*lol* Right you are.
I give Oracle a head start: Don't use DB2's range clustered tables in an OLTP system (any more than I would use hash clustered tables in Oracle for the same purpose..)
It is a drag race, that's for use.
To give the benchmark credit though: One can learn a lot from it as long as one keeps in mind that it's a benchmark. Cheers
Serge
