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 https://svgonugu.com/2014/10/15/service-bus-12c-error-handling/ 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. https://docs.oracle.com/cd/E23943_01/admin.1111/e15867/proxy_errors.htm 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 you want to add an error h

OSB error handling, how errors should be handled. The error handling will differ based on the communication pattern, whether the call is synchronous or asynchronous. If the services are modeled to be synchronous it will be always useful to return a consistent error structure with a minimum of the error occurring service information, unique id w.r.t message so as to track it, unique error code, summary/details of the error. This needs to be defined properly and laid out before we start on a project. If the services are more asynchronous in nature, then it makes sense to have a common Error logging/handling/auditing framework which will receive the errors and based on any business rules can persist /notify the errors. In both approaches it is mandatory to define the Error message structure. The asynchronous can have more information whereas synchronous can be a subset of this since the caller or consumer need not be given a lot of unnecessary information related to error. The synchronous response should be more formatted to be humanly readable and no stack trace. In case of OSB there can be multiple proxies and you will need to control the response message flow and track it. Instead of having multiple reply points from error catch blocks it will be better to have multiple catch blocks which will Raise an Error with the error payload populated into the body. The Global catch block will do a reply with success to the caller Proxy with the body OSB Implementation The different stages in OSB should be segregated and defined properly. And each stage should be having Error Handler-catch block. In each catch block Catch the error globally and Reply with success An error should contain minimum of below listed information so that it helps in identifying/tracking the error.
