I am completely new to oracle and SQL*Plus so I need a lot of help. I got the same TNS issue. I wonder if I still need to download or enable a listener on my win xp ?
Anyway, I downloaded and extracted both Basic and SQL*Plus instant client on c:\instantclient Next, I double clicked the sqlplus.exe, prompts me to enter the username and password. - I'm stuck here because I have no clue where to get those?
I tried reading the readme file for hours but I still don't understand a lot such as ORACLE_HOME (where it came from) and didn't find how to get the user and pass
