Hi,
I am trying to put messages into the queues specified in Destination List. ( say 3 queues ). Suppose one of the queue is put inhibited, the messages are put into the other 2 queues. and the exception list is raised.
a. I would like to know if we can put the messages into all the 3 queues in transaction. So, if there a problem in one, all messages will be rolled back or would be comminted. following is the ESQL code used :
SET OutputLocalEnvironment.Destination.MQ.DestinationData[1].queueManagerName = 'QM1';
SET OutputLocalEnvironment.Destination.MQ.DestinationData[1].queueName = 'OUT1';
SET OutputLocalEnvironment.Destination.MQ.DestinationData[2].queueManagerName = 'QM1';
SET OutputLocalEnvironment.Destination.MQ.DestinationData[2].queueName = 'OUT2';
SET OutputLocalEnvironment.Destination.MQ.DestinationData[3].queueManagerName = 'QM1';
SET OutputLocalEnvironment.Destination.MQ.DestinationData[3].queueName = 'OUT3';
b. If this rqmt is not pssbl thro' Destination List, is there any other alternative to acheive this goal in MB?
Appreciate your valuable suggestions.
Thanks
S Hemendr |

You know, the helps that come with the product are pretty good.
I'd start with the Transaction Mode of the Input and Ouptut nodes if I were you.
Cheers,

Eddie - Thx for the reply. Agreed that help material provides much valuable suggestion. and based on that I have set the transaction mode as YES in both input and output, which means transaction will commit (i.e., message are put in local queues) after the flow is successfully completed. However with regard to destination list this does not seems hold good. As the number of apllication to consume the message are static, we are not considering pub/sub. So, if any of you can share you experience with destination list, it would be a great help for us. looking forward to hear something on this front ...

If you set the transaction mode of the MQOutput node to Yes, then it will always commit each put.
Also, the MQOutput node does have an output terminal.

You could also take a look at this if you ever want to change the behaviour of the way transactionality works with Destination Lists.
Cheers,
