Hi All,
We are designing Broker Integration application, Broker V6 on Aix, Config Mgr win, and WAS V6 on aix.
We are in dilemma to use local queues for broker flows or Alias queues. For java integration we’ll be using Alias queues, but for broker I am confused. Can any buddy please give me pro’s and con’s of using Alias queues or local queue’s for Broker message flows.
Thanks

First tell us why you are using alias queues java integration ?
Why for you aliases are obvious but for broker you are confused ?
In my opinion aliases are useful for security management.

For Java integration, of course security point of view. But for Broker more from administration point of view. It will give flexibility to change the queue manager or the queues with out actually reconfiguring the queue names in the flow.
But i have not seen any document or any thing from IBM about it, and should we use it or not?
thanks

I guess I haven't tried, recently, to use an Alias queue as the source queue for an MQInput node. It works just fine for an MQOutput node, and I'd expect it to work for an MQInput node too. But you will need to restart the flow if you need to change the alias.

Thanks Jeff for your response.
One more question, does it impact on message processing? i.e. local queue vs alias queue for input and out put nodes in message flows. |

There will be, perhaps, a very small time difference to resolve the alias to a real queue. This will generally only happen once (each time you start the flow) for the MQInput node, and infrequently for the MQOutput node.
If you can actually measure that difference, then you've got a very good handle on your monitoring and you have very stringent performance requirements....
Switching from ALIAS to non-alias queues is about the last thing I'd tune if I had performance issues.
