MQeStoreAndForwardQueues have a property identifying their set of target queue managers (Queue_QMgrNameList).
In the case of the Store Queue MBean, there is no ForwardToQMgr. The sole purpose of this queue is to store messages for the queues in its DestinationQMgrList.
The Forward Queue MBean instance, by contrast, has a ForwardToQMgr as well as a DestinationQMgrList. Thus it has both the forward and store capabilities of the MQeStoreAndForwardQueue while the Store Queue just has the store capability.
This division of functionality between queue MBean representations is intended to simplify the roles of the queues in question. The Store Queue is, in effect, a "storing" queue without the "forwarding" capacity of the Forward Queue.
