HI friends,
In the message flow with MQinput node, compute node and MQoutput node.
when i put a msg to mq-input queue node---compute node--mq-output node.
the message is coming to mq-output node but i cannot retrieve the msg.
and also i cannot clear the messages in this node.(when i tried it is saying that "queue is in use, wait for some time and try again")
I HAVE TO STOP QMGR AND THE SERVICES OF MQSI, THEN I CANNOT SEE ANY MESSAGES IN MQ OUTPUT QUEUE.
can any body whats happening...??????
thanks. |

| Could you post what you are doing in the compute node. |

What do you have connected to the failure terminal of the MQInput node?

Hi Lash,
Pls check for the following,
1) Once you put a msg in i/p queue were you able to see any increase in message count of o/p queue? If so, check the GET MESSAGES property of o/p queue. If it is set to INHIBITED you will not be able to retrive messages. Set it to ALLOWED.
2) If you were not able to clear messages, try mqsireload <broker name> , which will help you to release all the objects that are tied with the message flows deployed in the broker.
3) Are the messages NON PERSISTENT? If yes, you will not see them after you restart your qmgr.
Pranava. |

I believe this is what is happening
a) You are using some tool (like MQSeries Explorer) to put a message on the input queue and this tool is putting a non-Persistent message on the queue.
b) After the message is processed successfully you are able to see the message on the output queue (you confirmed this in your post?).
c) You tried to clean the message using some tool (let's say MQSeries Explorer) and its giving you an error "queue is in use, wait for some time and try again". This means the output open count for that queue is "1" and the tool (MQ Explorer) cannot clear the messages from the queue in such case. Use some other utility like amqsget[c] to clean the message.
d) When you restart the queue manager, all non-persistent messages are lost!

I used amqsget to get the message out of MQoutput queue, but no use.
i tried to clear the queue from command line, but no use..
i tried to clear the queue from mqexplorer also, but no use...
but if if put the message to mq input queue it is taking and showing in output queue also... but i cannot take the message from output queue.
only way i could clear the queue is by stopting the services, and qmgr. and again restaring the services.
and as far as in compute node is concerned...
SET outputroot.xml.request.country = 'UK'
above small code if i use also it is showing the same results....
 ??????????
thanks... |

It seems the problem is something else then. Is your message flow looping? Try this,
Disconnect your MQInput's catch and failure terminal. Simply attach two MQOutput nodes, one to catch terminal and one to failure terminal. You can define two queues called CATCHQ and FAILQ. Attach a trace node to the Catch terminal of MQInput node and print ${ExceptionList}. Configure the node to write the trace output to some file. Now run your message flow and post the contents of Exceptionlist here.
Your message flow should look like this,
MQInput(out)->Compute1(out)->MQOutput (output queue).
MQInput(catch)->Trace->MQOutput (catchq)
MQInput(failure)->MQOutput (failq)
Thanks,
Kiran
