| I'm using Aggregator Node and setting the time out in control node to 30 secs. When I deploy the Message Flows both request and response I see that after every 30 secs aggregator reply times out even without any message being put in the request queues. Is this how the Aggregator Node behaves or there is some way to control this? I want my message flow to start after a message is first put in the request fanout queue. |

That is not the way is supposed to work. I´ve been using the aggregator nodes for a long time and I never got that problem.
Make sure you don´t have any input queue associated with any output node in other message flows.

[quote="Gopal"] I didnt understand Lilio when u said that make sure u dont have any input queue associated with any output modes in other message flows. In fact the queues that I'm using for my message flow are being used only in this message flow. These queues are not being used by anyone.
Following is my message flow
Request Flow Q1
QIN--AggrContrl--Q2
CtrlQ
ResponseFlow
CtrlQ-|
RepQ--AggrReply-out----------QOUT
-timeout--processing-TimeOutQ
I have set Timeout in aggrcontrol as 30 secs. When I Deploy these 2 in my execution grp for every 30 secs I see AggrReply timing out without even any message being put in QIN.
Try this same code. Put some sample XML data and you should be able to reproduce the problem. |

Can you give me the details for the queues (Q1, QIN, Q2, CtrlQ, RepQ, QOUT and TimeOutQ) ?
What are you doing with the request messages?
Where is your Aggregate Request node?

Request Flow
Q1---aggrReqQ1
QIN--AggrContrl--Q2---aggrReqQ2
CtrlQ
For Q1 and Q2 reply queue is sent RepQ.
ResponseFlow
CtrlQ-|
RepQ--AggrReply-out----------QOUT
-timeout--processing-TimeOutQ.
I have followed the same procedure as given WMQI Documentation Chapter 6 Aggregator Nodes.
Request Messages I'm sending to different host system queues which will reply back in RepQ. I aggregate this reply and put in QOUT and on time out put in TimeOutQ.
Q1, Q2 - Request Queues
CtrlQ - Control Queue
RepQ - Reply Queue which gets the responses from the Q1, Q2.
TimeOutQ - is timeout queue for aggrReply timeout terminal
QOUT - is output queue for aggrReply out terminal
What is surprising here is the after a specific time interval set in the aggrCtrl node aggrReply starts timing out periodically after specified time in aggrCtrl node. I wanted to make sure that this behaviour is actual behaviour of AggrNode. Or it is something strange and can be controlled? |

I´m sure that this is not the correct way to work for the aggregator nodes.
You could also take a look to the redbook "Developing solutions in WebSphere MQ Integrator" where you could find a chapter covering the aggregator nodes.
Cheers,

I have found the solution to this. Basically the problem was the previously deployed message flow used to run and that was causing the problem.
Anyway thanks for your suggestions and making me to find out the solution. |
