Do the following to setup roles to manage user privileges:
- Create roles, as shown in Creating User Roles.
- Grant privileges to each role, as shown in Granting Privileges to a Role.
- Grant role membership to users, as shown in Granting User Membership in a Role.
Some privileges cannot be granted to a role. You must grant those privileges directly to a user. For information, see Granting Privileges Directly To Users.
