As described in
Deploying Your Processes, you can run your BPEL processes on A Process Server. You can connect to a running, suspended, completed, or faulted process from within Process Developer for remote debugging.
When the process instance is opened in Process Developer, you have full access to the debug features you use during simulation, such as setting a breakpoint, stepping or running to a breakpoint, following highlights along the execution path, and inspecting process variables. You can also modify data values and retry activities.
Before you can debug a process remotely, you must complete the following:
Create and validate a BPEL process
Create a process deployment descriptor file
Create a business process archive
Deploy the business process archive to the Process Server
Keep a copy of the BPEL and WSDL files in your workspace project
Start the server
Instantiate the process by sending an appropriate message to it
Select the following topics for remote debugging details.
