Not any user but only users that are the OS (sys)dba group.
So don't put any user in this group.
If you want to completly forbid "/ as sysdba" connection then use the following in your server sqlnet.ora file:
SQLNET.AUTHENTICATION_SERVICES = (none)
Regards
Michel

With the password!!!!!!!
If you don't know what it is then you're going to have to go back to using sqlplus "/as sysdba".
And will you please stop using IM speak. Use proper words.

I have set the parameter sqlnet.authentication_services=(NONE) in sqlnet.ora file.After that when I m firing a command sqlplus "/as sqlplus".It shows error like insufficient priviledge.Now i want to know how can I start an instance?
Is it possible to remove only sys user from ora_dba group?
If yes then how?

I have alredy tried this.Its working.It is useful if only one database is running on your computer.If two database is running on a same computer then another will not work because we have set the parameter sqlnet.authentucation_services=(NONE) in sqlnet.ora file.
