Destination defaults [Settings]

Properties to be applied when applications use destinations on this foreign bus when there is no explicit foreign destination definition.

Configuration tab

Configuration properties for this object. These property values are preserved even if the runtime environment is stopped then restarted. See the information center task descriptions for information about how to apply configuration changes to the runtime environment.

General properties

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 Integer
Range 0 through 9

Default reliability

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

This reliability setting is used if a message has not set a reliability or if the Enable producers to override default reliability is set to False.
  • If an application is producing messages to a destination and that application does NOT specify a reliability for the message, then the Default reliability setting is used.
  • If an application is producing messages to a destination and that application specifies a reliability, then the application reliability is ONLY applicable if the Enable producers to override default reliability property is set to True. Otherwise, the Default reliability setting is used.
Required No
Data type drop-down list
Default Assured persistent
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.

Producers cannot send messages to this destination with a reliability higher than the value specified for this property.

This attribute is not used for a temporary destination.

If the message exceeds the maximum reliability and the producer is local to the messaging engine, an exception is thrown.

If the message exceeds the maximum reliability and the producer is not local to the messaging engine, the message is sent to the exception destination that is defined for the target destination.

Required No
Data type drop-down list
Default Assured persistent
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.

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.

Send allowed

Clear this option (setting it to false) to stop producers from being able to send messages to destinations on this foreign bus.

Required No
Data type Check box
Default Selected

Enable producers to override default reliability

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

  • If an application is producing messages to a destination and that application does NOT specify a reliability for the message, then the Default reliability setting is used.
  • If an application is producing messages to a destination and that application specifies a reliability, then the application reliability is ONLY applicable if the Enable producers to override default reliability property is set to True. Otherwise, the Default reliability setting is used.
Required No
Data type Check box
Default Cleared
Range
Cleared
The option is set to False. Producers cannot override the default reliability that is set on the destination
Selected
The option is set to True. Producers can override the default reliability that is set on the destination
