| Are their any implications while using Clusterded Broker Qm's for load balancing? |

- What do you mean by "implication"?
- Does it work?
- Oh... yes, it does!

Probably but it depends on exactly what your environment looks like and what you are doing wit hthe broker.

sry for not being specific with the question .
we are setting up a environment which have two active brokers having their qmanagers in cluster and with same flows deployed in both of them.
Our intention is to provide high avalability for the applications that are using brokers via mq cluster queue concept.
So are their be any constraints from the application prespective to make use of the clustered broker setup.
Will their any scenarios( apart from segmented and grouping) in which the Applications should not keep their messages in a clustered Queue( with out knowing which instance of queue its message will be routed)? |

This is a bad idea. Using WMQ clusters to provide HA (and why you shouldn't) has been discussed many, many times on this forum.

Applications should not keep their messages in a queue, clustered or not.

If your intend is to provide high ability you will have to bite the bullet of hardware HA or an MQ V7.0.1 only environment.
If your intent is to avoid a single point of failure, an MQ Cluster can help you with that.
Have fun

for active-2 application HA setup you need loadbalencer type of product which can route the requests messages to both application instances and not the Mq Cluster ...
Before implementing the HA You have to investigate the type of message flows...whthere there will be any affect on Db or application processing due to sequence number of messsages etc..
application can put messages in a Clusterd queue... but as your queue managers have clone Mq objects so you may need to bring out one queue out of MQ Cluster to avoid any sequence number related issue...
Overall there may be many scenarios...entirlely depends on your end to end setup for message flow...
