Commercial in that you can pay for it with some expectation of support
from a vendor. It is not so much the buying it bundled that is useful,
it is also the expectation that there should be somebody to call if there
is some problem - I am not certain how well this works in practice, as
I have only paid for basic Redhat, never Piranha.

Yea, I did not try to be complete, just mentioning some of the biggest
players I am aware of (and being American, Redhat is the big player
here, with Suse being the leader in Europe).

I was not aware of this. I have only just downloaded Oracle 8.1.7 for
Linux, and I noticed it mentioned OPS. In the Solaris field which I am
much more familiar with, OPS is often run with either Sun Cluster or
more recently Veritas Cluster, with the Cluster File System and Cluster
Volume Manager from Veritas. I am not really an expert at Oracle Parallel
Server, and I thought it required other cluster software to support it,
but I just did some web-browsing and it appears that it does not.
