What is the default tablespace?

What is the default tablespace for the end user, and what is the authentication method for this user?

If the DBA who created the user didn't specify one, the default tablespace is SYSTEM (not good!).

As far as authentication goes, there isn't a default. The way a user logs on/authenticates is based on the selection of the DBA when creating the user. A user will either be IDENTIFIED:

  1. BY password - The BY password clause lets you creates a local user and indicates that the user must specify password to log on.
  2. EXTERNALLY - Specify EXTERNALLY to create an external user. Such a user must be authenticated by an external service (such as an operating system or a third-party service).
  3. GLOBALLY - The GLOBALLY clause lets you create a global user. Such a user must be authenticated by the enterprise directory service.
