Hi
I use an "aggregate reply" node (WMQI 2.1) to aggregate some reponses. In out flow, if i have an exception, the aggregate never finishes. I always have message in timeout and catch terminals. The problem, i think, comes from the database, because i always have lines in baggregate table. if i delete manually records, the problem is stopped.
At what time the the records are deleted ??
Is it a bug in aggregate node ??
Thanks for your help.

The database records relating to an aggregation are deleted by the AggregateReply node after sending out the aggregated reply message.
The fan-out and fan-in flows should be executed within a transaction, so that in an error case (i.e. an exception is thrown) the whole unit of work is backed out and the aggregation is left in a consistent state.
I would recommend that you should firstly find out why an exception is being thrown (look in your event log) and correct that. There should be some useful log information to help you Also, make sure that the input nodes and output nodes have the correct transactionality setting (set to 'Yes') |

Thanks for informations.
But how in the message i can find info about transactional mode ?
In my message flow i define transactional mode but perhaps the problem is with MQ client developement which posts the message. |

| The transactionality of the MQ Client which does the original MQPUT is not relevant. It is only relevant how WMQI does the MQGET, and that is determined by your transactionality settings on the MQInput and MQOutput nodes. |
