Osb Error Handling Best Practices
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 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 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, "Vi

Suppose you have a service in OSB with the following pipeline: This service will always raise an error and, as this is an WSDL based HTTP web service, this will translate into a SOAP Fault being returned to the called. The contents of the SOAP Fault will be dictated by OSB with some customization made in the Raise Error stage action as can be seen bellow: When calling this service (let's name it CalleeService), we get the following response (as expected): Now, let's try to route to the Callee Service from this new one. Let's call it Caller Service and its routing configuration should be like the one bellow: With the routing configured, let's try to call our new created Caller Service. You must be expecting to receive the same error thrown by Callee Service in respone, however, that's not what happens as can be seen bellow: OSB handles the error and returns a generic protocol error. To make OSB propagate the error rec
oriented architectures. Recently, we extended some of our existing services to new clients by integrating those services with service bus. The concepts and terminology of Oracle Service Bus can be found here. New Interface with Service Bus: With this new interface, one problem http://www.insemble.com/oracleservicebus-errorhandling.html we ran into was that, in case of an exception being thrown by a service, the end client was receiving an Internal BEA error instead of the actual exception being thrown by the service. The article explains https://groups.google.com/d/topic/oracle-service-bus/qqIMdYyZN74 why this happens and provides a solution approach on how meaningful custom messages can be presented to the end SOAP client. The fundamental reason for this is because of the way, Oracle Service Bus populates its context error handling variables such as $body and $fault when an exception is risen. Details regarding context variables can be found here, but at a high level, when an exception is thrown by the backend service, the exception is put in the $body variable and a predefined System message and error code is put in the $fault variable. The web service client gets a SOAP fault which is populated by the content in $fault and that information is osb error handling of no help for any troubleshooting.
In order to provide custom error messages to the end client, we implemented the following approach Configure a Service Error Handler for the Proxy Create two proxies one a generic proxy to the business service and another client specific proxy that calls the generic proxy Leverage the Reply with Failure construct that populates $fault with $body Details regarding the various error codes generated by the service bus are available here. The error codes that are most relevant are: Error Code Explanation BEA-380001 Service up, but an application exception BEA-38002 Service unavailable Other ones Service up, but infrastructure related issue With the above information on hand, in the Service Error Handler of the generic proxy, we used the if-then-else , XQuery functions and raise Error constructs provided by the service bus to throw the appropriate user friendly exception. $fault can be interrogated using fn:starts-with($fault/ctx:errorCode/text(),"BEA-380002") $body can be interrogated for application error using fn:starts-with($body/soap-env:Fault/detail/error/text(),"ServiceProcessor.getData(): Invalid Data Sent ") � Raise Error using a custom error code with a custom error message Thus, in a nutshell, Generic Proxy identifies if it is a System exception or Application exception and rethrows a user friendly exception. The key point is that when a custom exception is thrown from the Generic proxy, $body contains the user friendly message and $fault conGoogleВойтиСкрытые поляПоиск групп или сообщений
