There is nothing stopping someone creating a CONN object to point to Production from DEV.
This query will tell you all the CONN objects in your UC4 System
select OH_Name, ocv_vname, DBMS_LOB.substr(ocv_value, 50)
from uc4.OH a, uc4.OCV b
where a.OH_Idnr = b.OCV_OH_Idnr
and a.OH_OTYPE = 'CONN'
and (ocv_vname = 'db.name' or ocv_vname = 'DbUserid')
order by 1
