Hi Sebastian,

Thanks for your answer,I understand how the cluster mode works, in fact I have a cluster with two nodes in the same machine, each node was started with clustered.sh, however,when I start other node in a different machine this the node could not be connected with the others nodes. I have Jgroups configuration by default in the clustered.xml but nodes or clusters in different computers can´t connect,

best regards,

this is my clustered.xml, i'm using this file for the nodes  in differents machines.

Hi Sebastian,

Thank you so much, the problem was the networks policy for the connection with UDP protocol, once fixed, the nodes between differents machines can communicate.
