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
