Re: a really non-technical question, help?

Please forgive a "me-too" post, but as one who has tried on several
occasions to correct this exact same mis-understanding on c.d.o.s, I
would like to confirm everything that Carel-Jan Engel wrote (partly
because he beat me to it!)
The document referenced
http://www.oracle.com/corporate/pricing/sig.pdf
is an interesting one I had never looked at before. An alternate
document with the same wording is at
http://www.oracle.com/corporate/pricing/databaselicensing.pdf
The last time this topic came up on c.d.o.s., someone from Oracle kind
of, somewhat, acknowledged that the licensing language is confusing.
Read the OP's question -- it specifically mentions VCS. I believe the
problem is that many people have not had the experience of running
Oracle under a Veritas Cluster Server (VCS) or HP-UX Service Guard type
of cluster, so when they read Oracle's terminology, it doesn't
completely register -- they see "standby" and they (incorrectly) think
"Data Guard".
In fact, under VCS or Service Guard, there really isn't such a thing as
a "primary" node and a "standby/failover" node -- any service/group can
normally run on any node, although there is often a default node to
start-up on. An administrative choice at a given site may be to always
run all services/groups on a particular node, but it is not in any way
the same thing as a "primary" and "standby" in the database sense, nor
is it inherent in the VCS or HP/UX Service Guard model.

Hi Kevin, and all other posters of this thread,
There are a lot of rumours around this, as you can see: you get many
different answers.
First of all, let's fix the confusion about cluster based and
replication/recovery based 'standby systems'. Data Guard and
active/passive standby (Poor Mens Rac) are different items.
