Re: Specify hostname upon DB connect
Hello,
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
effect:
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?
Regards,
Tarlika
