By default, not all exceptions caught within I/PM are logged. I/PM exception handlers do not inherit a log level from a parent logger (oracle.imaging.service). To get exceptions from the core I/PM services, you must explicitly set the logger named oracle.imaging.service.exceptions.To enable some degree of flexibility, it uses the following log levels:
ERROR 1(SEVERE): Logs SYSTEM and DATABASE ImagingExceptions
NOTIFICATION(INFO): Logs SYSTEM, DATABASE, and SECURITY ImagingExceptions
TRACE(FINE): Logs SYSTEM, DATABASE, SECURITY, and USAGE ImagingExceptions
For example, all ImagingExceptions would be logged at throw time by setting oracle.imaging.service.exceptions to TRACE:32.
