Exactly what open-options and put-options does the app specify? Please be specific.

Yes; and you've already posted that the queue has DEFBIND(OPEN).
So I stand by my previous incredulity. How can you have correctly determined that the messages are being put with a binding of OPEN and post here asking why the load balancing isn't working? Given all the posts on this thread about the binding, why are we still talking about this?

Just to be absolutely clear.
Change the DEFBIND(OPEN) to DEFBIND(NOTFIXED) and then *think*. |

| Thanks. I was wondering how the balancing was working fine for batch when the DEFBIND(OPEN) was set? Anyways I will try changing the options and see if it fixes. |

Does the batch also go through the same route in the DataPower? The same route into the cluster? So at no point is there any oppertunity for the binding to be specifically selected rather than left to default?

| It goes through the same path. There is an alias queue that is different in the path. I will check and see how it is set. |

There might be a reason for this. Also verify if the batch run has message affinity...(not uncommon)

If there's a different alias queue in use, it's not the same path.

Also, again.
If you send a single message to a cluster queue, and another application is sending many many messages to a different cluster queue from the same queue manager, this can make cause a big impact on how the single message is routed through the cluster. |

Not sure I understood. Does this mean I need to have separate queue managers with different clusters one for batch and one for online?  |

No.
Let's say one app uses a QAlias with BIND_ON_OPEN, and another app uses a different QA (or QR or QL) with BIND_NOT_FIXED, you should expect different results, shouldn't you?
It is the definition MQOPENed that sets the BIND (and other) option.

And, again, the amount of traffic going from one queue manager to another has a significant effect on how cluster objects are load-balanced from that same queue manager. |

| Thanks. It appears to be an issue with one of the queue settings which was set as "OPEN" instead of "NOT_FIXED". Got it fixed. Thanks again. |
