To configure heterogenous services for connecting to a SQL-SERVER 2005, we are trying to configure the Oracle 11gR2 database via EM.
We login using the SYS account and when we click on the listener link , Net Services Administration login page comes up, when we supply the same username , SYS , it throws out error :
" Validation Error
ERROR: Invalid username and/or password"
We are sure of the username and the password , if it was invalid it would be impossible to login as SYS.
The listener runs outside the database, and if I recall correctly when NSA prompts you it asks for the host login. You need to give the operating system credentials for a user in the DBA group.
Keep it simple..
Just make sure that you have logged in with admin account in your windows system.
If oracle is asking for OS credentials, provide your OS credentials(your windows admin username/password).
give username as "admin"
and password as"your-password".
worked for me!!

I cannot login into oracle database.
After installing Database 12.2.0 (named as TX) in command line I am typing:
sqlplus system/manager#tx
And it gives me an invalid user error.
I cannot login as a dba or sys and nothing else.
My service is running, after "tnsping tx" it looks ok.
After lsnrctl status it shows me that my instance TX is READY
Now, again, when I trying to login into tx database using system/manager it says it is wrong username/password. I didn't change anything during installation.
How can I solve this?
Are you sure that SYSTEM user's password is "manager"?
At operating system's command prompt, logged in as user who "owns" Oracle software (usually the user who installed Oracle database), run
sqlplus / as sysdba
Slash says that you're a trusted user and will let you in. Once you're connected, you can change password for any user in that database as
alter user system identified by your_new_password;
I'm trying to connect with a new user that I recently made but when I try to making a new connection this error appears
I acces to the database , scroll down to Other users , right click and click on Create user.
And I'm sure of that user exist and I'm writing the username and the password correctly.
Thank you all ! I found the mistake.
I was connecting to the Database by this way :
And when I was in that session making the New User, the user was not being created because I was doing it without SYSDBA Role. After, I was trying to login with the user I was just "created", but since I had not created it with SYSDBA Role, the system threw me the error ORA-01017.
When I realized that , I right clicked the DataBase and I checked the Properties.
And effectively I was login in without the SYSDBA Role , so I fix that , I enter the username , password and the SYSDBA Role.
After that , I connected to the Database with the Role SYSDBA user. I created the New User I was trying to making and finally it worked when I log in with it !!!
You did not provide enough info, but one of the many possibilities is that your PATH variable is broken. Or you have old connection files that even with the right user/pass they point to the wrong server,service,name. Try to download new instant clients. I will give you some examples:
instant client basic lite win64 12.1.0.2.0
instant client sqlplus win64 12.1.0.2.0
A fact about the Sql developer OS authentication is that Sql developer always tries to authorize by substituting to the user name \ without domain name.
I have installed oracle 12c and weblogic server installed.
I have configured web logic server and it is up and running.
Next step is to configure Repository Creation utility and to proceed with Forms configuration.
I opted "Prepare Scripts for system Load" because we do not have sysdba permission users.
How to configure RCU without knowing the username and password?
Note:I have the host and service details.

You can't. Username and password are obligatory.
Default username is SYS; if you use it, role must be SYSDBA. Other usernames would use NORMAL role.
If you don't know those credentials, ask your DBA; they know everything about it.
I have installed DB2 Express-C in my office machine. This machine does not allow me to create new account, so I installed DB2 using my local login account. Database installed successfully.
But when I try to connect to the database, it always says "Username/Password is invalid".
My local user account has appended with the domain name, for example: "INDDEV/Raghav"
"INDDEV" is the domain name, "Raghav" is my username.
I have tried all the possible combination, but am unable to connect
Please help me.
Thanks
The problem comes from your domain user. DB2 does not recognize by default domain users, thus your user cannot be authenticated. You can create a local user for you, OR you can use the instance user OR change the instance configuration to recognize domain users.
I installed Oracle 11gR2 on my linux server. When I want to login via sys user on my db, I enter "sys as sysdba" and when system give password , I push enter and I can login on my db with sqlplus.
But, when I try to connect on Windows with PL-SQL tool, system wants to password. If I didn't write password (I defined password, password is "sys"), I cannot login on my db.
Why?
When you connect on the same server you're being authenticated by the operating system; you can give any password you like, or it's more common to use / as sysdba.
When you connect from PL/SQL it'a a remote connection; operating system authentication isn't possible, so you're using password authentication.
When you install oracle, it creates OSDBA and OSOPER groups. Any members of this groups will have OS authentication and can logon without a password.
When you connect from another machine, it's a remote connection and you must enter the password.
More info in the documentation.
I had such a problem and even with Oracle 12c on my linux server and what i did was that each time I open a new terminal I first type
"export TWO_TASK="
(without the the quotations) followed by pressing
enter.
Next I could then go ahead to type sqlplus "/as sysdba" (now as it is with the quotations)
to connect and continue.
