Thanks very much to everyone who responded! I originally wrote:

no, you only have one set of binaries. You let Solaris do all the
work (which it will do quite effectively in general). There is no
difference between what you run on a single CPU and what you run
on multiple CPUs. Ingres and its libraries aren't MT-safe anyway
as far as I know, so you don't have any way to write to the Solaris
threads model at present. Solaris will still do a decent job of spreading
out the work, and you can run multiple DBMS servers on the SS1000 if
you want to.

You can use the same binaries. We have done it for 2 years. SPARC 1000s
are wonderful machines. I want one in my basement.

No. However, it's a biiiig mistake to use a sparc 1000 for anything that
needs reliability, so I've heard.
Better off to just buy a sparc 10, quad-cpu configuration.
Or two, for half the price of the sparc 1000 :-)
