Enter user-name: conn / as sysdba
Enter password:
ERROR:
ORA-01017: invalid username/password; logon denied
The special string / as sysdba tells Oracle to use OS Authentication instead of a username/password. Your OS (looks like Windows) is not authorizing you to connect to Oracle as sysdba.
Make sure your Windows user is a member of the ORA_DBA local group on that computer.

I tried to connect to database using sqlplus using below command :
sqlplus / as sysdba
I have used the same password that I had set while creating database and setting password for sys and sysdba. But it shows below error :
ORA-01017: invalid username/password; logon denied
How to connect to the database?
I have installed Oracle DB in local PC with Windows 10 as Operating System and administrator privileges.
Log on to your Windows server as a member of the Administrators group or a member of the ORA_DBA group.
Try the below steps
sqlplus /nolog
connect / as sysdba
Once connected, you can change the SYS password to something you know:
ALTER USER sys IDENTIFIED BY new_password;
I want to connect to oracle as sys user with sysdba privil..
How can I do it using easy connection
I am doing so:
sqlplus sys/password#server:1521/orcl as sysdba
and getting error:
ORA-01017: invalid username/password; logon denied
Is it correct syntax?
Thanks.
You are trying to connect remotely as sysdba (port 1521 in your case). Connecting as sysdba from a remote location (over tcp or tcps) requires some extra steps:
Set the database parameter REMOTE_LOGIN_PASSWORDFILE = { shared | exclusive | none }.It should be set tp shared/exclusive.
Check your password file under $ORACLE_HOME/dbs/, which is being used for authentication when users login to the database as a sysdba. If the password file does not exist then create a new one (using orapwd) and set the password.
in sqlnet.ora file:
when i have SQLNET.AUTHENTICATION_SERVICES= (NTS)
i can't connect by PL/SQL developer arises "ORA-12638 Credential retrieval failed"
,but can connect by command line
when i have SQLNET.AUTHENTICATION_SERVICES= (NONE)
i can't connect
>sqlplus / as sysdba
arises "ORA-01031: insufficient privileges"
,but can connect by PL/SQL developer and command line when i supply username and password
I was facing the exact same issue.
When I made the change to
SQLNET.AUTHENTICATION_SERVICES= (NONE) to resolve the ORA-12638 Credential retrieval failed.
I was then unable to connect with the sysdba privilege.
ORA-01031: insufficient privileges when sqlplus / as sysdba
The Solution:
I was able to find out, I could still connect as sysdba with the following command:
From within sqlplus:
connect sys as sysdba
From command line:
sqlplus sys as sysdba
In both cases, you will be prompted for your password. The password will be the same as your password that you setup for the SYSTEM user during the windows Oracle install.
Now you are connected with the sysdba rights you were trying to get with sqlplus / as sysdba.
The server administrator may not have setup NTS authentication on the database. You can't simply ask for your credentials to be authenticated by NTS in your client SQLNET.ORA file without agreement on the server side.
