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.
We can use a naming convention to suggest a hierarchical structure for destinations; for example, by 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.
Information Value Required No Data type String
UUID
The universal unique identifier assigned by the system to this destination for administrative purposes.
Information Value Required No Data type String
Type
Whether this bus destination is for a queue, topic space, or some other type of destination.

Default priority
The default priority assigned to messages sent to this destination when a priority has not been set by the producer.
Information Value Required No Data type Integer Range 0 through 9
Exception destination
Use these properties to define what happens to any messages that cannot be delivered to this destination.
None
The bus destination does not use an exception destination and undeliverable messages are not rerouted to an exception destination.
Attempts to redeliver the message continue, up to the maximum failed deliveries limit set for the bus destination. Then, attempts to redeliver the message continue with a time interval between retry attempts. This interval is either the Default blocked destination retry interval of the messaging engine that is associated with this destination, or the Blocked retry timeout set for this destination. The Default blocked destination retry interval value can be used by all queue and topic destinations associated with this messaging engine. To set a time interval specifically for this destination, select Override messaging engine blocked retry timeout default, then enter a blocked retry timeout value for this destination.
Information Value Required No Data type Radio button Default Not selected
Override messaging engine blocked retry timeout default
Override the blocked queue retry interval configured on the messaging engine owning the destination.
Select this property to set the blocked retry timeout for this destination. This property is available only when None is selected for the exception destination.
Information Value Required Yes, if None is selected. Data type Boolean Default Unchecked. The Default blocked destination retry interval value of the associated messaging engine is used.
Blocked retry timeout in milliseconds
When no exception destination is configured, the time interval to apply between retry attempts, after the maximum failed deliveries limit is reached, for this destination.
This property is available only when Override messaging engine blocked retry timeout default is selected in the exception destination properties.
Information Value Required Yes, if Override messaging engine blocked retry timeout default is checked. Data type Integer
System
The bus destination uses the system default exception destination.
Undeliverable messages are routed to the system default exception destination of the messaging engine that detects the problem: _SYSTEM.Exception.Destination.messaging_engine_name.
Information Value Required No Data type Radio button Default Selected
Specify
The bus destination uses the exception destination specified in this field.
The exception destination must be a queue, on the same bus or a foreign bus, and must exist when the exception destination processing is configured.
Information Value Required No Data type Radio button Default Not selected
Maximum failed deliveries per message
The maximum number of failed attempts to process a message. After this number of failed attempts, if an exception destination is configured, the message is forwarded from the intended destination to its exception destination. If an exception destination is not configured, a time interval between retry attempts is applied.
This interval is either the Default blocked destination retry interval of the messaging engine that is associated with this destination, or the Blocked retry timeout set for this destination.
Information Value Required Yes, if an exception destination has been configured. Data type Integer Default 5 Range 0 through 2147483647
Keep count of failed deliveries per message
This option persists the failed delivery counts of the messages in the message store.
Persist the failed delivery counts of JMS messages in the message store. This option retains the count of failed deliveries even after the messaging engine is restarted.
Information Value Required No Data type Boolean Default Not selected When the option is not selected, the history of the failed delivery counts for the messages will be lost if the messaging engine is restarted.
Important: Although the property is selected, the property will not be effective until the database tables are upgraded using the sibDBUpgrade command for WebSphere Application Server v8.5 and later.
Send allowed
Clear this option (setting it to false) to stop producers from being able to send messages to this destination.
Information Value Required No Data type Boolean
Receive allowed
Clear this option (setting it to false) to prevent consumers from being able to receive messages from this destination.
Information Value Required No Data type Boolean
Receive exclusive
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.
Information Value Required No Data type Boolean
Maintain strict message order
Enable this option will maintain the strict ordering of messages for this destination.
Information Value Required No Data type Boolean
Reply destination
The name of a destination to be appended to any non-empty reverse routing path of messages sent to this destination.
This property is intended for use with mediations on reply messages.
For more information about the use of this property, see Configure a destination reverse routing path.
Information Value Required No Data type String
Reply destination bus
The bus on which the reply destination exists.
This property is intended for use with mediations on reply messages.
For more information about the use of this property, see Configure a destination reverse routing path.
Information Value Required No Data type String
Default forward routing path
The value to which a message's forward routing path will be set if the message contains no forward routing path. This identifies a sequential list of intermediary bus destinations that messages must pass through to reach a target bus destination. The format of the field is a list of line-delimited bus destinations specified as bus:name.
To forward messages to one or more bus destinations, type a list of bus destinations. Type each destination entry on a separate line, and in the form bus_name:destination_name or :destination_name
Where
- bus_name
- Is the name of the service integration bus on which the destination is configured. If we do not specify a bus name, the destination is assumed to be on the same bus as the destination for which we are setting this property.
- destination_name
- is the name of a bus destination.
Information Value Required No Data type Text area
Message points
- Queue points
- Displays a list of queue points used to hold messages pending delivery to receiving applications.
- Mediation points
- Displays a list of mediation points created when a mediation is associated with a bus destination.
Additional Properties
- Context properties
- Context information passed to the mediation.
- Mediation execution points
- Mediation execution points for the processing of messages from mediation message points that are on a WebSphere MQ server.
Related Items
- Application resources for this destination
- This pane provides an expandable tree view of all the applications and messaging resources that reference the current destination, both directly and indirectly. As many of the references as possible are resolved to links to the associated configuration panel for the referenced object.
