這位學長您好：

Oracle我外行，但我記得他Licence 是算核心的，
如果我是對的，那新CPU核心很可能發生變動，
Lic的$$會變貴很多><

Oracle DB授權是by named user或processor
可參照官方的online store

要提高效能
有很多面向可以去考慮
這樣比較可以把錢花在刀口上

感謝學長指導，經databaselicensing-070584.pdf確認，說明如下：


Processor: This metric is used in environments where users cannot be identified and counted. The Internet is a typical environment where it is often difficult to count users. This metric can also be used when the Named User Plus population is very high and it is more cost effective for the customer to license the Database using the Processor metric. The Processor metric is not offered for Personal Edition. The number of required licenses shall be determined by multiplying the total number of cores of the processor by a core processor licensing factor specified on the Oracle Processor Core Factor Table which can be accessed at http://oracle.com/contracts. All cores on all multicore chips for each licensed program are to be aggregated before multiplying by the appropriate core processor licensing factor and all fractions of a number are to be rounded up to the next whole number. When licensing Oracle programs with Standard Edition One or Standard Edition in the product name, a processor is counted equivalent to a socket; however, in the case of multi-chip modules, each chip in the multi-chip module is counted as one occupied socket.

oracle要最佳化，內建的就很好用了
開個dbconsole，找tuning advisor出來看歷史紀錄
當然，原則上DB類的往storage投入20%經費，都遠遠好過向CPU投入80%
除非這台專跑超複雜DW語法，那考慮的又是另一個面向了
