Hello,
I would appreciate anything you can share regarding your experiences with
calculating and setting your own tablespace OVERHEAD and/or TRANSFERRATE
parameters. Is it worth the bother, or do the default values
work well enough? I am finding the
TRANSFERRATE calculation in the Performance Guide to be a little less
that clear for RAID arrays, but maybe I am simply having a dense
moment. The calculation for spec_rate in the RAID discussion is what
confuses me, as it does not seem to me to include a time measurement.
Also, it would have been helpful if they had given their definition of a
small vs. large disk array.
Any thoughts/experiences you can share would be very much
appreciated!
Thanks,
Judy
