Allow database passwords to expire, and change default passwords

Oracle Database is installed with several default database user accounts, such as SYS and SYSTEM.

After the database is installed successfully, the Database Configuration Assistant automatically locks most built-in database user accounts and marks them as expired. After the accounts expire, you should configure strong and secure passwords for them.
