Hi folks,

Some guess since Torque is a service you would additionaly need:

+) Torque.shutdown()
+) Torque.initialize()

Subject: Re: Specify hostname upon DB connect

I tried to implement a reconfiguration of Torque at runtime following the advice Guy Galil
kindly provided below.

I just changed the URL but I didn't manage to get this change to take

Configuration config = Torque.getConfiguration(); config.setProperty(urlKey, newValue); Torque.setConfiguration(config);

What do I need to do to get the new config property value to take effect using Torque 3.1?


PS: I mistakenly sent this reply to the dev list a couple of days ago, 
sorry about that)
