Is it possible to get the all changes that is made to schema as in what privileges was first assigned to the schema on creation, creation date, if later modified with different privilege what was that priv, when the schema was dropped, basically this would be needed for audit purpose at the end of the year where they would be asking for all the info for the whole year for select schemas.
Is is possible to fetch this data from the database? I have enabled standard DB auditing for sys operations to be TRUE. Version 12.1.0.2 and 11gR2.
