1. How can i see what the privileges are in a particular role ?
Is there any data dict view to see the contents of a role ?

2. I want a role 'MANAGER' to have the ability to select from,insert into and update existing rows of the employees table in the hr schema. And i also want the person given this role pass it on to others.

How can i do these ?
