Only if you listen to the befuddled message put out my Oracle marketing.
The technologies are completely independent. You can have RAC without
GRID. GRID without RAC. Or both.

Actually it is not a stupid question. From day one Oracle has botched
the grid message creating confusion. RAC is a great solution to the
problem of servers and instances as a single point of failure. Grid has
nothing to do with that at all except that it can be used as a tool to
manage and provision RAC clusters.

If Oracle would clean up the message I suspect sales would go up.
