I am using 10g Express Edition on Windows XP.

I click on Start -> Oracle Database 10g Express Edition -> Go to Database Home Page

I enter my system username and password no problem.

Then I try to do the same thing in SQLPLUS. I enter the same system name and password and I get the following error:

ORA-12560 TNS:protocol adapter error

Why does oracle database home page understand my system name and password and not SQL Plus. Received on Sun Aug 02 2009 - 21:54:24 CDT
