Hi Wolf ,
Thank you for your answers .
Could you kindly elaborate on point 3 . I understand that the multicast-port is used for multicast messages which form the foundations of the cluster , but am still unclear as to what we need the port 55200 for .
Also a few further add-on questions :-
4> Let us say that I have 2 clusters running with different multicast address + port combinations ... in case the cluster names are the same , will there be an issue ?
5> The cluster names are the same as the names ( output of the hostname command ... assuming a Unix box ) of the first node starting the cluster right ?
6> Assuming that running more than 1 JBOSS cluster on the same network is a common requirement , what are the default methods that are generally used to guarantee unique multicast-address + port combinations ?
In our case we were thinking about setting the last 3 octets of the multicast address as the same as the last 3 octets of the IP address of the first node of the cluster ( assuming locally assignable multicast addresses belong to the range 239.0.0.0 - 239.255.255.255 ) .
