privileges

What are the proper privileges for the SIEBEL user in a SIEBEL database on an Oracle server?
I have a SIEBEL db with a SIEBEL user that was granted DBA role.  We want to revoke DBA and grant the proper privileges. 

We have these roles:
GRANTED_ROLE         ADM DEF                                                                                                                                   
-------------------- --- ---                                                                                                                                   
RESOURCE             NO  YES                                                                                                                                   
CONNECT              NO  YES                                                                                                                                   
SSE_ROLE             NO  YES    

And these system privileges.

System Privileges assigned to a user through roles
