Hi all,
Flow 1:
TCPIP Srvr Input -> Do something -> MQ1
Flow 2:
MQ2 -> TCPIP Srvr Output
I have a scenario in which Client ( it is basically Java Util for now) will send message to TCP/IP Server. Then write that message to MQ. I have successfully implemeted this part.
Now I have another Util which will fetch msg from MQ1 and write it back to MQ2 after processing. This part is also working.
Then I need to fetch processed message from MQ2 and send it back to the Client who initiated the request. For that I tried using TCP/IP Srvr Output node, but I am getting exception. |

What exception? "Cheese Out Of Range"? "Insufficient Pixie Dust In Server"?
What version of WMB/IIB are you using?
What steps have you currently taken to troubleshoot apart from this cryptic posting?
What steps have you taken in Flow 2 to identify the initiating client apart from putting an output node at the end of the flow and assuming it will automagically work out what you mean?
(Which does require a large and constant supply of pixie dust, so you could have a resource problem)

 Really sorry the way I posted my query. Firstly I have changed my Flow as below
TCPIP Srv Inpt -> MQ Output -> MQ Get -> TCPIP Srv Output
I am working on IIB ver 9. Re-phrasing my scenario, Client sends message to socket where our IIB node (TCP/IP Srv Inpt) is listening. Then I write msg to output queue Q1. My MQ Get node is listening to another Queue Q2. I have another application which fetches message from Q1 process it and write to Q2. then MQ Get fetches that message and pass it to Srver Output node.
It is throwing below exception when TCP/IP Server Output node is trying to sendData

What setting do you have configured on your TCP Server input/output nodes on the Advanced tab?
Stick a trace node before the TCP Server output node and trace
${LocalEnvironment} and check it still has the connection ID in it. |

This will seriously reduce the amount of pixie dust needed by the output node

Very nice description.

How much time does this flow (including the response via WMQ of this other application) take to execute? What is the wait time of the TCP/IP client which sent the original request?

How is your Java client app coded? Hopefully you are leaving the socket open after you have sent the request right?
This error looks like the kind of thing you could get if the client closed the connection after sending the request message (Although I would have expected an error along the lines of 'connection closed') |
