Hi,
I am trying to test the aggregation node. The flow is as follows :
MQ Input Node -> Agg Ctrl -> Compute1( out terminal) ...
-> Compute2 (out terminal) ...
-> Add MQMD Compue Node( Control Terminal)

The messages goes thro' Compute 1 and Compute 2. However it fails in 'Add MQMD Compue Node'. On digging deeper into I found that below exception is raised on the trace node, connected to failure of 'MQ Input Node'. please help me in resolving the issue. fyi, the message set is mrm based.

........................................................
(0x01000000):RecoverableException = (
(0x03000000):File = 'F:\build\S500_P\src\DataFlowEngine\ImbMqOutputNode.cpp'
(0x03000000):Line = 787
(0x03000000):Function = 'ImbMqOutputNode::evaluate'
(0x03000000):Type = 'ComIbmMQOutputNode'
(0x03000000):Name = 'com/wipro/test/Q_FanOut#FCMComposite_1_8'
(0x03000000):Label = 'com.wipro.test.Q_FanOut.MQOutput1'
(0x03000000):Text = 'Caught exception and rethrowing'
(0x03000000):Catalog = 'BIPv500'
(0x03000000):Severity = 3
(0x03000000):Number = 2230
(0x01000000):RecoverableException = (
(0x03000000):File = 'F:\build\S500_P\src\DataFlowEngine\AggregateNodes\ImbAggregateRequestNode.cpp'
(0x03000000):Line = 441
(0x03000000):Function = 'ImbAggregateRequestNode::writeDatabaseRecord'
(0x03000000):Type = 'ComIbmAggregateRequestNode'
(0x03000000):Name = 'com/wipro/test/Q_FanOut#FCMComposite_1_12'
(0x03000000):Label = 'com.wipro.test.Q_FanOut.AggregateRequest1'
(0x03000000):Text = 'Message id was not unique'
(0x03000000):Catalog = 'BIPv500'
(0x03000000):Severity = 3
(0x03000000):Number = 4420
)
)
)
--------------------------------
Thanks

The text states that the message ID associated with the control message is not unique. You are probably coping the MQMD across the board, and the aggregate flow needs unique message id's so that it can correlate the replies. You'll want to not copy the MQMD but instead build a new MQMD with the appropriate fields. The aggregation sample has a compute node that does this.
