Used this command:

  alter system set events '1555 incident(forceora1555)';

Nothing generated by an ORA-1555, not even a mention in the alert log.

I found the following note to be an excellent reference:

Monitoring 11g Database Alert Log Errors in Enterprise Manager 10g and 11g Grid Control (Doc ID 949858.1)
