Ashoke,
In chapter 24, go through :
"Managing Audit Trail Information"
"Setting Auditing Options"
"Enabling Audit Options"
"Enabling Statement Privilege Auditing"
You will see this text :
AUDIT SESSION;
I use this query to report failed login attempts from SYS.AUD$ :
select os_username, username, userhost, terminal, timestamp, returncode
from sys.dba_audit_session
where returncode != 0
order by timestamp
/
(DBA_AUDIT_SESSION is a view on AUD$)

Joe,
We referred the auditing option. My understanding is that you can
track the oracle users using database auditing feature once the users
are logged into the database.
But my requirement is to track the users who tried to login to the
database but could not login due to wrong password.
For example, somebody may know the connect string for an oracle
database and trying to login to the database as system user and with
various combination of password. We like to know who are these users.
Thanks,
Ashoke
