Can you please let me know how to check the privileges assigned to a role in Oracle?
When I query the dba_tab_privs it says no rows returned.
When you've checked the manuals and identified the views suggested by other posters you will find that it's still not a trivial problem since a role may be granted to another role - which means you need to do some recursion to uncover all the privileges available to a role.
Pete Finnigan - who specialises in Oracle security - published some appropriate scipts a few years ago; they are probably still relevant. Here's a starting link: http://www.petefinnigan.com/weblog/archives/00001243.htm
