Manage messages that use foreign bus connections

We can manage messages that use a foreign bus connection.

You must know whether the foreign bus connection represents a connection from a service integration bus to another service integration bus, or to a WebSphere MQ network, because this determines the points where we can manage messages. For a foreign bus connection from a service integration bus to another service integration bus, we can manage messages that are queued for link transmitters and link receivers.

For a foreign bus connection from a service integration bus to a WebSphere MQ network, we can manage messages that are queued for link transmitters, known link transmitters, and the sender channel transmitter.

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.

For a foreign bus connection to a WebSphere MQ network, there is one known link transmitter for each link transmitter, and one sender channel transmitter for the WebSphere MQ link that sends messages to a gateway queue manager on the WebSphere MQ network.

Complete this task when we want to view, delete, or move messages on a transmitter.

Select the appropriate task from the following topics.

Subtopics

• Configure exception destination processing for a link to a foreign bus
  We can configure the exception destination processing for a link from a service integration bus to another service integration bus or to a WebSphere MQ network. We can configure whether any undeliverable messages the link handles are rerouted to an exception destination, and whether to use a system default exception destination or configure a specific exception destination.
• Manage messages in a link transmission queue for a connection between two buses
  We can manage messages in a link transmission queue associated with a foreign bus connection from one service integration bus to another service integration bus.
• View messages in a link receiver queue for a connection between two buses
  We can view messages in a link receiver queue associated with a foreign bus connection from one service integration bus to another service integration bus.
• Manage messages in a link transmission queue for a connection to a WebSphere MQ network
  We can manage messages in a link transmission queue associated with a foreign bus connection from a service integration bus to a WebSphere MQ network.
• Manage messages in a known link transmission queue for connection to a WebSphere MQ network
  We can manage messages in a known link transmission queue associated with a foreign bus connection from a service integration bus to a WebSphere MQ network.
• Manage messages in a sender channel transmission queue for a connection to a WebSphere MQ network
  We can manage messages in a sender channel transmission queue associated with a foreign bus connection between a service integration bus and a WebSphere MQ network.
• Manage pending acknowledgement messages on a deleted WebSphere MQ link
  If a foreign bus link to a WebSphere MQ network is deleted from the WAS configuration before being drained of messages, a batch of messages pending acknowledgement remains stored in the WebSphere MQ link sender channel transmitter. We can use the dmgr console to resolve these messages.
