Licensing required for dbms_space.asa_recommendations?

Hi,

We were wondering if we can use the following query without voilating any licensing requirements when it comes to tuning / diagnostic pack

SELECT segment_name,
          round(allocated_space/1024/1024,1) alloc_mb,
          round( used_space/1024/1024, 1 ) used_mb,
              round( reclaimable_space/1024/1024) reclaim_mb,
              round(reclaimable_space/allocated_space*100,0) pctsave,
              recommendations
     FROM TABLE(dbms_space.asa_recommendations())

Can someone please shed some light if we need any extra licensing to use the above and if yes, what exactly do we need

thanks
