segments created by the user if no tablespace is
specified at creation time. The value for DEFAULT

specified. Always specify a DEFAULT TABLESPACE for the
user and assign the user a quota on this tablespace if
you expect him or her to create segments.

TEMPORARY TABLESPACE

PASSWORD EXPIRE This parameter enables you to automatically expire the user’s password at creation time, forcing him or her to change the password the first time a successful connection to the instance is established. The default behavior is not to expire the user’s password, though use of this parameter is recommended.

QUOTA Lets you configure a quota for the user on tablespaces in the database. The quota is specified in bytes, kilobytes (K), or megabytes (M). You should specify a quota on the user’s DEFAULT TABLESPACE if you expect the user to create segments. You should not specify an UNLIMITED quota on a tablespace for a regular user.
