Error Handling Framework In Soa
also describes how to use the fault management framework to catch oracle bpel error handling faults and perform user-specified actions defined in a fault policy file. This chapter includes the following sections:

An example of a fault handler is where the web service normally returns a credit rating number, but instead returns a negative credit message. Figure 12-1 provides an example of how a fault handler sets a credit rating variable to -1000. Figure 12-1 Fault Handling Description of "Figure 12-1 Fault Handling" The code segment in Example 12-1 defines the fault handler for this operation in the BPEL file: Example 12-1 Fault Handler Definition level.In this test cases I've one HelloWorld bpel process wsdl error handling ,just prints hello.We cave another parent process,CallHelloWorldComposite that calls Hello process and here we'll implement the fault policy. To implement the Error Handler we need fault-policies.xml and fault-bindings.xml file.You can access those files https://docs.oracle.com/cd/E23943_01/dev.1111/e10224/bp_faults.htm locally from your project folder as well as from MDS or some other places. Here in this case policies files are there in local project folder and in this case you need to just create those file and no entry in composite.xml http://shrikworld.blogspot.com/2011/03/errorhandling-in-soa-11g.html is required. But to access fault policy file from other places you need to add below properties in composite.xml,In this case I added policy at composite level. You can give full path of either directory structure or MDS path in those values. Now we need to design fault-policies.xml file to capture all kind of faults and actions need to be taken if error occurred.You can add your custom java code to perform any additional task like send email notification or enqueing data into custom error queue.Here is my fault-policies.xml file, ******************************************************************************* PaaS Cloud Event BusHub Application Container Cloud and Multi Tenant Services - Oracle embracing 3rd party technologies and open source projects https://technology.amis.nl/2012/04/09/runtime-fault-handle-with-the-fault-management-framework/ Oracle Database 12c Release 2 is out - just only on the cloud Oracle Functions - Serverless architecture on the Oracle PaaS Cloud Oracle SQL Pattern Recognition - introducing the Match Recognize operator New PL/SQL pragma (12cR2) to deprecate program units - sign of a modern programming language What can we learn from the Microservices movement?

The error situations can be both business (e.g. invalid data value) and runtime faults (service unavailable). I'm aiming to handle business fault as much as possible in the composite (catch) while handle runtime faults outside the composite. In the remaining of this blog I will describe an implementation of the Fault Management Framework to handle runtime faults.
