How Oracle forgot Password reset

Yesterday installed oracle11g R2 to the Scott user to set the password, then did not display and only to enter once, may password input error, the results of today with Scott User login really password wrong, fortunately SYS and system users are normal, went in to reset the

Sql>alter user Scott identified by password; Password is the password you want to set, preferably starting with a letter

But if SYS and the system password are forgotten, they can be modified.

Here's how:

Open Run, enter

Sqlplus/nolog

Open Oracle's console and enter

Conn/as Sysdba; You are prompted to connect

is connected

And then change the password just like the normal user.

Sql>alter user system identified by password; Password is the password you want to set, preferably starting with a letter

This can be done under Linux

Su-oracle
Sqlplus/nolog
Conn/as SYSDBA
Startup (starts if the database is not in the startup state)
ALTER user SYS identified by password
You can then log on using the SYS user password
