To set a queue's propertiesThe properties of a queue can be dynamically set by calling MQSetQueueProperties. All open instances of the queue are immediately affected when MQSetQueueProperties is called.
Note In most cases, any application can set a queue's properties. However, if MQ_ERROR_ACCESS_DENIED is returned to the MQSetQueueProperties call, the queue's access control is blocking the application from setting its properties. For information about access rights, see Access Control.
Not all properties can be set by MQSetQueueProperties. The following table indicates the properties that can be set and that cannot.
