-- showdf.sql
-- get from dba_data_files and dba_temp_files rather that v$ views
-- jkstill - 10/29/2008 - changed method of getting free TEMP space
-- it was incorrect. currently still a compromise, but more correct
-- added pct_capacity
-- jkstill - 10/29/2008
-- 2 calculations had '/' on a line by itself
-- works in 9i, but not in 10g.
