I reached out to the node-mysql folks on their Github page and got some firm answers. MySQL does indeed prune idle connections.

To complete the accepted answer, if you want the default user agent use System.getProperty(“http.agent”) client.getParams().setParameter(CoreProtocolPNames.USER_AGENT, System.getProperty(“http.agent”));
Relative path: ConnectionString = “Data Source=|DataDirectory|\Database.sdf”; Modifying DataDirectory as executable’s path: string executable = System.Reflection.Assembly.GetExecutingAssembly().Location; string path = (System.IO.Path.GetDirectoryName(executable)); AppDomain.CurrentDomain.SetData(“DataDirectory”, path);
RMI generally won’t work over a firewall, since it uses unpredictable ports (it starts off on 1099, and then runs off with a random port after that). In these situations, you generally need to resort to tunnelling RMI over HTTP, which is described well here.
