    How To Find List Of Failed Log In Users In Auditing

    I want to find out the failed log in users from a pool of .aud files. Can any one guide me in this context? I am using oracle 10g.
    Thanks.

    -- You need to enable auditing if you already haven't:

    alter system set audit_trail=DB scope=spfile ;
    shutdown immediate
    startup ;

    audit session whenever not successful ;

    -- issue rights to dba user account
    grant select on dba_audit_session to your_user_account;

    -- from there ... query tables....


    set pagesize 120
    set linesize 150
    column os_username format a15
    column username format a15
    column userhost format a40
    column timestamp format a20
    column action format a10
    column returncode format 9999999999
    --spool c:\1\failed_login_attempts.log

    select os_username, username, userhost, to_char(timestamp,'mm/dd/yyyy hh24:mi:ss') timestamp,
    action_name action, returncode
    from dba_audit_session
    where action_name = 'LOGON' and returncode > 0
    and timestamp > '31-DEC-10'
    order by timestamp ;
