Re: Ora-8103 error

Is having Guardium configured for that database will help in getting the details of the exact DDL query/source? Or it depends on what logging has happened through the guardium there ? I see, the DBA's there are not aware of how to fetch the guardium log/report so any information on that part will be helpful.
