sqlplus Error: ORA-12560: TNS:protocol adapter error

Again I am fairly new to Oracle so it has been quite a learning process and typically I have been running into errors that are easy to resolve but being able to locate the answers easy has been challenging. While attempting to use sqlplus.exe from the Windows 7 command line I continued to receive a TNS protocol adapter error and it turns out it was simply from using the incorrect syntax. Below I describe the error in more detail as well as the correct syntax to use for sqlplus on Windows 7.

How To Login To Oracle On Windows 7 When All Oracle Accounts Are Locked

I recently installed Oracle on a Windows 7 computer to test some tools that are available in Backtrack. I am very new to Oracle so it has been a bit of a learning process including the fact that I had no idea you can install Oracle without having to pay any money to download it so I also plan on writing an article on how to do this. Anyhow after the initial Oracle install we were testing oscanner from Backtrack and locked all of the Oracle accounts which was a bummer because I wasn’t sure there was a way to correct the issue. Turns out it is really easy to unlock the Oracle accounts if you have access to the Oracle server so below I describe how to unlock Oracle accounts when it appears they have all been locked.
