that you are testing by MQPUTting message to, and MQGETting messages from the SYSTEM.CLUSTER.TRANSMIT.QUEUE.
It is highly unusual for any application to explicitly MQOPEN a transmit queue. If MQOPENed for output, the MQPUTting application would be responsible for creating an XQH (Transmission Queue Header) to provide routing information for the receiver-side message channel agent.
If, for example, you
| Code: |
| amqsput SYSTEM.CLUSTER.TRANSMIT.QUEUE <qmgrname> |
that would explain why messages ended up in the receiver-side DLQ - no XQH was present.
I may have misunderstood what you meant. Please clarify.

Thanks all.
@bruce2359 I tried to put it in another queue too.
So I setup a debugger on the OS (where MQ is) and found the code is complaining about MQ_USE_MQCSP_AUTHENTICATION being null. (which likely means the call is not even reaching MQ)
I read about it but am not sure what to set it for 7.1.
Please help. |

I don't understand what you mean by this.

So that's a JMeter thing (most recent update in GitHub Proejct it would appear).
| Code: |
| * **mq_use_mqcsp_authentication**: The connection authentication used. Set false for Compatibility mode, or true for MQCSP authentication. |
If you're not passing in a user ID and password, then it doesn't matter one jot. MQ V7.1 does support MQCSP but ignores it unless you have an exit to do something with it. SO still doesn't matter if you are passing in a user ID and password.
Suggest you set it to false to get round the null complaint.
Cheers,
Morag

Please display the Dead Letter Header. This will help determine the underlying cause of your grief.

Setting mq_use_mqcsp_authentication to false worked!
Thank you so much!
Still a couple of questions remain in my mind -
1. Why is MQ treating connection from my mac as psqr while from local OS as something else?
2. Why mq_use_mqcsp_authentication = false worked? |

There will be different assignments of identity going on depending on which machine you are coming from. It sounds like JMeter is Java, so the identity picked up to use as the client machine could be affected by setting a user id (that's something that mq_use_mqcsp_authentication = false also allows), or you could simply have different settings. You haven't showed us all the user id settings in both setups so hard to say for sure.

Sounds like JMeter wasn't even trying the connection when you had a null value in there.

You mean the output of ENTAUTH command for myuser id on the QMgr and the Q (vs psqr)?

It didn't need that from my local mac  |

no, I mean how your user ID gets chosen. Which user you're running it under, whether you set a user in the program, if you have CHLAUTH rules, etc, etc

Are you using the same version of JMeter? It was the most recent update to the MQMeter plugin.
