| I am trying to install MQ with Distributed q manager; I am using a Content switch to load balance the messages to the MQ. I want to know if the IP based content switch will effictively perform load balancing...has this been tried out |

Usually load balancing is not done at IP level... Read the MQ Cluster manual about how to do load balancing

| Actually I want to know if I can do this without clustering the MQ channels. My MQ Server queue managers are on different hosts and my Front-end tool (having MQ Client embedded) connects to the MQ Servers through a content switch (intelligent router/IP sprayer) |

OK, let's get specific.
We need numbers/quantities.
What specifically do you want to load balance:
Connections to the qmgr? How many total? Across how many qmgrs? Average size of msgs?
The applications working off the load presented to them through MQ?
Let me refer you again to the cluster manual.

1) WMQ clusters queues not channels
2) Do a search through the forum - IP spraying technology has been discussed a few times. There are issues using WMQ channels over such things.

MQ 7.0's implementation of Clinet Channel Tables allows for load balancing of incoming MQ Client connections.
Apparently you can set an environment variable telling MQ to suppress those error messages from the constant pinging by the load balancer.
