Hello Friends,
I have a production server running on windows2000 server with 9i
Its running for the last one year smoothly..

Suddenlty I found that I am unable to login as sys.
1)
SQL> connect sys/<password> as sysdba
ERROR:
ORA-01017: invalid username/password; logon denied
2)
SQL> connect sys/ as sysdba
Enter password:
ERROR:
ORA-01031: insufficient privileges

No body has changed password. I tried setting the password by logging in as system from EM, Its been able to set but still cannot login.

Currently unable to login as sysdba. I am suppose to login as sysdba using any user from the server because of Login user authentication. It is the same user<Administrator> who is in ORA_DBA group. How can I solve it .

any ideas will be helpfull ....Please help me.
Regards,

Thanks for the helps,

1)
SQL> connect / as sysdba
ERROR:
ORA-01031: insufficient privileges

2)
#sqlnet.authentication_services = ????

>>>SQLNET.AUTHENTICATION_SERVICES= (NTS)
Inside the file E:\oracle\ora92\network\admin\sqlnet.ora

3) What is the risk of creating password file ?
I have password file exists in E:\oracle\ora92\database\PWDora816.ora

I need to create new one or over write it ?
Its bit confusing ........

Thanks & Regards

You should recreate your password.
No risk...
Must use "FORCE=Y" Keyword with create password file statements.


ORAPWD FILE=$ORACLE_HOME/DBS/PWD<SID>.ORA PASSWORD=PWD ENTRIES=XXX FORCE=Y
