The first level of learning Oracle for beginners: correctly installing the Oracle database

Oracle database is an object-relational database. Based on the relational database, some object-oriented features are introduced. Oracle database products can be downloaded for free, and its services are chargeable. That is, when the database is used for commercial purposes, it must be authorized by Oracle. Oracle has been around for 30 years and has gone through many versions. The latest version is 12c. The 11g version is currently relatively stable and is also used by many companies, so we will start learning from this version, and there will basically not be much difference in subsequent versions.

PS: MySQL is a commonly used database for Java development. MySQL's parent company was acquired by SUN in 2008, and SUN was acquired by Oracle in 2009, so MySQL is also a product of Oracle.

Step 1: First go to the Oracle official website to download the Oracle database installation package, and extract the two files together into the same folder in the same directory. Do not include Chinese characters in the path name. There should also be no irregular characters such as spaces. After decompression is completed, go to the corresponding path, find [setup.exe], double-click to run, and install Oracle 11g.

Step 2: Configure security Update: You can fill in your email address in this step (or you can leave it blank and just receive some useless emails). Uncheck "I want to receive security updates through My Oracle Support (W)" below.

Step 3: Security options: Directly choose to create and configure a database by default (after installing the database management software, the system will automatically create a database Example), as shown in the figure.

Step 4: System class: Just select the default desktop class, as shown in the figure.

Step 5: Typical installation: This step is an important step.

It is recommended that you only need to update the Oracle base directory, and the directory path should not contain Chinese or other special characters.

The global database name can be defaulted, and the password must be remembered. The password rules recommended by Oracle must be uppercase letters plus lowercase letters plus numbers, and must be more than 8 characters, as shown in the figure.

Step Six: Prerequisite Check: In this step, the installation program will check whether the computer's software and hardware system meets the minimum requirements for installing this Oracle version. Just take the next step.

Step 7: Complete the installation, as shown in the figure.
