I'm looking at the feasibility of sending mqseries messages from a source application to an IP Load Balancing Hardware Appliance. The appliance would have a virtual IP address. This appliance would then distribute the messages to servers in a cluster. This type of device is popular for distributing http traffic to a Web Server Farm.

My alternative is to use MQSeries Clusters but management wants to utilize this expensive hardware being used for Web Servers.

I can't conceptualize how this would work with channel definitions. Does anyone have experience with this kind of scenario? Does MQSeries have any facilities that support this concept?

I think this might work for MQ client connections to MQ Servers, however you need to configure the load balancer to ensure that subsequent connections from a given client IP address are sent to the same server (I think this is called persistent sessions, or sticky ports).

To be honest, you might as well just select a MQ Server from a list at random and connect to it (re-trying if not available).

If you were trying to load balance MQ Server to MQ Server connections then I think that this would not work, unless multiple queue managers had the same name.

I would try to convince MGMT to save the companies money and use clustering
