Sounds correct. The problem seems to be with how statspack is reporting
Rollback per transaction %. Apparently, from Allen's discovery, it
seems statspack is using 'user rollbacks' as opposed to 'transaction
rollbacks' in it's calculation. It can be slightly alarming when in the
situation we were discussing earlier when working with connection
pools. Oracle should probably change their conversion to use
'transaction rollbacks', in the meantime it makes better sense for us to
perform our own calculation.
