Hi,
How can i publish to a remote queue manager on IIB without jms?

If i use a queue alias the message is going allways to the root of topic because i cannot select the topic string.

Any idea?
Thanks

No but you can create a topic object with the corresponding topic string and reference that topic object in the alias queue.

But if i configure the alias queue to send the messages to the topic what will happen is that the messages will arrive to the root of topic because the queue alias will make a PUT instead of a PUB.

I'm wrong? If so, how can i configure the queue alias to put the message into a specific topic string?

If i have this topic:

define TOPIC(DEPSUB1) TOPICSTR('DEPARTMENT/A/SUBJECT1')

Should i configure the queue alias with the topic name + topic string? Or just with topic string? like:

DEFINE QALIAS (MY.ALIAS.QUEUE) TARGET (DEPARTMENT/A/SUBJECT1)

Thanks for your help.

The target cannot be a topic string. it has to be a topic object. in your example DEPSUB1.

Sure, so how can i specify the topic string if i can only set the target to the topic object?

Thanks

You have a topic defined like this:-
Code:
DEFINE TOPIC(DEPSUB1) TOPICSTR('DEPARTMENT/A/SUBJECT1')

and you want to access it using an alias queue, so you create an alias queue like this:-
Code:
DEFINE QALIAS(MY.ALIAS.QUEUE) TARGTYPE(TOPIC) TARGET(DEPSUB1)

Please note the important TARGTYPE(TOPIC) attribute on this alias queue definition.

Now if an application does an MQPUT to the alias queue MY.ALIAS.QUEUE, it will result in a publish to the topic string 'DEPARTMENT/A/SUBJECT1'

Cheers,
Morag
