HI Experts ,
I want to understand the default behaviour of the JMS input node on Auto Acknowledging every message picked .
Is it the default behaviour of JMS Input node to Auto -acknowlede the JMS provider ?
How to find out which Acknowledgement mode is being used out of the below ?
- auto-acknowledge mode ??
- client-acknowledge mode ??
- dups-OK-acknowledge mode ?? |

Well it all depends whether you are using JMS1 or JMS2. But in a general way the decision is made when you create the JMS Session/Context.
Have fun

hi fjb,
Thanks for the prompt response.
I have jus created a message flow having JMS Input node connecting to the TIBCO EMS JMS provider. I have used point to point ( queue ) and able to connect and consume the messages .
I have not done any additional settings to node.
Now all i want to know is, if an acknowledgment is being sent back for every message being picked by the node ?
How can we monitor this ? what is the default behaviour ? |

The point as to when your message would be acknowledged depends on your transactional mode. However why would you expect the default behavior not to be autoacknowledge?
Each message represents its own transaction. So each message needs to be acknowledged individually... Have you verified what the options are for the node?

Hi Fjb,
Thanks for the response . The JMS Input Node Transaction mode has been set to "NO" so that means " its in non-transactional mode, so I understand that the receipt and acknowledgment of messages take place in one step" .
But currently , we are processing over 4 million messages per day , am afraid if this acknowledgment response to the JMS server for each message might create an unacceptable level of network traffic .
Before we decide onto go with Batch processing acknowledgment , jus want to know the easiest way to verify if an acknowledgment is being sent to each message received/processed , Can you pls help me to know the possible way ?
is enabling TCP trace the only way to verify this ? Any other alternative ? |

Open a PMR and ask for clarification. In the PMR you should also voice your performance concerns.
