Mnesia table events

[Dan Gudmundsson]

You only get events on the node where you called the subscribe command:

Node A                                                 Node B (A1)
							 
(
)1> mnesia:start().                               (
)1>  mnesia:start().
ok                                                    ok
(
)2> mnesia:change_config(extra_db_nodes, [
]).    
{ok,[
]}                                               
(
)3> mnesia:create_table(a,[{ram_copies,[
]}]).
{atomic,ok}                                                  
(
)4>                                               (
)3>  mnesia:subscribe({table, a}).
(
)4>                                               {
}
(
)4> mnesia:dirty_write({a,1,1}).                      
ok							 
(
)5> 					      (
)4> flush().
						      Shell got {mnesia_table_event,
                                                       {write,{a,1,1},{dirty,<127.32.0>}}}
