sangeetha, 1. When a tablespace is deleted, the users do not get dropped. Users would still be present. However, the tables created on the tablespace would be dropped. Users and their details are maintained in Oracle dictionary. If you have DBA permissions on your database, check the view, dba_users. You would see all the users.
2. A rollback segment stores any data that is changed in the database. But there are many ramifications for a rollback segment. Read Oracle concepts manual for a complete understanding of rollback segments. 3. There are many differences between Oracle 8i and Oracle 9i. Listing them here would be very lengthy. You could create a user account in http://otn.oracle.com/ . It is free. There go to this link -- http://otn.oracle.com/products/oracle9i/content.html . In this you would see a title - Oracle 9i features.
