ORA-12154: TNS:could not resolve the connect identifier specified [10g XE]
There are many topics on this issue over the internet but None of them addresses this issue properly, so I couldn't find a solution to the problem.
I installed: *Oracle Database 10g Express Edition*
After the installation was done, I opened SQL Command Line
and I used the command "connect" to login
I enter the *username*
Then I entered the *password*
After a couple of seconds I got the following ERROR message:
*ORA-12154: TNS:could not resolve the connect identifier specified*
Screenshot of the error:
I installed this version of Oracle on both Windows XP 32 bit and Windows 7 32 bit and I get the same error message when it tries to connect.
Why doesn't Oracle work right after the installation?
Are there any further steps that need to be done in order to make this work? If so I would really appreciate any step by step help, I've been stuck trying to find a solution for days.

Is Oracle Service running at the Operating System level?
I assume that you are logged directly onto the Operating System & Database Server where Oracle is installed.
Here is my perspective of your reality.
SQL*Net is NOT required to connect to DB on local server.
ORA-12154 indicates that SQL*Net got erroneously involved.
open a Command Window
issue the following commands
post results back here
