  3. You must comply with Oracle’s terms & conditions before using any of their products. They are displayed at http://www.oracle.com
  4. This is a private web site which shows nothing more than my understanding of certain Oracle functionality at the time when I used it. The Oracle RDBMS is a complicated product which is changing all the time. You must independently verify anything I say to your own satisfaction before following any suggestions I might have made.
