Hi
Can I create an identical configuration of queue managers and channels with the same name in two different MQ Servers, both residing in the same network. Kindly let me know the implications (if any) of having the same MQ Object names.
Regards
Ajith |

Two different MQ servers it is possible to use it!
But it is recommended so that you have your MQ objects with unique names so that the ambiguity problems do not arise in future.
Also,you might face problems when bring in those objects into a clustered setup/ |

As long as you have NO intention of ever trying to communicate between the queue managers, you shouldn't have any problems. However, you'll probably find that the confusion of two separate but same queue managers is more trouble than it is worth. You might as well start with different names and avoid future problems.

It is a bad idea to have two queue managers with the same name in the same network.
It is not a bad idea to have channels or queues with the same names. In fact, for many reasons in many networks, it can be a good idea.

Yes you can but in most cases it is ill advised.
What would be the purpose of the second MQManager on a different server with the same name?
Would you want both to be running at the same time?
Would it serve your purpose better to create a new MQManager with different name and cluster them?

QMs are like kids in this regard. Yeah, technically you could name all your kids George, but is it worth it?
And if you ever want to cluster your QMs, absolutly you cannot do it.

Thanks a lot for all your responses.
Basically, we are trying to achieve failover in our MQ Environment.
Hence, we would like to configure the MQ objects with similar names in two different MQ servers. The Proposal is that we would have a load balancer outside our MQ Server. All the messages from the Outside MQ Server would first come to the Load balancer, then this would be forwarded to MQ Server A, where all the channels and MQ objects would be running. In case of any failure of MQ Objects in Server A, the load balancer would automatically redirect all the requests to Server B.
Here, the Load Balancer is only used as a failover object and not used for balancing any sort of loads between Server A and Server B. This is the reason why we are forced to go for similar object names. Kindly let me know your comments on our Approach.
Thanks
Ajith |

MQ Channels do not like to be load balanced by TCP/IP balancers.

Especially if the messages are persistant.

I was looking for a solution for the same problem in one of my recent posts. I was told that the best solution would be to have hardware cluster.
Take a look at my post @ http://www.mqseries.net/phpBB2/viewtopic.php?t=17583
I didn't get a chance to work on it as it was put on hold for now. Please let me know how it goes.
Thanks. |
