Runing an enhanced broker cluster with mysql store we see that autocreated queues are not removed from DST table when destination is supposed to be destroyed.
Calling a simple consumer on a nonexsiting queue creates the destination:
java -jar /tools/jms-tests/consumer.jar 3000 xx.xx.xx.xx 37676 testdel
We can see it exists:
imqcmd -b xx.xx.xx.xx:37676 -u admin -pw admin query dst -t q -n testdel
Destination Name Destination Type
testdel Queue
On the broker specified by:
Host Primary Port
xx.xx.xx.xx 37676

Successfully queried the destination.
After we get: Destroying auto-created destination testdel [Queue] inactive for 7200 seconds and destination destroyed message, we can still see queue with query dst.
calling destroy also has no effect
imqcmd -b xx.xx.xx.xx:37676 -u admin -pw admin destroy dst -t q -n testdel
Query that should remove destination looks like this (for both reap and destroy):
DELETE FROM MQDST41Cmqm WHERE ID = 'Q:testdel' AND NOT EXISTS (SELECT * FROM MQMSG41Cmqm WHERE DESTINATION_ID = 'Q:testdel') AND NOT EXISTS (SELECT * FROM MQBKR41Cmqm WHERE ID <> 'b1' AND STATE = 1)
From what i understand, the last NOT EXISTS (SELECT * FROM MQBKR41Cmqm WHERE ID <> 'b1' AND STATE = 1) would basicly translate into "if there isn't any other active broker in cluster" , so that means we cannot remove any autocreated destination if there are other active nodes in the cluster.
