Oracle Database Interview Question:

What Are the System Predefined User Roles?

Submitted by: Administrator

Oracle 10g XE comes with 3 predefined roles:

* CONNECT - Enables a user to connect to the database. Grant this role to any user or application that needs database access.
* RESOURCE - Enables a user to create certain types of schema objects in his own schema. Grant this role only to developers and to other users that must create schema objects. This role grants a subset of the create object system privileges.
* DBA - Enables a user to perform most administrative functions, including creating users and granting privileges; creating and granting roles; creating and dropping schema objects in other users' schemas; and more. It grants all system privileges, but does not include the privileges to start up or shut down the database. It is by default granted to user SYSTEM.
