Manage messages in a link transmission queue for a connection to a WebSphere MQ network

Manage messages in a link transmission queue that is associated with a foreign bus connection from a service integration bus to a WebSphere MQ network.

We must know the foreign bus connection and the link transmitter for which to manage messages.

A link can have multiple link transmitters; one for each messaging engine that sends messages on the link to the foreign bus, and one 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. Start the console.

2. In the navigation pane, click Service integration -> Buses to display a list of buses.

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

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

5. Select the name of the foreign bus connection to display its details.

6. Under Related Items, click WebSphere MQ links, then select the name of the link.

7. In the Runtime tab, click Sender channel to display the sender channels that are sending messages to the foreign bus.

8. 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 the selected link transmitter.

   • Click Move all messages to move all the available messages that are queued for the 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.

9. 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.

10. Select one or more messages and complete one of the following tasks:

    • 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 the selected link transmitter.

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

Results

You have managed the messages that are queued for a specified link transmitter for a specified foreign bus connectoin.
