• Caution a queue name (JT819300) could have several queue_id (133, 114)

• Queues are activate by Activator in 'process' method
  by iteration over queuesMap
  

  .getWaitingQueues(resource.getMediaType());
  // getWaitingQueues will retrieve waiting queue from QueuesController.queuesMap
   while (waitingQueues.size() > 0)) {
     Queue bestQueue = QueuesController.getInstance().getBestQueue(resource, waitingQueues);
  
  

• For an activated queue name (JT819300), in memory , (I mean in queuesMap) you will have activated queue_id (e.g. 113) and created queue_id (e.g. 114),
  this may be surprising !
  (this will be done by Activator.activate(bestQueue);)

So in short term , in memory queuesMap (key = JT819300) can be activated, but in DB, queuue_id (113, 114) related to that queue name can be not all activated (Thank you very much for code clarity !!!)

• One more thing ...
  queuesMap if fiiled by Dispatcher (for sure), when calling addFilePositionOnTape() from submitRequest() (see QueuesController.create())
  But if Dispatcher fail for any reason, queuesMap will never be updated
  and obviously files never get staged !
  But why Dispatcher could get blocked ?
