Downloaded Oracle Database Express Edition 11g Release 2 for Windows x32 at the following link: http://www.oracle.com/technetwork/products/express-edition/downloads/index.html
Download went good. Download successful. I follow the Oracle Database Express Edition: Getting Started Guide.
All is good until I get to the "Creating a Database User" section to connect to SYSTEM user....
I open the Run SQL Command Line and the following is exactly what I see:
Enter user-name: system
Enter password: <type my password here>
ORA-12154: TNS:could not resolve the connect identifer specified
Furthermore, tnsnames reads (I've changed my PC name to hostname for this example, but it actually reads my PC name correctly):obfuscating your hostname is useless, silly, & counterproductive since hostname could be part of the problem
