Hi,
I am running into an issue when trying to segment message over 4 MB(5.2 MB message).
My JAVA application uses MQ API,sits on the same box as the message broker and writes to a local queue with following options:
qMessage = new MQMessage();
qMessage.messageFlags = MQC.MQMF_SEGMENTATION_ALLOWED;
qMessage.setVersion(MQC.MQMD_VERSION_2);
Now I am running into following error when reading the message back on the same box:
MQPUT failed: MQCC=2; MQRC=2030.
My options on a get are:
gmo.options = MQC.MQGMO_WAIT | MQC.MQGMO_FAIL_IF_QUIESCING | MQC.MQGMO_COMPLETE_MSG;
Looks like MQPUT fails when writing this message to a dynamic queue on the same box as the broker with 2030.
With segmenation,I am guessing I dont have to change MQXMSGLENGTH parameter on any of the queues?
MAXMSGLENGTH on the queue manager is 100MB.
thanks |

I'm confused.
You're getting a 2030 on your PUT, or your GET?

| sorry for the confusion. MQPUT(trying to write to dynamic queue) in the message flow fails with 2030 and my application reading fro this dynamic queue fails with 2033. |

I hope it explains everything.

Right, so the message never gets PUT because of the 2030, so it's not available to be GOT.
Are your messages persistent? If so you probably need to specify SYNCPOINT.

You say Max message length for the queue manager is 100Mb but what is it for the queue?
| Code: |
| dis q(<qname>) maxmsgl |

Maybe you should check channel max message size too.

I believe it shouldn't matter what the queue MaxMsgLn is - as nab054371 is trying to get the qmgr to segment messages to FIT into the queue...

Message segmentation is either explicitly done by the application (not the case here) OR by the queue manager when sending message segments from one qmgr to another qmgr via channels.
Are the two applications, the one that puts a message to the queue and the getting application, on different qmgrs? across channels?
Am I missing something? |

nab054371 is trying to write code to have the qmgr segment messages when PUTTING.
When trying to do this, with the code shown, a 2030 is resulting.
It is only *slightly* possible, in my mind, that any channel MaxMsgLns would be involved.

| Thanks for your response guys.Turns out I could not get segmentation to work off of dynamic queue,I guess the model queue does not have options to enable segmentation.I was able to get it to work on one of our static queues. |

| Check the QM (Queue Model) definition that the application opens. The QM has a max msg length attribute that must be as big as the message you intend to put to the resulting dynamic queue. |
