Hi ,
I have a datapower device(XB60) recieving mesage from a client and writing the message on a queue . I have two queue managers in a cluster and the queue is a cluster queue .
Is there any way to use the feature of a cluster (cluster queue on 2 qmgrs) in the MQ back end .
All I can do now is create a MQ queue manager object which points to a specific queue manager , rather than just using the channel and writing it onto a queue . MQ queue manager groups does not give me the option of workload balancing , its like more of a failover option .
Thanks

Accept from the start I don't know Datapower from a hole in the ground.
But is there any way you could do what an application would do in this instance and point to a cluster alias to have the distribution done?
Or change Datapower in some way so it doesn't do a bind on open?

That is the option I am actually left with now .
Have a sort of a gateway with aliases poiting to the actual queues in the cluster to do the distribution .
Im trying to find out how the DP MQ client uses the MQ API's(not very explicitly given by IBM)
I thought Datapower being in the websphere suite should be very amicable to MQ as such . Or I may be missing a joint somewhere ...

I spent a whole 30 seconds with Google and you could start with checking the default binding value on the queue you're using. From this extensive research it looks like it's using the "value as queue defaults" settings for all of the attributes, and the default cluster binding is bind on open. So if it's not been changed on the target queue you could try changing that and seeing if that helps.
(This of course means I can now change my CV from "aware of Datapower" to "familiar with Datapower"  )
