In order to achieve the load balancing in queue manaer cluster, the applicaiton has to open the queue as MQOO_BIND_NOT_FIXED but do we need to setup the parameter DEFBIND to NOTFIXED in the cluster queue definition?
Also does it make any sense to set DEFBIND to NOTFIXED in case of remote queue? |

DEFBIND is 'Default Binding'. It's not necessary to set it to BIND_NOT_FIXED.
It's a good idea, though, to make sure that applications don't bind on open if they specify BIND_AS_QDEF.
That way, you know that the only way they can BIND_ON_OPEN is if they explictly specify BIND_ON_OPEN.

jeevan,
Top tip... When it comes to descriptions of object attributes and application programming options, a good place to start is the WMQ infocenter. See http://publib.boulder.ibm.com/infocenter/wmqv6/v6r0/index.jsp
The infocenter has a search function too, and in this case entering something like "MQOO_BIND_NOT_FIXED" should get you going.
Cheers,
Ian |

I know that. What i am trying to do is, whether I can test load balancing ( sending the message to different queue manager) using amqsput utility. I am not able to do it. So, I am wondering whether I missed something in setting up.
Can the load balancing be tested only with mq app or is there any utility I can use to test this?
thanks a lot |

Read the cluster manual  and put on a gateway qmgr. This will demonstrate load balancing.
In V6 you can put to a qmgr where the queue is hosted and still load balance but you MUST change one of the clustered parameters of that queue. By default the behavior is like in V5.3.
On top of this make sure you either set the qmgr to blank on a put1 or (using amqput tool) you use a qmgr alias for the cluster. Otherwise I do not see how you are going to get the desired load balancing effect in V6 without a gateway qmgr.
Enjoy

Jeff, MQ Admin,
Thanks you for your valuable input. I am asking this way because I have to step in a project just a week beofore it goes onto production. The client does not have mq expertise. Whoever has done the setup, has not left good documentation. The client is so worried, they dun like to touch anything now. I have to help them if they run into problem in this situation.
One last questions. What about the queue manager setup in queue connection factory in AS ? does it require to leave blank or can have value? I understand it has to leave blank in put call/put1 call in application.
Thank you a lot, |

You need to specify the QMGR name in the QueueConnectionFactory
On the Queue property, you need to leave it blank. |
