Dear All,
I have two machines, Aquila
and Lupus, and am trying to
keep the session alive on failover. I believe I
have
set them both up in a cluster. When one machine fails,
the requests
are correctly routed by the load balancer
to the other machine, but the
session variables are not
there. I am using the /servlet/SessionServlet to
test
this. Can anyone help? Below is the output from various
command lines
and also attached xml config files. These
are the only ones I have changed.
If any more info is
required please ask
Thanks in advance...
In
this example I started the loadbalancer on Aquila,
and the OC4J instances on
Aquila and Lupus, accessed the
SessionServlet and was routed to Lupus. I then
requested
that page a few times then killed the OC4J instance on
Lupus and
was routed to Aquila automatically but the
counter had
gone.
