This should work. Your linux boxes won't route multicast without the
entry in the routing table. I found this out while trying to debug
clustering with jboss and it fixed all my issues. Also make sure any
routers on your network will route multicast.

Since you are on RedHat you have to do these steps to enable multicast
on your machines:
assign an IP to a host
ifconfig eth0 multicast
route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0

Hi Filip,
are you running iptables firewall?
no. The servers are inside a hardware firewall.
that might also be blocking your multicast.
I do suggest you get a little utility that tests your multicast.
Can you suggest one?

Hi Filip,
here's my ifconfig-a:

Hi Filip,

ifconfig -a
multihomed simply means there is more than one network card
ping doesn't verify UDP and multicast.

Hi Filip,
I've just done:
route -n

Hi Filip,
you haven't mentioned anything about your environment. but my guess is that you might have linux and those boxes are multihomed. if
this is the case, its a little tricky to enable multicasting, there is a property "mcastBindAddr" to set the actual interface that
sends and receives the mul

Hi Filip,
the tomcat clustering code and the PersistentManager are not supposed to work
together.
does it matter if they're both switched on?
No members active in cluster group.
means that your multicast discovery isn't working
can you suggest a way to resolve this?

Simon
