Not exactly. You could think of start/stop as thaw/freeze (their actual previous incarnation). The idea is that a “stop” terminates the application instance but maintains the configuration so that another instance can be started based on the same configuration. You probably could also think of the ZK config as the “class definition” and the actual launched instance as the “Object”. > > Thanks in advance, > > Manoj
