| Use MQGet node in a 'propagate' loop. |

Hi Tony,
Thanks for your response......I know how to send one I/P message to multiple destinations with Propagate but its reverse so can you please suggest me how can i use the MQGET along with Propaget in this case. Thanks for your time....
Thanks,
Bindu. |

Hi,
Thanks for your response......I am little bit confused about using the propagate statement for this scenario because i know how to use for single request sending to multiple destinations......can you please help me for multiple requests merging together as a single message and sending to destination....means 4 messages from I/P queue and then by using these 4 messages i need to prepare one message and send it to destination. Thanks in advance.
Thanks,
Bindu. |

MQGet node will only fetch one message at a time.
If you have a compute node upstream from an MQGet node, and that compute node executes a loop that calls PROPOGATE 10 times, then the MQGet node will fetch 10 messages.
Everything else is left as an exercise to the reader.

Hi Jeff,
Thanks for your quick response. If i use the propagate 10 times in compute node followed by the MQGet node then everytime propagate statement will send it to downsteams and clears the Output Message tree so that i cant able to use the previous message right. Is it possible to use the previous message along with this current message to generate the new output message. Please help me on this.
Thanks,
Bindu. |

Bindu,
Take a look at the v6 PROPAGATE documentation. There is now has an additional clause of DELETE that can be used to keep LocalEnvironment, ExceptionList and Message trees after each PROPAGATE. |

And even without the new options, it's always been possible to rebuild the output tree.

And if you're reading messages, using the MQGet from the same Queue as the input, you'd better make sure that you never start multiple copies of the Flow.
And the "loop" had better know how many messages to get, or some way of identifying which messages to get.
Cheers,

Hi All,
If i use the flow like below
MQGet Node -> Compute Node -> MQ O/P Node then its not able to deploy into excution group because of no Input terminal found in my flow then i changed my flow like below
MQ I/P Node -> Compute Node -> MQ O/PNode then its processing everymessage from I/P Node and able to propagate the message through Compute node but i am not able to store the data from the previous message while doing the transformation of second message. Any suggestions how can i design my flow & also ESQL Code in Compute node.
Thanks In advance.
Thanks,
Bindu. |

MQGet node cannot be used to start a msgFlow...you are supposed to start the flow with an MQInput node and then specify the queue for the MQGet...You could also trigger the flow using the Timer nodes incase you are not being provided with a flow triggering MQMessage.

PROPAGATE TO TERMINAL 'out' DELETE NONE....you were asked to read the manual, that would have taken you lesser time than posting here, and helped you understand all possible options of PROPAGATE.

Hi,
Thanks for all your time. Now i am able to send one request message to multiple destinations. I gone through MQGet doc ..... i will try to use that for clubbing 4 I/p messages into one o/p message (Still little bit doubt about the scenario...Little bit confusing...May be takes time to implement myself).
Thank you,
Bindu. |
