Class Invoker

java.lang.Object
  org.opennms.netmgt.vmmgr.Invoker

public class Invoker
extends Object

The Manager is reponsible for launching/starting all services in the VM that it is started for. The Manager operates in two modes, normal and server

normal mode: In the normal mode, the Manager starts all services configured for its VM in the service-configuration.xml and starts listening for control events on the 'control-broadcast' JMS topic for stop control messages for itself

server mode: In the server mode, the Manager starts up and listens on the 'control-broadcast' JMS topic for 'start' control messages for services in its VM and a stop control messge for itself. When a start for a service is received, it launches only that service and sends a successful 'running' or an 'error' response to the Controller

Note: The Manager is NOT intelligent - if it receives a stop control event, it will exit - does not check to see if the services its started are all stopped
