...or in ORA_DBA Windows group as you are on Windows.

By the way, why startup force?

You are able to login as a sys user with any password, because, your oracle is set to use OS authentication scheme. See your sqlnet.ora file. You will get idea..

So you don't know what you are really doing, just use a short cut.

startup force shutdown the database in abort mode and restart the database. This is very small database and i am using this for learning purpose. That is the reason, i used startup force.

What do you mean "you don't know what you are really doing"?
