imqcmd create dst -t q -n QUEUE_NAME
#configure the properties you want
imqcmd update dst -t q -n SUN_TEST -o "maxNumMsgs=10000" -o "useDMQ=false"
#check
imqcmd query dst -t q -n SUN_TEST
the kind of persistance need to be configure in the broker (look in properties file) there is one example with oracle I remember...
salut!
