ORA-12560: TNS:protocol adapter error

    Following applies for Windows:

    Probably the OracleService for the database is not running.

    Check if the service is running, if not, startup the service.
    It might be that the service is setup to only startup the service and not the instance as well.
    On Windows, use the oradim utility to control this behaviour.

    You will manually have to startup your database
    C:>sqlplus

    If the service is running, you might be connected to the server using the Terminal Service Client / Windows Remote Desktop.
    This is not supported by all versions of Oracle (before 9i).

    One possible work around is to set the LOCAL environment variable in a dos box and try to connect again.

    The difference between using LOCAL instead of ORACLE_SID is that LOCAL will try to connect through the listener, so it should run as well.
    eg:
    C:>set LOCAL=ORA920

C:>sqlplus

    If the service is started and you are not using terminal services/remote desktop (using an unsupported version of Oracle) and you are relying on the default ORACLE_SID set for the Oracle Home Directory, than you're probably using the incorrect %oracle_home%.

    Use Oracle Locator express to change the Oracle Home, startup a new command prompt and try again.

On windows, you need to make sure the OracleServiceSID is running.

I had installed Oracle 10 g on my new XP system, I didn't opted for creating the stater database while installation and the Oracle setup was sucessfull. While I start the Sqlplus and provide the login as scott/tiger , it gives me the following error : TNS:Protocol Adapter Error

If you didn't choose to create a database, you will have to create a new database.
You can use the database configuration assistant (dbca) for this

08-FEB-2008 02:34:05ORACLE_SID not setDbMotive Reply
The ORACLE_SID is probably not configured in the forms server, so connections to a database will not work.
Check the forms configuration and adapt accordingly

It is the password you had to supply at creation time.

You can try with oracle, manager, change_on_install

As you have both an Oracle database and Oracle forms, what is your current Oracle home?
Is it the one of forms? If so, change it to the one of the database.

You can use Oracle Locator Express to change the homes.

We are facing an issue while connecting to Oracle 10G Express Edition via SQL PLUS and OTL Interface.



It is giving the below error:

a??ORA-12560: TNS:protocol adapter errora??



This appears to be a common error with ORACLE. We tried all the options that we read in various DB forums.

Can you post the output of the steps performed?

When you connect as "/ as sysdba", does it say "Connected to an idle instance" ?

Forms is installed into a different Oracle home, which will become the default after installation.

When you try to connect to your database, you will see this behavior.

You have to change the default Oracle home back to the original one.
you can use our free tool "Oracle Locator Express" to change the Oracle home.

Click downloads on the left hand side, and choose the correct download.
