Re: RAC and ASM - Standard vs. Enterprise Edition install process ?

The limitations are "just paper" -- until you fail a licensing audit.

Well, even then, I guess, they are still "just paper". Lots of small rectangular pieces of paper. Green ones in the United States, other colours in nations sufficiently civilized for their governments to be able to afford more than two shades of ink.

Warning on SE with RAC: When using RAC with Standard Edition, the processor limits are *per cluster*, not per node. SE-1 licenses cannot be used for RAC at all. SE licenses are valid for RAC, however, the *maximum capacity*of all nodes in your cluster must not add up to more than *4 sockets*. Note: that is *sockets*, not *processors*. The word *socket*is a licensing metric -- and a very tricky one whose meaning varies by the
manufacturer and model of your CPUs.

Sure. The limits are entirely "paper" limits. But if Oracle Corp ever finds you to be violating these paper limits, you might receive a *really*big invoice.

Remember: SE --> $20,000 per socket. EE + RAC --> $70,000 per *core*. Even a small RAC cluster, if non-compliant, can easily cost in excess of $1million to re-license.
