Utilisation du package DBMS_METADATA:

set long 20000 longchunksize 20000 pagesize 0 linesize 1000 feedback off verify off trimspool on 
column ddl format a1000 

begin 
    dbms_metadata.set_transform_param (dbms_metadata.session_transform, 'SQLTERMINATOR', true); 
    dbms_metadata.set_transform_param (dbms_metadata.session_transform, 'PRETTY', true); 
end; 
/

variable v_role VARCHAR2(30); 

exec :v_role := upper('&1'); 

select dbms_metadata.get_ddl('ROLE', r.role) AS ddl 
from dba_roles r 
where r.role = :v_role 
union all 
select dbms_metadata.get_granted_ddl('ROLE_GRANT', rp.grantee) AS ddl 
from dba_role_privs rp 
where rp.grantee = :v_role 
and rownum = 1 
union all 
select dbms_metadata.get_granted_ddl('SYSTEM_GRANT', sp.grantee) AS ddl 
from dba_sys_privs sp 
where sp.grantee = :v_role 
and rownum = 1 
union all 
select dbms_metadata.get_granted_ddl('OBJECT_GRANT', tp.grantee) AS ddl 
from dba_tab_privs tp 
where tp.grantee = :v_role 
and rownum = 1
