Going off the base price list for Oracle, a processor license for Oracle Standard is $17,500 a processor. Now they detail that a processor is determined by the number of cores of the processor multiplied by a core processor licensing factor. Looking at the table that is currently 0.5 for Xeon chips. That means that each CPU you have will classify for 3 Oracle processor licenses, now as you have 2 CPU's you need 6. So thats a cost of $105000 right off the bat and it doesn't include SA. Add in SA its an extra $23100, unsure if thats a year, 1 off cost.

So still think SQL is expensive?
