Hi All,
I have a simple MDB program which receives a message from a queue configured in IBM MQ Series 5.3.
Using a client program i am sending a message to the Queue, and MDB reading the same.
In order to try the Message Redelivery option i am raising an exception in the MDB and i am expecting the message to move back to the error queue configured using backout queue. But this scenario is not working properly, MDB doing a rollback but messages are not being moved to a error queue.
Am i missing any configuration here. Ready to provide the same code.
Kindly suggest me on this.
Thanks in advance
Prasanna. |

Did you set the MDB retry > queue BOTHRESH > 0 ?
Which environment are you running WAS or any other J2EE app server?
Enjoy

Is the reading of the message in a seperate LUW ?
what is happening to the message when an exception happens ? does it go back to the source q ? does it dissapear ?
have you specified backout queue on the source queue? what is the backout threshold set on the source queue ?

The message getting disappered from the queue, it is not in the Inbound queue as well as error queue.

DEFINE QLOCAL(HUB_TO_JMS.SAPPHIRE) REPLACE +
DEFPSIST(YES) +
BOQNAME(HUB_TO_JMS.SAPPHIRE.ERROR) +
HARDENBO +
BOTHRESH(3)
DEFINE QLOCAL(HUB_TO_JMS.SAPPHIRE.ERROR) REPLACE +
DEFPSIST(YES)
Kindly let me know if you need any further inputs.
Thanks and Regards

You are not using WebSphere Application Server.
I guess you will have to write your own backout logic...
Enjoy
