It's been more than two years since I originally configured Grid Control -- and perhaps standalone Database Monitoring differs -- but GC rightly squawks at me with every ORA- error via the "Generic Alert Log Error" metric setting.

I believe I removed the warning threshold making every ORA-* error critical in GC's eyes. Perhaps this could help you as well. You'll need to be the judge of how that setting will affect your environment.

I also have a home-grown Perl script that monitors every log and trace for me that picks it up as well, just in case.
