Hi,
I have the (J2EE Blueprint) PetStore application clustered on two Orion
instances running on the same machine.
When I connect through the LoadBalancer, I can see my session state get
replicated across the two nodes. When I kill the primary node, the load
balancer automatically connects me to the secondary node and takes me
through the rest of the shopping cart experience, however any items I had in
my cart (ie. Session state!) aren't there anymore.
I know that for clustering to work, objects should be Serializable AND
placed in the session/servlet context for it to be replicated. So my *real*
questions are:
1) I haven't dived into the PetStore code - but is this a design issue with
the PetStore or do I need some configuration pointers?
2) Has ANYBODY got PetStore working properly in a Clustered environment
where you can kill the primary server and continue shopping (with your
existing cart) on the secondary node?
My Environment:Win2K, JDK 1.3, PetStore 1.1.2, Orion 1.4.5
NB: The SessionServlet example works FINE for me. When the primary goes
down, the secondary node picks up with the same counter number as before the
failure.
