Hi All,

Our flow looks like this

MQInput -> Compute -> MQGet -> Compute -> MQOutput

The message in the MQGet Queue has RFH2 headers. My MQ Get Node is configured like this :
Output Data Location : OutputRoot.MQRFH2.usr
Result data location : ResultRoot.MQRFH2.usr

My incoming message has the following message headers in it
1. Properties
2. MQMD
3. BLOB

After the message is got from the MQGet node, as per the intended behaviour MQRFH2 header gets appended to my OutputRoot.
Thus my outgoing message from the MQGet node has
1. Properties
2. MQMD
3. BLOB
4. MQRFH2

I am swapping the position of MQRFH2 and BLOB in the compute node after the MQGet.

I was wondering whether it would be possible to do the insert between the message headers within the MQGet node itself.

Thanks in Advance,
Harish

Create the MQRHF2 header before sending the message to MQGet node... and in that case the sequence ll be maintained.

Hi Akanksha,

Thanks for your input, but i wanted to know whether there might be a way to do this in the Node level itself rather than at the ESQL level.

AFAIK there isn't any way for MQGET node to know the sequence in which headers should be created......



you only need to maintain the sequence..
