Oracle license and license usage Problems

1. Differences between genuine Oracle products and pirated products
Go straight to the topic, which is a lot of research and development attention. For commercial use (that is, you are not at home or playing on your own), strictly speaking, it is the difference between a license paper. No matter when the downloaded version is used, you can create a database and perform normal development. However, if it is used for commercial purposes, it is an illegal action. As for the expensive price, a large part of the cost is actually maintenance. In addition, the downloaded version cannot be patched (it does not mean that you cannot download it, but you do not have an account to download it, in addition, it is illegal to install patches for the free version. The official version has a product service code that can be used for online services, upgrades, and so on. In addition, different on-site services can be provided based on your purchase. As for the price of each version, it is indeed different. You can consult the agent. As far as I know, it should be the cheapest version of win, but it is also the most unstable.

2. Can you tell us the characteristics and differences between the Personal Edition, Standard Edition 1, Standard Edition and Enterprise Edition?
A: in short,
1. Standard Edition 1 (one) is applicable to servers with 1 to 2 CPUs. It offers great price advantages, but only for single-host environments. It is applicable to entry-level applications for small and medium users;
2. Standard Edition is applicable to 1-4 CPU servers, including 4-CPU Single Server or 2 dual-CPU servers. It can be used for dual-host hot backup or RAC, and the price is moderate, applicable to applications at the working group level and department level for large and medium-sized users who have further requirements on database performance and security;
3. Enterprise Edition is applicable to single-host, dual-host, multi-CPU, multi-node clusters, and other environments with complete functions, but the cost is high, it is suitable for large-scale enterprise-level and high-end enterprise-level applications with high database performance and reliability requirements. For more information about the functional modules, see Oracle Database whitepaper.

3. What is the Oracle ordering method?
A: There are two ways to order by number of users and by CPU, in which the order by CPU is also called the unlimited user version.

4. What is the official definition of oracle users?
A: Every user accessing the Oracle database, whether it is a natural person or a device, is counted as a user (named user ).
Official English definition: named user plus: is defined as an individual authorized by you to use the programs which are 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 will be counted.

5. How does one calculate the number of oracle users?
A: The minimum number of users of Oracle official versions is:
Individual version: 1 user * PC count
Standard Edition 1 = number of servers x 5
Standard Edition = server CPU x 10 Users
Enterprise Edition = server CPU x 25 users;
Users should order according to their actual number of users, and not less than the minimum number of users required by the corresponding version.

6. Could you give an example?
A: For example, if your application is based on the Internet and Oracle acts as the website background database, according to Oracle's official definition of the number of users, each website (database) accessed through the Internet) is counted as one user, so the number of users is large and unpredictable, so you should order according to the number of CPU.

7. Do Internet or B/S architecture applications have to be subscribed to by CPU?
A: Not necessarily. If the number of users accessing the Oracle database is predictable and the number of users is small (<server CPU x 50), you can also order the number of users.

8. Can I provide a trial version? How long is the trial term?
A: After your subscription is made, you can provide a trial version for free trial and evaluation. The trial period is one month. If you do not place an order after the trial period, you must uninstall and delete the installed Oracle trial software from the system.

9. Maximum number of concurrent users of Oracle DBMS.
To put it bluntly, there are eight lanes of roads. No matter how many cars are there, only eight cars can walk side by side. No matter how many connection requests you want to access the database, the maximum number of concurrent requests is exceeded and cannot be reached. Generally, Oracle supports a maximum of 150 users, that is, the maximum number of concurrent users is 150. It is usually not used up unless your system has a very high access load. The number of users is calculated based on the CPU clock speed at the time of purchase. Oracle imposes a mandatory requirement on the number of users to earn money. Avoid tax evasion.

10. Summary
Generally speaking, Oracle refers to connecting to DBMS, not DB. No matter how many DBs you have, Your DBMS can only have one, so it actually refers to how many people on your network can access your DBMS at the same time. In fact, the general selling of software is not so true, as foreign software is generally sold in China to buy a general license, for example, you estimate that you may have a maximum of 20 concurrent workers, you can buy 10 general software vendors, and these software vendorsProgramThere are no internal restrictions, just legal issues. The number of users you buy is relatively small, or you only buy the Standard Edition, will only affect your purchase of optional items, such as you want to buy RAC, oracle limits that you have to purchase more than 50 users to purchase RAC. Otherwise, it will not sell.
