Erlang: specifying a working directory for mnesia?
原标题:

How do I specify a working directory for mnesia without resorting to passing the "dir" parameter on the command-line?

In other words, can I specify a "working directory" for mnesia just before calling `mnesia:start() ?

最佳回答

application:set_env(mnesia, dir, Dir).

Besides the method call mentioned in other responses here you can also specify this in a system configuration file or .app file specified with the -config parameter. See http://erlang.org/doc/design_principles/applications.html#id2270704 for more information. This allows you keep the configuration seperate from the code and avoid a lot of command line flags.
