I am trying to read the remote Mnesia node using an Erlang command. I am using Ubuntu 14.04 and I am running Erlang 17 OTP. I tried to start my local Mnesia node by issuing

mnesia:start().

And then I tried to connect to remote node with 

mnesia.start([{extra_db_nodes, [:'abc@def.com']}]).

It returns true. Then I issue the mnesia:info(), however, it only returns the local Mnesia info. My question is how can I issue the Mnesia command to a remote node from my local node? I am wondering how I can get the Mnesia data of extra_db_nodes in my local node?

  • Is this a duplicate of http://stackoverflow.com/questions/29642263/how-elixir-can-read-remote-node-mnesia-table? – Onorio Catenacci Apr 15 '15 at 14:27
  • Sorry for the not clarity of my question , it is not duplicate of the question. For that question, I am asking the elixir way to access remote mnesia node. This question, I hope I can get how to use erlang command to access the remote mnesia node. – want_to_be_calm Apr 15 '15 at 14:47
  • Hi, am I asking an impossible solution? I think I can put in in simple, it is how to read remote node mnesia info from my node. Thanks – want_to_be_calm Apr 16 '15 at 02:45
  • You seem to be asking at least two different questions and neither one looks like your real underlying question. Do you want to know how to execute code on a remote node? Or are you asking how to distribute the database? Please try to rephrase your question as an actual problem you're trying to solve (like "I want to access the same piece of data on two machines"). – Nathaniel Waisbrot Apr 16 '15 at 11:48
