Understanding UNLOAD command keywords
The UNLOAD command has the following keywords. These keywords are used to indicate the modes in which the queues are to be opened. For more information about using these keywords, see the BMC MQ Message Management Command Line Interface Reference Manual.
BROWSE opens each FROM queue for browse only.
When a queue is opened in browse mode, messages cannot be removed from the queue. Simultaneously, other applications can use the queue in any mode.
SHARED opens each FROM queue for input in share mode.
When a queue is opened in share mode, messages can be removed from the queue. Other applications can access the queue in share mode at the same time and may also remove messages.
EXCLUSIVE opens each FROM queue for input exclusively.
When a queue is opened in exclusive mode, messages can be removed from the queue, but other applications cannot remove messages while the queue is open.
