The company now treats each core on a multicore processor as three-quarters of a chip when calculating license costs for its database and application server products, according to the latest licensing terms posted on its Oracle Store Web site.
Oracle has changed its database and middleware pricing for multicore processors, treating each core as three-quarters of processor.
The licensing change, which had been anticipated for months, will please customers, according to analysts and partners. But Oracle is still charging a premium compared with the policies from database rivals IBM and Microsoft.
Until recently, Oracle's policy was to treat each core as a separate processor, a stance that was at odds with most other large software providers' policies.
Major infrastructure software companies, including, Red Hat and Novell, have a policy that treats a multicore chip as a single processor for calculating license fees.
In April,and now treats dual-core chips from Advanced Micro Devices and Intel as a single processor. But it continues to treat each core as a processor for IBM's own Power chips.
After IBM, Oracle remained the last holdout among large software companies to stick to a policy of treating each core as a processor, said Julie Giera, an analyst at Forrester Research.
"Oracle had to (change) competitively," Giera said. "They've been taking advantage of customers, frankly, by charging full price for these cores even though in dual and multicore chips you're not getting full capacity."
Giera said the change will likely soothe some irritation and dissatisfaction among Oracle customers.
Multicore processors pack more than one processing unit, or core, on a piece of silicon. The technique boosts performance of a machine, while keeping the heat generation down, although two cores do not double the performance.
Dual-core systems are expected to become more common since Intel and AMDearlier this year. Server chips with several cores are already on the market from the likes of IBM and Sun Microsystems.
Server software products historically have used a per-processor license fee, a method that'sby the emergence of new technologies.
Traditional per-processor pricing means a customer could pay substantially more when buying a database or application server to run on a server with multicore chips if each core is considered one processor.
Michael McDermott, chief operating officer of Cisco Inc., which resells Oracle software, called the change a "step in the right direction."
He said that the issue of dual-core pricing has come up with a client looking at a large installation of clustered Oracle databases. Oracle's discount would create a substantial savings from a licensing standpoint, McDermott said.
"When we heard about IBM's policy, we were thinking that Oracle would change too," he said. "Maybe they'll get more pressure to do like everyone else."
Oracle has faced some public criticism for its former policy.
At the Oracle OpenWorld customer conference last December, Sun CEO, predicting that the company would change its policy. McNealy referred to Sun's planned dual-core Opteron servers as a "big revenue opportunity for Oracle with their dual-core pricing."
Like Sun, chip manufacturers Intel and AMD have been vocal proponents of a "per socket" pricing, which would treat several cores as one processor.
Meanwhile, BEA Systems, like Oracle, has decided to charge a premium for its software that runs on dual-core servers. In
