Home -> Community -> Mailing Lists -> Oracle-L -> Re: RAC
It's true that the *best* platform for 9iRAC is Tru64, as it is the base
port for that product. But 9iRAC (with reduced feature set) is currently
available across most major Oracle ports already -- it just doesn't include
many of the advanced clustering features that come as part of Tru64 and the
Oracle9i RAC implementation on that port.
Perhaps others on this list can verify, correct, or augment, but this is my basic understanding...
So Compaq does have a right to claim that it is the only "true" 9iRAC solution today. Since many of the upcoming 9iRAC product features are native to Tru64, in cases of feature overlap it will be interesting to see if future versions of 9iRAC utilize the existing Tru64 features (as the current version of 9.0.1 does) or the newly-included Oracle features?
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?
