Create Role/Grant Role IDS 9.4

Hi All, I've seen documentation how to create a role in IDS 9.4. What i want to accomplish is to use the CREATE ROLE/GRANT ROLE command. ROLE1 = Read only users for all tables per user ROLE2 = SELECT,INSERT, UPDATE, DELETE on all tables per user .................. Question: 1. where in the DB can i check the ROLE setup? Currently, what i do is execute the GRANT SELECT,iNSERT, UPDATE, DELETE on table AS OWNER. I want to use the ROLE command.
