Hi,
I have developed a Java Application (using IBM MQJMS) that is putting a binary message onto a remote queue. I am getting this error for messages over 1MB in size. Have done a successful put of messages < 1MB.
| Code: |
Error Report:
MQJMS2007: failed to send message to MQ queue
com.ibm.mq.MQException: MQJE001: Completion Code 2, Reason 2030 |
I have checked the MAXMSGL parameters of the QMgrs, Local Qs, XMit Qs, Channels, DLQs and they are all set at 4MB or even higher.
Is there a size property for the queues that defaults at 1MB and needs to be explicitly raised in the code?
Uses IBM MQJMS API
| Code: |
// Create JMS Queue Connection Factory
com.ibm.mq.jms.MQQueueConnectionFactory qcfFactory;
qcfFactory = new MQQueueConnectionFactory();
qcfFactory.setTransportType(ConfigurationManager.getTransporttype());
qcfFactory.setHostName(ConfigurationManager.getHostname());
qcfFactory.setQueueManager(ConfigurationManager.getQManager());
/* If the transport type specified, is MQ Client transport, we need
the SVRCONN too
*/
if (ConfigurationManager.getTransporttype() == JMSC.MQJMS_TP_CLIENT_MQ_TCPIP)
qcfFactory.setChannel(ConfigurationManager.getChannel());
qConnection = qcfFactory.createQueueConnection();
qConnection.start();
session = qConnection.createQueueSession(boTransacted, Session.AUTO_ACKNOWLEDGE);
queue = session.createQueue(ConfigurationManager.getPutQName());
QueueSender qsender = session.createSender(queue);
....
....
qsender.send(mqMessage);
|
Would appreciate any hints. |

| Have you thought about your JVM heap size ? |

Thanks for looking into this, fjb_saper.
I had the impression that 1 MB was too low a value to start playing with the JVM heap size, but now that you say, I shall try that too.
I couldn't put a message 1,060,040 bytes long but succeeded for one that was 1,032,766 bytes long (just below 1 Meg) !!
Also, the linked Exception that I got was
com.ibm.mq.MQException: MQJE001: Completion Code 2, Reason 2030. If the JVM heap size was inadequate, I would expect the application to fail with a 'Out of memory error'
Update:
I was able to put the message successfully after raising the MAXMSGL on the queue. I found that while the message sat on the queue it was about 4 Meg in size (i.e. the Message on the queue was 4 times the size of the binary file that I loaded !!).
Is this what is expected? Am not sure. Any thoughts? |
