can query under General Oracle under the default user name first:

Username/Password Login ID description

System/manager SYSDBA or NORMAL cannot log on as Sysoper and can be used as the default system administrator

Sysman/oem_temp Sysman user name for OMS

After selecting a user name:

For example, ordinary users: Scott users (typically locked out).

After the user name input---/as sysdba link is successful, enter: Alter user Ordsys account unlock; (note that the SQL statement in Plus is added; symbol ends)
