Manage messages in a link transmission queue for a connection between two buses

We can manage messages in a link transmission queue that is associated with a foreign bus connection from one service integration bus to another service integration bus.

We must know the link transmitter on which messages are to be managed.

A service integration bus link can have multiple link transmitters. For applications that use point-to-point messaging, there is one link transmitter for each messaging engine in the sending bus. For applications that use publish/subscribe messaging, there is one link transmitter for each topic space destination that is mapped to a topic space in the foreign bus.

Complete this task when to view, delete, or move messages that are queued for a link transmitter.

1. From the navigation pane of the console, click Service integration -> Buses to display a list of buses.

2. Select the bus whose link transmission queue to manage.

3. In the Configuration tab, under Topology, click Foreign bus connections to display a list of connections for this bus.

4. From the list of foreign bus connections, select the name of a foreign bus connection to display its details.

5. Under Related Items, click Service integration bus links, then select the check box for a link.

6. In the Runtime tab, click Link transmitters to display the list of link transmitters for messaging engines that are sending messages to the foreign bus.

7. Optional: To manage all messages that are queued for a link transmitter, select the link transmitter and complete your required task:

   • Click Delete all messages to delete all the available messages that are queued for a selected link transmitter.

   • Click Move all messages to move all the available messages that are queued for a selected link transmitter to the configured exception destination. If the exception destination is configured as None, or if the link transmitter is a publish/subscribe link transmitter, the messages are discarded. If it is configured as System, the messages are sent to the system default exception destination. If a specified destination is configured, the messages are sent to the exception destination specified for this link.

8. Optional: To manage selected messages that are queued for a link transmitter, click the name of the messaging engine from the list of link transmitters, and then click View messages to view the messages on an outbound stream from this link transmitter to the foreign bus.

9. Select one or more messages and complete the required task:

   • Click Delete to delete the selected messages.

   • Click Move to move the selected messages to the local exception destination. If the exception destination is configured as None, or if the link transmitter is a publish/subscribe link transmitter, the messages are discarded.

   • Click Refresh to view the current messages that are queued for a selected link transmitter.

     Only messages up to the specified maximum displayed messages are displayed.
