Hello gurus,
I have configured MQ Server channel, queue and queue manager for max message length of 15194304 .
But still I am not able to send a 10 MB string from my java client to connecting to the MQ Server .
i did a lot of search in the forum, but i could not find anything which might help me resolve this.
Program does not even come up with any exception or error.
Any help is appreciated |

If no exceptions are thrown, how do you know that your are not able to send the message?

because i have access to MQ Explorer to view the queue and also my browse program verifies that smaller messages are put successfully. |

What is the largest message you can successfully send? 4meg?

I progressively tried till 4 mb , 6 mb , 9 mb , it works fine and i can see the message in the queue.
It fails somewhere between 9 and 10 mb when program does not come back with any exception after the put call .In the following segment i do not see the SOP "about to close".It takes me to finally loop to close the conneciton. No MQException is thrown
MQMessage mBuf = new MQMessage();
mBuf.clearMessage();
mBuf.correlationId = MQC.MQCI_NONE; // this acts as filter when you browse the queue!
mBuf.messageId = MQC.MQMI_NONE; // if MQMI not set, so everyone can use the queue
mBuf.originalLength = 44304;
mBuf.format = "MQSTR";
mBuf.messageFlags = MQC.MQMF_SEGMENTATION_ALLOWED;
System.out.println(" mBuf.originalLength " + mBuf.originalLength);
//mBuf.writeString(xml);
System.out.println("----------- message length is ------------" + xml.length());
mBuf.writeBytes(xml);
System.out.println("put message to queue");
myQueue.put(mBuf, pmo);
System.out.println("about to close"); |

Hi Bruce,
i think my problem is resolved. Your reply kind of made me think in a different direction .
I was wondering why my program will start failing in 10 mb when there is no setting anywhere which limits the message length to 10 mb . So i looked at the resource usage , obviously cpu utlization goes 100% on my windows and i was wondering if this has anything to do with OutOfMemory.But they i was stupid enough to believe that I will see a graceful outofmemory excpetion on my eclipse console. While running on debug mode i realise that somehow MQQueue class eats up the outofmemory exception and program exits.
I have increased the memory settings , and now i can process the full 10.1 MB file
Thanks for your help! |
