I have multiple application nodes running on the same machine. Right now I am using Jgroups with UDP Multicast and facing multiple issues with cluster performance. Found that the property mcast_port is same for all the application nodes. so was trying to change it. I have tried using following properties to change the port to 7771 in local.properties and none of them is getting picked by Hybris. It always picks the default port 7600 and starts using it.
cluster.broadcast.method.jgroups.udp.mcast_port=7771 hybris.jgroups.mcast_port=7771 cluster.broadcast.method.udp.port=7771
