Jonathan,
 At the seminars I have attended it was pointed out that the :true RAC"
is COMPAQ only. The seminar was hosted by Oracle/Compaq. Compaq RAC
allows multiple CPU's to mount and use/share the same datafiles in a
true RAC configuration. The drives including the os drive are on a SAN
and shared by the CPU's so knowledge is shared. It was pointed out the
new Linux RAC can only share a RAW device and not a datafile. I don't
know if this is true as I have not tried it yet. The speaker at the
seminar said that with other OS's a RAC is like a High Availability (HA)
option, one CPU is doing nothing until the first one fails or you only
run different applications and datafiles on one CPU and other
applications and datafiles on the second CPU. if one fails you have to
mount the datafiles and switch applications to the active CPU.
  To use a true RAC you have to use Compaq and I think the market share
of the OS's are not True64, so there are probably not a lot of users of
RAC.

I was talking w/someone today, and we realized that neither
of us knows of anyone actually using RAC in production. So
now I'm curious. Is anyone?
