Could any one tell me how horizontal scaling works?
Suppose i have S1-->S2--->s3--->S4--->s5-->DBServer
Now if a client is on transaction and the session is active on the first
server .Now suudenly the S1 fails how does the session gets saved / propagated to S2 to take over or what is the way to handle this kind of failover w/c client won't get affteceted but the transaction would go safely
with session data.
Pls explain the config in perspective of Weblogic & Websphere & the concept.
