Recursive SQL

Hello.

This one recursive SQL I find, is a big one in the Top 10 SQL on ouur database, taking over a billion buffer gets. In one particular hour, I find this SQL responsible for nearly 15% of Total. It executed nearly 157K times.

select c.name, u.name from con$ c, cdef$ cd, user$ u where c.co n# = cd.con# and cd.enabled = :1 and c.owner# = u.user#

The question I have is, how I can tie this to a User SQL? Your input appreciated.
Thanks,
Shiva
