I suggest you see Ch 8 Database Auditing: Security Considerations in the Oracle(r) Database Security Guide 10g Release 2 (10.2) Part Number B14266-04 which covers basic reasons to audit. You can find the syntax in the SQL manual. See view dba_audit_sessions in the Oracle version# Reference manual. -- Mark D Powell -- Phone (313) 592-5148 ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Nagaraj S Sent: Friday, December 05, 2008 12:28 PM To: oracle-l@xxxxxxxxxxxxx Subject: Turn Audit to Monitor Logins Hi Gurus, I have an requirement from applicaition team to "Turn audit on for a an user in an Database, in order to monitor who logins (both failed and successful logins) to this account and when the login is made and from where, etc, as far as Oracle can capture these information.
