Modifying a routing definition

You can change the properties for an existing routing definition between a local bus and a foreign bus. The routing definition defines the virtual link between two buses that enables them to exchange messages.

About this task

The routing definition is created when you create a foreign bus. To change the properties of the routing definition, use the administrative console to complete the following steps:

Procedure

  1. In the navigation pane, click Service integration > Buses. A list of buses is displayed in the content pane.
  2. In the content pane, select the local bus associated with the foreign bus.
  3. In the content pane, under Topology, click Foreign buses. A list of foreign buses is displayed.
  4. Select the foreign bus.
  5. In the content pane, under Additional properties, click the routing properties option. The title of the routing properties option will vary according to the type of routing definition; it will be one of the following:
    • Service integration bus link routing properties
    • WebSphere MQ link routing properties
    • Indirect routing properties
  6. Specify the new routing properties:
    • For a virtual service integration bus link or a virtual WebSphere® MQ link, specify properties as follows:
      Inbound user ID
      The user name used to authenticate inbound message flows from the foreign bus.
      The inbound user ID is used to authorize individual messages arriving from the foreign bus to destinations in the local bus. Where it is defined, the inbound user ID supersedes the user ID in messages arriving at the local bus from the foreign bus. If the local bus is not secure, the inbound user ID has no affect on messages. You may want to specify an inbound user ID for the local bus when:
      • The foreign bus is in a different security domain, user IDs in the foreign bus are not recognized in the local bus
      • You want to control locally access to inbound messages to the local bus.
      In the case where the local bus is secure, the foreign bus is not secure, and an inbound user ID has not been set, an inbound message from the foreign bus is only authorized to destinations that allow unauthenticated users access.
      Outbound user ID
      The user name used to authenticate outbound message flows to the foreign bus.

      The outbound user ID replaces the user ID that identifies the message source in every message sent to the foreign bus. Where it is defined, the outbound user ID replaces the user ID in messages sent by the local bus to the foreign bus. If the local bus and the foreign bus are both secure, and the foreign bus has not overridden the user ID with its own inbound user ID, the foreign bus also uses the outbound user ID to authorize the message to its destination.

    • For an indirect link, select the name of the next service integration bus in the sequence of connected buses.
  7. Click OK.
  8. Save your changes to the master configuration.
