I have never used hash partitions. are there performance problems with hash partitions and full table scans? It actually took longer do do a 'count(*)' on a table with 16 hash partitions than it did to create a global index on the same table. noone else is online?
also what does the following mean in my explain plan:

   1 0 PARTITION HASH (ALL)
next line is table access (full).
