General properties

Identifier

The identifier by which this destination is known for administrative purposes.

Do not use an underscore character "_" as the first character, because this naming convention is reserved for system use.

You can use a naming convention to suggest a hierarchical structure for destinations; for example, using dotted notation for a destination name Library.Shelf.Book1A. Such structure can be useful for organizing queues into logical groups for ease of association, and to permit the use of wildcard notation in filters; for example, Library.Shelf.* or *.Queue.accountXYZ.

Exception destination

The destination to which a message is forwarded by the system when it cannot be delivered to this destination.

Use this property to define what happens to any messages that cannot be delivered to this destination. By default, such messages are routed to the system default exception destination of the messaging engine that discovers the problem; _SYSTEM.Exception.Destination.engine_name.

If you want to messages to be sent to another exception destination, select Specify then type its name on this property. The exception destination must be a queue, on the same bus or a foreign bus, and must exist when the destination is created.

If you do not want undeliverable messages to be routed to an exception destination, select None.
