Audit session and SYS.AUD$
I have a requirement to report all users who have not logged in to the database (we have straight database security) in 45 days to our security team.
I turned on audit session and I issued a query to look at AUD$ (userid and timestamp#) against DBA_USERS to provide this report. However, I've noticed that my TIMESTAMP# always contains NULL no matter what.
Any explanation for this?
