Password File

Oracle Database XE uses a password file to authenticate a user who is logging in remotely as user SYS. The SYS user can then perform administrative functions from a remote workstation. The password file contains the SYS password (encrypted). Whenever you change the password for SYS, the password file is automatically updated.

The password file is automatically created when you install Oracle Database XE. Unlike the other physical structures of the database, the password file is not backed up to the flash recovery area.

Note:

Under typical circumstances, you should never log in to Oracle Database XE as user SYS.
