The display conn command can be used to get the ID of a connection. In this example, there is a connect with ID 0938739232847.

~]# echo "display conn (*)" | runmqsc MANAGER01

  CONN(0938739232847)
  EXTCONN(418D84A8B837E3938A983ABC9)

Then the stop conn command can be used to end the connection.

echo "stop conn (0938739232847)" | runmqsc MANAGER01
