I'm using MDB on WAS 4.0.2 and MQSeries 5.2
Each time I get a message in the MDB onMessage, I'm sending it to another queue.
When 'm running 5 or more MDB sessions, with heavy load, each MDB is trying to send a message to the queue and I get the following error:
| Code: |
javax.jms.JMSException: MQJMS2007: failed to send message to MQ queue

Thank you for the fast reply, I'll try it.
I still have another problem:
When working under high-load, There is a MessageFormatException Unable to deserialize object each time I try to get the object from the JMS message arrived.
How can the message be non-serielized if it passed the queue?
| Code: |
javax.jms.MessageFormatException: MQJMS1061: Unable to deserialize object
at com.ibm.jms.JMSMessage.newMessageFormatException(JMSMessage.java:4435)
at com.ibm.jms.JMSObjectMessage.getObject(JMSObjectMessage.java(Compiled Code))
at il.adamtech.fmk.pubsub.model.QueueListener.run(QueueListener.java:113)
at java.lang.Thread.run(Thread.java:498)
java.io.StreamCorruptedException: InputStream does not contain a serialized object
at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java(Compiled Code))
at java.io.ObjectInputStream.<init>(ObjectInputStream.java(Compiled Code))
at com.ibm.jms.MQObjectInputStream.<init>(MQObjectInputStream.java(Compiled Code))

| Do you only get the unable to deserialize object under heavy load or all of the time? I thought that there was a bug in the JMS regarding trying to deserialize objects when running under WAS. I'd suggest getting the latest MA88 if you don't already have it because I thought it fixed the problem. |

Hi:
I don't get this exception all of the time, but from time to time.
I downloaded and checked the MA88 and I have the latest version instaled on my WAS (running on AIX) so this is something else.
Any other help? |

From Appendix A of the MQSeries Application Programming Reference manual:
| Quote: |
MQRC_RFH_ERROR (2334, X'091E')
Explanation: The message contains an MQRFH structure, but the structure is not valid.
Completion Code: MQCC_FAILED
Programmer Response: Modify the application that generated the message to ensure that it places a valid MQRFH structure in the message data. |
later

Read that, but thanks!
Any way, it seems that since I'm running a client over NT and a server over AIX, The problem of serialization was CharSetID problem. |
