* **Operability**
- * Runtime Configuration - The queue definitions and properties such as
capacity, ACLs can be changed, at runtime, by administrators in a secure manner
to minimize disruption to users. Also, a console is provided for users and
administrators to view current allocation of resources to various queues in the
system. Administrators can *add additional queues* at runtime, but queues
cannot be *deleted* at runtime unless the queue is STOPPED and nhas no

* Drain applications - Administrators can *stop* queues at runtime to
ensure that while existing applications run to completion, no new applications
can be submitted. If a queue is in `STOPPED` state, new applications cannot be
submitted to *itself* or *any of its child queues*. Existing applications
continue to completion, thus the queue can be *drained* gracefully.
Administrators can also *start* the stopped queues.
