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 osb route node error handler add at least one stage to the page to specify how the osb error handling best practices error handler will work. See the following topics: Section 24.2, "Adding Proxy Service Error Handlers" Section 24.3, "Adding Pipeline osb service callout error handling Error Handlers" Section 24.4, "Adding Stage Error Handlers" Section 24.5, "Adding Route Node Error Handlers" Section 24.6, "Editing Error Handlers" "Handling Errors in Message Flows" in the Oracle Fusion Middleware Administrator's

Guide for Oracle Service Bus. 24.2 Adding Proxy Service 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." To add a proxy service Error Handler Click the Proxy Service icon, then click Add Service Error Handler. The Edit Error Handler page error handling in osb 12c 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 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 E

service from Oracle Service Bus. But we shut down the SOA service to generate the error so when Oracle Service Bus try to call SOA service it will get error out and we will handle that https://docs.oracle.com/cd/E23943_01/admin.1111/e15867/proxy_errors.htm fault in Oracle Service Bus. In the Oracle Service Bus error handling once we receive the fault message, we will send that fault message to JMS queue. To send message to JMS queue, we will use re-use the business service that we created in previous post. First Create an OSB project. Create three folders under project. Load SOA service WSDL & XSD file to resource folder of newly created OSB project. Create http://www.soawork.com/2014/04/error-handling-in-osb.html a Business service which will call SOA service. To create it click on business folder and choose "Business Service" from resource type drop- down. Name your Business Service and browse WSDL file of SOA web service. Choose WSDL binding and click on submit. Set the EndpointURI for SOA service. Accept defaults and save your business service. Now we will create proxy service which invokes newly created business service. To create proxy services click on proxy folder and choose "Proxy Service" from resource type drop-down. Name your proxy service and browse newly created business service. Accept default and save your proxy service. Now we will add error handling to Proxy service to handle fault generated when we call SOA service. To add error handling, go to message flow of proxy service. Click on route node and click on "Add Route Error Handler". Once you add route error handler, right-click to add the stage. Name the stage activity. Click on Edit Stage to add required activities inside error handler. Inside stage activity click on "Add an Action" and add "Publish" activity which will call JMS queue business service which send the message to JMS queue. Now we need to pass fault message to business service that we have configured inside publish activity. For that
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 some guidance but please try different scenarios and if there http://jaredsoablogaz.blogspot.com/2013/01/osb-error-handler-tutorial.html is something you are curious about add it to one of the proxy services and see what OSB does. Before we start with the hands-on exercises below is a quick overview of the key points in OSB Error Handling. OSB http://www.slideshare.net/Joelith/osb-exception-handling-logging-ofm-canberra-september Error Handling Overview Error handling can be configured at 4 different areas in and OSB Proxy Service. Proxy Service Route Node Pipeline Stage Node If an error is not handled in any of these areas then it will be caught error handling 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 error handlers are nested. Stage Node -> Pipeline -> Proxy Service -> System Error Handler Route Node -> Proxy Service -> System Error Handler Choosing an error handler action handling in osb 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 exercises are simple and are meant to demonstrate how error handlers behave in OSB. Specifically we are going to focus on how error handlers are nested and the behavior of OSB when there are no error handlers. To complete these exercises please import the Error_Handler_Demo project. You can download the project at the following link. https://docs.google.com/file/d/0B5g0v_BbuvHUV05NaVFOUWxFamM/edit The Error_Handler_Demo pro
