To destroy a physical destination, use the imqcmd destroy dst subcommand:
imqcmd destroy dest -t destType -n destName
This purges all messages at the specified destination and removes it from the broker; the operation is not reversible.
For example, the following command destroys the queue destination named curlyQueue:
imqcmd destroy dest -t q -n curlyQueue -u admin
You cannot destroy the dead message queue.
