If you are using Windows XP then you have to be part of the ORA_DBA group to be able to use connection string like that. If you are not then you have to use:
conn sys/sys_password@db_service_name as sysdba

sys_password - one that you defined when you create the database

Cool

Then when time comes and you are part of ORA_DBA group then you will be able to use that connection string Cool

Try creating a password file ...

orapwd file=<> password=<>
and see if you can connect to db as sysdba using that password ..

Make sure that the following line is in your SQLNET.ORA file
SQLNET.AUTHENTICATION_SERVICES= (NTS)

hi

Actually you have to change parameter in parameter file .. i hope u know what is parameter file it is initsid.ora
sid stand for system identifier
so if u have database name called star then your file name must be

initstar.ora

now in this file there is one parameter change its value to none for

REMOTE_LOGIN_PASSWORDFILE=NONE

below you can know how os authentication is doen

------------------
OS AUTHENTICATION
------------------
When we load oracle, it creates a group at os level. Name of this group is ORA_DBA in 2k servers
The member (has to be authenticated user of OS) of this group can connect to DB as DBA without password

However, for that, set parameter in init.ora
REMOTE_LOGIN_PASSWORDFILE=NONE

Now to connect to DB
SQL > CONNECT / AS SYSDBA;

SQL> ALTER USER sap IDENTIFIED EXTERNALLY;
I.E. Authentication is done by OS

note:- sap is user of Operating system who is not user of Database remember sap is member of group ora_DBA...
if you dont have sap as user of operatiing system then create user sap on your os and make him member of ora_DBA..
-----------------------------------------------------------------
still u r not able to do then try things written below
-----------------------------------------------------------------

In 9i if u are able to connect as scott/tiger

then you first connect to scott tiger
you will get

SQL>

now here on SQL prompt
SQL> connect sys as sysdba
password: change_on_install

---------------------------------------------------------------

i hope things should work now ..

regards
sunil

remote_login_passwordfile parameter might have been set to none
so change it to exclusive it works

I faced the problem .. i was able to logib as scott/tiger@orcl1 .. , remember " ORCL1" is the name that i and anyone could mistakenly give in net configuratuin assistant . my actual SID name is "ORCL" .

but i could not login as sys or system.

it coccured to me that it is sytem authentication problem though i am logged in as "Administrator' in my laptop.
i checked user accounts .. i m being notified as "administrator' .
then i rember that when installing oracle .. one option came to me " changing password" for accounts of diff users ..
i remember doing some changes in that but it was all uniform i.e. the password i m using to logon as "scott".
it baffelled me why i am able to login as "scott/password@orcl1' but not as "sys"/'system'.

then i tried the following ..
create a new admin account in windows as "sas" for the computer.
switich user ..login as "sas' with admin privilrge .
start oracle services .. i.e . "listener" and "ORCL" SID. go to admin services in windows . strt both these services .
login as system/"(password which u gave during installation")@connect string ( in my case it is ORCL1.
logged in successfully.
try to connect as sys as sysdba with the same "Password" and "connect string ' . it will give error .
again reconnect as system user.
alter user SYS modify password *****
try to connect as sys with the new password .. and connect string.
get connected ...
quit SQL .
quit windows as the new user .
login as old user i.e. "ADMIn " or what ever user u were during installation .
start the oracle services i.e. listener and SID .
login as scott/password@Orcl1
then login as sys/password@orcl1 ..
success.

Moral of the story .. " It is accidental or some discrepancy " between authentication synchronization between "Windows OS" and Oracle 'Software' .. accidentally some parametrs or orcle files/windows files get changed .
still if u have the windows admin facility without going through hell i.e. " changing password files , reading thousands of responses and trying them " , de installing and re installing oracle .. try this .. it should work most of the times .. if u have valid windows admin "privilege" when installing Oracle.

no problem exists when you log onto DB server as OS user "oracle" then utilize OS Authentication
sqlplus
/ as sysdba

Neither password nor SQL*Net is required to access the DB
