Hi
I have a database account that always locked. How do I trace what user or desktop using this account?

I didn't turn on the audit trail as it is a small database.
I have set a 'failed logon attempts' in my database. my database is in version 9.2.0.8

Thanks.

Excuse me but if the account is really, really locked,
then please explain how anyone can be using it.

To me, you are asking the equivalent of the following:
I have a iron post encased in HUGE block of solid concrete buried into the Earth.
How can I show it doing 100 K/Hour on my radar gun?

Why did you not say so in the 1st place?
Look in listener.log for from where the connections originate.
It will contain at least the IP# of the culprit.

Hi

I have a similar problem , my environment is a 3-tier architecture , i.e. all users connect to DB via Application server , i activate audit_trail to 'DB' , but when i select the userhost from dba_audit_session it gave me the application server name , is there any way to return the real hostname of client side , by the way i configured the WebUtil if it useful to solve this problem.

best regards;

Hi all ;

We have 3-tier architecture in our site (the end users connect to Database 10g via Application Server 10g) ,I need a solution for auditing the failed login attempts, i.e. retrieving information about the end users (hostname , os user), i activate audit_trail='DB' ,

When we make

SQL> select username, userhost, os_username from dba_audit_session;

USERNAME USERHOST OS_USERNAME
------- -------- -----------
scott host01 user01
scott app01 oracle

So as you see , I have the oracle owner (oracle) and the application server name (app01) when I logged from oracle application server,

where as it is clear to see all information when you log direct to Database such as SQL*PLUS(userhost = host01, OS_USER=user01).

by the way we configure WebUtil on the application server .

How we can take the advantage of webutil to audit the failed login through oracle application server either by using audit trail or Logon triggers.

Best regards;

I don't know WebUtil but the database only knows who connects to it that is, in your case, the application server.
This one have to itself logs the connection.

P.S. don't multipost the same question. I merge the 2 topics.

hi

thnk u for ur response , as i know WebUtil can give you the IP address of the Clients via application server see
http://www.oracle.com/technology/products/forms/htdocs/webutil/webutil.htm

but i need to audit the end users action , the whole story started when one of the end users know the the username of his partner without password , and we apply the profile policy by setting the failed_login_attempts to 3 , so when he tried 3 times it locked the user until his partner call DBA to unlock it again , this is an illegal action , so my manager wants to know who did it .

Please help

thanx again

my managed to find the root cause. basically the problem is on one of the services. for my case is a grid agent services which is still running and is hard-coding old password in the database server.

your problem should be the same.

Hi all

No I think there is a parameter that can be changed to let the application server (enterprise manager) displays the whole information about the end users.

As you know if you set the parameter em_mode=1 in formsweb.cfg , then you can display the IP address of all active sessions , but I don't find any thing related to failed login ...

thanx
