Errors can occur during Message Flow processing for various reasons. For example, security errors occur if a username is not correctly validated or authorized; transformation errors occur if AquaLogic
Raise Error In Osb
Service Bus is unable to successfully transform or validate a message; a routing error is raised if a routing service is unavailable, and so on. Typically, these errors originate from a specific stage, route node or from the proxy service, as this is where most of the Message Flow logic is implemented. AquaLogic Service Bus provides a mechanism to handle these errors by enabling you to define error handlers. An error handler is a pipeline that allows you to perform various actions such as logging, transformation, and publishing to handle errors appropriately. If an error occurs within a stage a sequence of steps are executed. This sequence of steps constitutes an error pipeline for that stage. Nested Error Handlers You can configure an error handler for the entire Message Flow as well as for every pipeline and stage within the Message Flow. You may also configure error handlers for route nodes but not for branch nodes. When an error occur
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 the

error handler will work. See the following topics: Section 24.2, "Adding Proxy Service Error Handlers" osb service callout error handling Section 24.3, "Adding Pipeline Error Handlers" Section 24.4, "Adding Stage Error Handlers" Section 24.5, "Adding Route Node Error Handlers" Section 24.6, "Editing Error difference between reply with success and failure in osb 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 https://docs.oracle.com/cd/E13171_01/alsb/docs21/consolehelp/proxyerrors.html 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. 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 er
