can configure error handling at the message flow, pipeline, route node, and stage level. Configure error handlers on the Edit Error Handler page. You must always add at least one stage to the page to specify how error handling in osb 11g the error handler will work. See the following topics: Section 24.2, "Adding Proxy Service Error

flow in the Edit Message Flow page, as explained in Section 21.1, "Viewing and Editing Message Flows." To add a proxy service Error Handler Click the Proxy Service icon, then click Add Service Error Handler. The Edit Error Handler page is displayed. Click the Error Handler icon, then click Add Stage. Click the Stage icon, then click Edit Stage. The Edit Stage Configuration page is displayed. Click Add an Action, then select the action you osb error handling framework want to add. An error handler is a pipeline and is therefore configured like any other pipeline. For example, you can use the Publish action to send error notifications to other services, use the Assign action to modify the context variables, and so on. See Section 22.1, "Adding and Editing Actions in Message Flows." There is no restriction on what actions may be chained together. Three commonly-used error actions are Raise Error, Reply, and Resume. Add other actions and make other edits on the Edit Stage Configuration page, as desired. On the Edit Stage Configuration page, click Save to commit the updates in the current session. On the Edit Error Handler page, click Save to commit the updates in the current session. After you finish On the Edit Message Flow page, continue to construct the message flow, as described in Section 21.1, "Viewing and Editing Message Flows." 24.3 Adding Pipeline Error Handlers Before you begin These instructions assume you are already editing a message flow in the Edit Message Flow page, as explained in Section 21.1, "Viewing and Editing Message Flows." The instructions also assume you have created a pipeline pair node, as explained in Section 21.4, "Adding Pipeline Pair Nodes to Message Flows." To add a Pipeline Error Handler Navigate to the pipeline pair node containing the pipeline to which
in OSB. I have also included a sample project which makes it very easy to try different scenarios that can help broaden your understanding of OSB Error Handling. These examples are meant to give osb service callout error handling some guidance but please try different scenarios and if there is something you are osb skip action curious about add it to one of the proxy services and see what OSB does. Before we start with the hands-on exercises message flow actions in osb below is a quick overview of the key points in OSB Error Handling. OSB Error Handling Overview Error handling can be configured at 4 different areas in and OSB Proxy Service. Proxy Service Route Node https://docs.oracle.com/cd/E23943_01/admin.1111/e15867/proxy_errors.htm Pipeline Stage Node If an error is not handled in any of these areas then it will be caught in the System error handler. An error will be handled by the inner-most encompassing error handler. In other words, if there is no error handler configured at the level the error occurred then the error will be processed by the next level error handler. Below is an outline of how the http://jaredsoablogaz.blogspot.com/2013/01/osb-error-handler-tutorial.html error handlers are nested. Stage Node -> Pipeline -> Proxy Service -> System Error Handler Route Node -> Proxy Service -> System Error Handler Choosing an error handler action An Error Handler is not considered completely configured until it has a Resume or Reply Action configured. If an error handler is missing one of these actions then the other steps in the error handler will be completed but the error will be bubbled up to the next level error handler. Reply - Will immediately reply back to the calling process with an error response and all further message processing stops. Resume - Message flow process will continue as if no error occurred. The processing will continure after the node or stage that the error handler is configure in. Configuring Error Handlers Error handlers are just another pipeline and can be configured like any other pipeline. You may use an assign action, publish action…. Etc. In the error handler a new context variable is available ($fault). The $fault context variable contains information about any error that occurs during message flow processing and is populated before the error handler is invoked. For more information on the contents of the $fault variable see OSB Context Variables Error Handler Exercises The following exer
