Hello All,
I have to override MQGet node Queue name property in while loop for each message.
I am geting exceptions can you please tell me how to go ahead.
Here is the existing code which I need to work with
WHILE ALLMessageRead=FALSE and curQdepth >0 and Index<batchsize DO
PROPAGATE to TERMINAL 'out' ;
END WHILE
with below approach I was trying and propagated to out, it did not work.
SET OutputLocalEnvironement.MQ.GET.QueueName = queueName;
queueName I provide using external variable UDP.
lets say there are 4 message to loop through which means it needs to send one by one all to one queue.
it only propagate 1 message to the overridden queue and next propagate it gives an exception "failed to open queue"
Failed to open queue is dummy queue I have provided in MQGet node property.
the outlocalenvironment is geting swipped off when it comes back to propagate next message.
what is solution to make sure all 4 message is commited to downstream queue?
Thanks
PK

It did not work is not precise. What exception(s) were thrown?

No need to look at queue depth, as MQ internals will return r/c 2033 NO_MSG_AVAILABLE at next Get call when there are no messages in the input queue.

you are not geting my question my target queue should have 4 message when source wants to propagate 4 from its source.
it is only propagating 1 message and 3 remains in source queue.
which means while propagation the destination queue which I have overriden is
reseted to node property which is a dummy value(dummy queue name)
obviously it will says can not open queue in the exception header.
not sure why you answered me with mqrc code 2033
thanks

Will this app only and always deal with 4 messages? If more/less, will you need to modify your app to know how many messages?

You need to overwrite the local environment variable for each message!

Why are you looking at curQdepth?
