I have installed Oracle8i on my PC[p3]. After installation at the time of login I used "scott" as username and "tiger" as password, but it is displaying "TNS protocol error." What does it means and how do I solve this?
You can get this error message when you are using the DOS version of SQL*Plus. Before you invoke SQL*Plus, type the following:
Use your database's identifier instead of 'my_sid'.
Additionally, you can use Net Manager to create a TNS alias which points to your database. Then, when you connect with SQL*Plus, you will use this TNS alias as follows:
By explicitly stating the TNS alias, you are also telling SQL*Plus which protocol to use.
