Data type Text

Default reliability

The reliability assigned to a message produced to this destination when an explicit reliability has not been set by the producer.

Required No
Data type drop-down list
Range
Best effort nonpersistent
Messages are discarded when a messaging engine stops or fails. Messages may also be discarded if a connection used to send them becomes unavailable and as a result of constrained system resources.

For non-transactional JMS message-driven beans and MessageListeners that use a JMS destination configured on the default messaging provider, best-effort nonpersistent messages are not recoverable. In this case, if a message is unlocked because the message-driven bean or MessageListener threw an exception, then the message is not redelivered or sent to the exception destination because it was deleted from the message store when it was passed to the listener. If you require higher message reliability for non-transactional JMS message-driven beans and MessageListeners, configure a different option for the Maximum reliability property of the bus destination.

Express nonpersistent
Messages are discarded when a messaging engine stops or fails. Messages may also be discarded if a connection used to send them becomes unavailable.

Reliable nonpersistent
Messages are discarded when a messaging engine stops or fails.

Reliable persistent
Messages may be discarded when a messaging engine fails.

Assured persistent
Messages are not discarded.

Maximum reliability

The maximum reliability of messages accepted by this destination.

Required No

Enable producers to override default reliability

Select this option to enable producers to override the default reliability that is set on the destination.

Required No
Data type Check box

Default priority

The default priority assigned to messages sent to this destination when a priority has not been set by the producer.

Required No
Data type Custom
Range 0 (lowest) through 9 (high)

Maximum failed deliveries

The maximum number of failed attempts to process a message before the message is forwarded to the exception destination for the destination.

Required No
Data type Text

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.

Required No
Data type Text and Check box
Default System
Range
System
Default system exception destination.
None
No exception destination is configured.
Specify
Specify a named destination.

Send allowed

Clear this option (setting it to false) to stop producers from being able to send messages to this destination.

Required No
Data type Check box

Receive allowed

Clear this option (setting it to false) to prevent consumers from being able to receive messages from this destination.

Required No
Data type Check box

Select this option to allow only one consumer to attach to each message point. If this option is not selected multiple consumers will be allowed to attach and receive messages from each message point.

Required No
Data type Check box

Additional properties

Context properties
Context information passed to the mediation.

Message points

Queue points
A queue point is created on each messaging engine to which a point-to-point destination is assigned. It is used to hold messages pending delivery to receiving applications.
Mediation points
A mediation point is a location in a messaging engine at which messages are mediated. A mediation point is created when a mediation is associated with a bus destination.
