Osb Raise Error Variable
to do error handling in Oracle Service Bus. To show this we have prepared a use case, error handling in osb 11g in this use case we call SOA web service from Oracle Service Bus. But we shut down the SOA service to generate the error
Error Handling In Osb 12c
so when Oracle Service Bus try to call SOA service it will get error out and we will handle that fault in Oracle Service Bus. In the Oracle Service Bus error handling once we receive the fault message, we will send http://docs.oracle.com/cd/E23943_01/admin.1111/e15867/app_error_codes.htm 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 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 http://www.soawork.com/2014/04/error-handling-in-osb.html 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 add "Replace" activity. Now whatever you want to pass to JMS queue you can choose from fault variable. We will assign fault message to body variable of business service. Add reply activity after the publish activity. Click on validate and save the flow. Activate the session. Testing Result We have shut down the SOA service so that we get fault when OSB try to cal
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 http://jaredsoablogaz.blogspot.com/2013/01/osb-error-handler-tutorial.html meant to give some guidance but please try different scenarios and if there 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 Error Handling Overview Error handling can be configured at 4 different areas in and error handling 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 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 handling in 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 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. F
