Hi All,

I am having one Database user Account called dba.

This dba account has been "locked" several times over the last couple of days and this is the account i use normally.

Now, that it is being "locked" so often I must sign on as privilaged user "SYS" to unlock it.

Please help me/Suggest me that how can I find out who is trying to use this account with the incorrect password causing it to be locked.

Some of my friends suggested to have Before On-logon trigger which solves the solution.

I need some more suggestions for this issue.

Manoj Kumar

there is no "before logon" trigger exist.
Obviously that "after logon" trigger will not help you because it will not be fired when wrong password entered.

AUDIT can help you.
conn / as sysdba
alter system set audit_trail=db scope=spfile;
shutdown immediate



wait Cool

select *
from dba_audit_session
where returncode<>0;
