Section 18.7.2 of the Oracle BPEL Process Manager Developer's Guide 10g (10.1.3.1.0) contains instructions for enabling debug logging for a decision service. However, unless you are familiar with BPEL debugging already, there is one step missing. The logging is at the "debug" level, but the BPEL server sets the logging level to "info" by default.
To change the logging level to "debug" so you can see the logging information from your rules:
- From the BPEL Control panel, click on the "Configuration" tab.
- From that tab, click on the "Logging" sub-tab.
- For the "Logger Name" "default.collaxa.cube.engine.bpel", select "Debug" for the "Logging Level.
- Click the Apply button at the bottom of the page.
Debugging output is now enabled and will be available in the OPMN log for the domain in which the process is deployed.
