Hi all
I had a flow which when running in Local m/c is working fine but when i run the same flow in staging with the same i/p msg for testing it is going to backout queue.
wat cud be the reason
when does a msg goes to the back out queue.
In the flow we did not mention any logic for sending the msg to backout queue
Is there anything that i am missing here |

Messages will go onto the backout queue if the backout count > q's backout threshold and you have nothing connected to the failure terminal of the MQInput node. Read the details of the MQInput node in the WMB Infocenter help (at http://publib.boulder.ibm.com/infocenter/wmbhelp/v6r1m0/index.jsp) - do a search for MQInput and read on...

Hi
In my case when i redeploy the bar file in the testing env, it is working fine for the first time again when we try to test it for other i/p msg it is going to backout queue..
I read about the Mq input node in the help and when i tried to change the BO threshold count from 0 to 20 the first 20 msg goes to the error without showing any error (only the msg is going) and the other msg goes to the Backout queue...
If i redeploy the bar files again the same process is repeating..
Pls suggest me what is going worng here.... |

Only the message will get put to the backout queue, not the exception information. I would suggest that you trace the exceptionlist in a trace node connected to MQInput's catch terminal. That way it will tell you what is causing the exception.
Remember to hang a throw node off the trace node, otherwise your exceptionlist will be traced and the flow will complete successfully, discarding your message. The throw node will force the MQInput node to rollback (an exception occurred during propagation to the catch terminal).

hi jsware,
Thanks for the reply ..In my case i have an error handling subflow coneected to the catch terminal of the mqinput node ..WE had recently observed that none of the flow in this env is running ,every flow is going to the backoutq when we run the flow..
Could there be any problem with the MB configuration or the QM configurations.we have broker running on AIX and Configmgr running on windows..both the QM's are linked with channels and all the channels are in running state. |
