Hi, everybody! i have a problem, can you help me?
now, I have a SOAPAsyncRequest flow, like this:
Flow1: MQInput->Compute->SOAPAsyncRequest
and another SOAPAsyncResponse flow:
Flow2: SOAPAsyncRequest->Compute->MQOutput
Can I deploy these two flows in two diferent execution group?
If can, should I do some specific operations about the Nodes? |

My guess is, you want to correlate the MQInput and MQOutput with the SOAP Async call in the middle.
Look up the aggregation pattern.

it will cause Exception of cannot find the response!
so I think it can not be done like this! |

The aggregation pattern is not for the SOAP call, but for correlating the MQInput and MQOutput... as you have the SOAP Async call in the middle...

My guess is he wants this question answered - and what he has suggested is a pattern documented in the Toolkit help, without Aggregation.
Note the second flow should start with SOAPAsynchResponse node - the post is wrong.
http://www.mqseries.net/phpBB2/viewtopic.php?t=58799&sid=4904922893b91e5f7be2e8009dc78499
says both flows should be in the same EG.
Note it is much easier to support code that works together, by having it deployed together, imho. |

The Async Call won't necessarily complete.
The asyc request will be sent out by one HTTP engine on one HTTP port, and the response will be expected at a different HTTP engine at a different HTTP port.
There should be clear documentation on whether or not you can gather AsyncResponses in a different ExecutionGroup than the AsyncRequest was made from.
If there is not clear documentation, please open a PMR to get the answer and make sure that the documentation will get updated as well. |
