Creating a Fallback Configuration 
If a failure occurs in a service group, the service connections will not be correctly configured and may fail. When a failure is identified, the configuration profile can be switched to a fallback configuration that you define.
Prerequisites
The service group must be assigned to a provider application.
A service group can be used to generate and configure a fallback logical port only if it is assigned to a provider application.
Procedure
Creating a Fallback Logical Port
You configure a fallback logical port in the same way as for Web service configuration. The only difference is that the logical port is set as the fallback logical port for a service group. Normally, profile configurations cannot be changed manually. However, when you create a fallback logical port, the profile can be overridden.
From the main screen of SOA Manager, go to the Service Administration tab.
Select Web Service Configuration.
Specify a service group.
To create a fallback logical port, the service group must first be assigned to a provider application. If a service group is assigned to a provider application, the provider application and the consumer proxy are displayed.
Select the consumer proxy and choose Apply Selection.
The configuration is displayed.
Go to the Configurations tab.
Create and configure a fallback logical port.
NoteYou can only specify one fallback logical port for a fixed combination of service group, consumer proxy and provider application. At runtime, only one service configuration can be used for fallback.
End of the note.A fallback logical port is created in the same way as a manual logical port.
More information: Configuring a Consumer Proxy
Choose Save.
The consumer proxy is now generated and configured.
NoteIf a fallback logical port exists for a service group, it will be used instead of the logical port specified in the configuration profile.
You can change the configuration for the fallback logical port in the same way as any other manual configuration. The assignment used in the service group remains unchanged.
If you no longer need to use the fallback logical port, you need to delete it.
End of the note.Activate the configuration requests for the service group.
Go to the Service Administration tab
Choose SOA Configuration Request Queue Management.
An overview of configuration requests is displayed.
Choose Start request queue processing.
The requests are processed.
If any requests were not processed because there was no logical port for the service group, they should now be processed without any errors, using the new fallback logical port.
Deleting a Fallback Logical Port
If a fallback logical port exists, business scenario configuration cannot overwrite it. For this reason, you need to delete a fallback logical port manually.
From the main screen of SOA Manager, go to the Service Administration tab.
Select Web Service Configuration.
Specify a service group.
Select the consumer proxy and choose Apply Selection.
The configuration is displayed.
Go to the Configurations tab.
Select the fallback logical port and choose Delete.
Confirm.
The consumer proxy is now deleted.
When a fallback logical port is deleted, a new logical port will be automatically generated for the service group.
