Monitoring DB Admin

[WALI <hkhasgiwale () gmail com>]

....And the auditors report mentions that I (the internal IT Security 
Admin) should have independent monitoring of DB Admin activities, the likes 
of DROP, ALTERS etc on an inhouse developed accounting package using Oracle 
9i backened.

Not only this, the crazy auditing guys want to have preventive rather than 
detective controls in place for DB Admin.

How secure can we make an application if we start doubting the guys we 
trust...the next thing the auditors would want is preventive controls over 
me...Grrr!!

But still...is this doable!!??
