When using the SERVER AFFINITY setting, how is the distribution of the JMS messages done every time a message is queued to a JMS DISTRIBUTED QUEUE?
"Server Affinity" is a concept widely used in distributed systems. In broad terms, it is a mechanism where the processing of client requests if forced to stick to a specific machine, not allowing any further processing linked to that request to be instatiated in (or moved to) any other machine but the one who started the chain. This generally means also the information for the request only lives and resides on the specific server, and is not distributed to other machines (which means, among other things, better performance).
