After the password file is deleted, the missing permissions are displayed in the attempt to log on to the database Create a password file: orapwd file = orapwuser01 password = Oracle entries = 3 force = y //entries is the number of users can access the force, if there is the database password file, then it will cover. 2, create create database command scripts CREATE BATABASE user01 USER SYS IDENTFIED BY ORACLE / / sys to modify the user password, the password is initial, usually to modify USER SYSTEM IDENTF
