Creating a Fallback Configuration

Use

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.
Select the consumer proxy and choose Apply Selection.

The configuration is displayed. If a service group is assigned to a provider application, the provider application and the consumer proxy are displayed.
Go to the Configurations tab.
Select the icon.

Note

You 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.
Select the method for creating the logical port.

The procedure for creating and configuring a logical port is the same as normal.

Choose Save .

The consumer proxy is now generated and configured.

Note

If 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.
Activate the configuration requests for the service group.
1. Go to the Service Administration tab
2. Choose Pending Tasks .
  
  An overview of configuration requests is displayed.
3. Choose Rebuild List .
4. Choose Process List .
  
  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 the SOA Manager, go to the Service Administration tab.
Select Web Service Administration .
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 the Delete icon.
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.
