SESSION AFFINITY QUESTIONS (Doc ID 1076512.1)

Goal

It appears that the Oracle Enterprise Taxation and Policy Management (ETM) Web application generates a session object for a session. The result of generating a session object (as it is called in WebSphere at least) is Session Affinity. The result of Session Affinity is that all requests for the duration of a session will be handled by one and the same applicationserver instance in the applicationserver cluster. This behaviour is somehow contradictory to ETM being a stateless application.

The questions are:
- why the session object is generated,
- for what is it used, and is its use mandatory for the validity/consistency of the session,
- what would be the impact if we break the session affinity, so requests for one session would be handled by any applicationserver instance in the cluster (thus optimizing balancing)?
