Dear All,
I have the situation like we may apply the vertical (Multiple Processors) and
horizontal (Multiple machines) scalability to achieve load balancing for the EJB
components. Can any body explain how does the Container behaves in this
environment.
Like I may have clone of a EJB container running on an another processor or
machine. But What happens to multiple requests for the single Entity EJB. What I
need to set as the Transaction isolation level? (I think,
transaction_serializable will do that??) If I am using the WebSphere 3.0 and
Oracle DB and DB is common on another machine accessed by all cloned containers.
For example, the JNDI maps (Load balancing) one client to Container "a" and an
another client to Container "b". Now what I need to do in the ejbLoad (Select
for Update or Simple select + Transaction_serializable_isolation will work).
