Ok. I misunderstood. That was just the first thing that came to mind. I don't know about this as I haven't done it before.

Andrew, that will indeed connect them, but it won't start the application on the dynamically added node if all the rest go down. That is what this mechanism does. I do not know how to do it. I've been wondering about it myself.

You can start the 4th node and do a net_kernel:connect to one of the other nodes. Just make sure that the cookies are the same on all nodes.

HI:
I have a distrbuted system  using erlang's distributed application mechanism.It firstly ran on 3 nodes with the config file like this:
 
[{kernel,
  [{distributed, [{myapp, 5000, [, {, }]}]},
   {sync_nodes_mandatory, [, ]},
   {sync_nodes_timeout, 5000}
  ]
}
].
 
Now I want to  add one more node to  the system  .How can I do this using erlang's distributed applicaiton mechanism? Do I have to edit the config file on all 3 nodes to add the 4th node and restart all of them? 
 
Thanks .
