I understand that I can prevent two queues from running at the same time by writing a configuration like this:
<queue name="Q1" lockqueues="Q2"/> <queue name="Q2" lockqueues="Q1"/>
lockqueueattribute on Q1 only, i.e. I do not specify it for Q2. Will it prevent Q1 from starting while Q2 is running, or vice versa? Or neither?
