Hi, I haven't gauged the performance overhead of using FGA, but it's works like a charm. I'll let others to comment on performance overhead of using it. As far as auditing DDL's, you need to get to 10g (i assume your using 9i) which supports auditing select as well DDL's. -Stalin _____ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Patamalla, Chaya Sent: Tuesday, June 15, 2004 11:58 AM To: oracle-l@xxxxxxxxxxxxx Subject: Fine Grain Auditing. Has any one worked with Oracle's Fine Grain Auditing. What is the performance overhead. Also, has anyone asked for auditing DDL? We are getting requirements about auditing DDL functionality.
