Destination defaults [Settings]

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

To view this page in the console, click the following path:

Service integration -> Buses -> bus_name -> [Topology] Foreign bus connections -> foreign_bus_name -> [Additional Properties] Destination defaults.

These properties apply when there is no explicit foreign destination or alias destination defined on the local bus to provide destination defaults.

Configuration tab

The Configuration tab shows configuration properties for this object. These property values are preserved even if the runtime environment is stopped then restarted.

General Properties

Default priority

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

Dynamic updates to this property are effective immediately.

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.

Dynamic updates to this property are effective immediately.

Data type	drop-down list
Range	Best effort nonpersistent Messages are discarded when a messaging engine stops or fails. Messages might also be discarded if a connection used to send them becomes unavailable or as a result of constrained system resources. Express nonpersistent Messages are discarded when a messaging engine stops or fails. Messages might 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 might 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.

Dynamic updates to this property are effective immediately.

Send allowed

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

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.

Include an RFH2 message header when sending messages to IBM MQ.

If selected, messages sent to IBM MQ includes an RFH2 header. The RFH2 header stores additional information to that which is stored in theIBM MQ message header.

This property applies when a foreign bus connection represents an IBM MQ queue manager or queue-sharing group. When service integration converts a message from the service integration format to IBM MQ format, by default it includes an MQRHF2 header in the IBM MQ message. This header contains message attributes, such as JMS message attributes, that are not IBM MQ message attributes and therefore do not appear in the IBM MQ message descriptor (MQMD). Some IBM MQ applications cannot process messages that include an MQRFH2 header. If messages sent to this destination will be processed by IBM MQ applications that cannot tolerate an MQRFH2, clear this option.

Dynamic updates to this property are effective immediately.
