| 10000 store registers are connecting to our 10 front end MQ Servers and all the 10 Queue Managers are in Cluster. Now we are asked to set up load balancer in between registers and MQ Servers. It would be very helpful if any one can guide me in setting up this. |

Th load balancer already exists since you have MQ CLUSTER topology..
how are your registers connecting to front end mq servers right now ??

| I know about cluster load balancing.....regsiters are connecting through server connection channels. |

your all 10 queue managers are already in cluster
have the application queue existing on multiple queue managers (for load balancing), ensure the stuff that queue bind is set to not fixed and localaddr is set any....
now all connecting applications(registers) would send the messages to various front end applications in round robin fashion...
is that what you were looking for??? if not then pls elaborate your requirement

I suspect the poster is looking for a way to distribute the 10,000 client connections across the 10 clustered servers using some kind of network IP balancing hardware.
But that's just a suspicion.

Akanksha,
All application queues have defbind set to Notfixed and i'm not asking about load balancing within MQ.
Vitor,
You are right. That's what i'm looking for. We are doing network segmentation as part of PCI requirement. So, we are asked to put load balancer and firewall between registers and MQ Servers. |

WMQ channels do not enjoy having their destinations switched while they're connected because the ends are syncronised. So if the hardware switches from one server to another the registers (which I'm assuming are clients) will have to handle the error and reconnect.
If you just want to distribute connections (i.e. 1000 on each server) you can use different client tables for the various groups. This also allows the registers to use alternative servers if their expected server is down.
