How Oracle databases Authorize charges (database Licensing)

Oracle software itself is free, so anyone can download and install Oracle's database software from Oracle's official website, at a charge of license, which is software licensing, and if the database is for commercial use, it is necessary to purchase the license of the corresponding Oracle product.

Oracle now has two modes of authorization, per CPU (Process) and per user (Named user Plus). The former is typically used in situations where the number of users is uncertain or the number of users is large, typically such as the Internet environment, and the latter is usually used to determine or lower the number of users.

by CPU: License number of =CPU * coefficients. The coefficients are from an Oracle parameter table, such as the IBM POWER6 processor for 1,AMD and Intel processors of 0.5, see below for details:

parameters	processor model
0.25	sun UltraSPARC T1 processor
0.50	s UN UltraSPARC T1 processor
0.50	intel , AMD processor
0.50	sun UltraSPARC T2 + Processor
1.00	IBM POWER6, POWER7 Place Manager
0.75	other multicore processors
1.00	single-core processor

According to the formula, a 4*8 core processor of a sun UltraSparc T1 needs to 4*8*0.25=8 a CPU licenses

by User : The official definition of the number of Oracle users is that every user who accesses an Oracle database, whether natural or device (such as sensors in an industrial environment), is counted as a user (Named user).

Official English definition: Named User Plus:is defined as an individual authorized by-use the programs which is installed on a single Server or multiple servers, regardless of whether the individual is actively using the programs at any given time. A non human operated device would be counted.

According to the number of users to purchase the corresponding product has the corresponding license minimum purchase limit, as follows:

oracle database standard Edition one

product	minimum license
5 Named User Plus licenses
oracle Database standard Edition	5 Named User Plus licenses
oracle Database enter Prise edition	25 Named User Plus licenses per CPU
oracle application Server standard Edition one	5 Named User Plus Licenses
all other Oracle application servers products	10 Named User Plus licenses per CPU

Of course, users should be ordered according to their actual number of users, and not less than the minimum number of users required by the corresponding version.

In general, the cost of 1CPU is approximately equal to the cost of 50user, so if the number of users >cpu * coefficient of *50, then the CPU ordered by the more economical.

Each License also has a classification of the validity period [whether the user License or CPU License], respectively: 1 years, 2 years, 3 years, 4 years, 5 years, permanent. Of course, the price is increased in turn.

Current Oracle 11G User License Unlimited lifetime price of about 3,500, 50 User License Unlimited use of the purchase amount is 175,000, each CPU license unlimited lifetime price of 179,000, The purchase price is 179,000, and the price of 50 user license is close, as calculated by the IBM small Machine factor.

About service prices: In general, the license of Oracle are included in the first-year service charge, which is calculated at 22% of the annual price.
