How do we force the generation of a trace file whenever an error (invalid rowid ora-01410) happens in the database. Right now only some of the ORA-01410 show up in alert log, but not all. Is there a 'alter system set event <nnn>' that can be done to achieve this? Thanks, Deepak __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
