This one is a tricky design... not sure if anyone has attempted such. Here's the description...

In the same session we are sending multiple messages from one Client
(IOEngine) which is a non-WAS application to WAS application based on this rules:

1. First Message goes in any of WAS application (load-balanced).

2. The rest of the messages within the same session has to go to the same
WAS application that first messages went initially.

3. If in the middle of session, the peer WAS application dies, then we want
to re-route (load-balance) the message to any remaining running WAS
application

I have given this some thought and believe that a channel exit on the
svrconn channel could be used to register and de-register clients? Is that
possible - not sure if the channel creates and closes new instances of
itself for each client connection?!?

Any other suggestions?

Where does JMS come into this picture?

Are you using JMS to send messages to the WAS application?

Are you using WebSphere MQ as your JMS Provider?

Hi Jeff - yes the JMS api is used here and yes MQ is the JMS provider.

Why do you need to send more than one message to the same place?

You should probably set up WebSphere MQ Clustering and use a gateway queue manager for your Application to connect to.
