You are working as a Database Administrator. Despite having a password in the data dictionary as change_on_install， you always log on to the database MYNEWDB using operating system authentication. Your organization is planning to recruit two junior-level DBAs. You decide to enable remote authentication in your database so that the new DBAs can log on to the database from their workstations to carry out administrative tasks. To allow the new DBAs to perform the administrative tasks， you create a password file on the database server using the following command： ORAPWD file=d：/oracle/ora9i/orapwU01 password=admin entries=4 After creating the password file， you remove the operating system authentication and change the value of the REMOTE_LOGIN_PASSWORDFILE parameter to EXCLUSIVE.
