Oracle instance database installation
Oracle database is a widely used relational database management system that is widely used in enterprise applications. Its installation and use are relatively complex and require certain professional knowledge and skills. This article will introduce the specific steps and matters needing attention when installing an Oracle instance database on a Windows operating system.
- Download Oracle database
First, you need to download the installation program of the Oracle database from the Oracle official website. On the download page, select the corresponding version as needed, such as Enterprise Edition, Standard Edition, Development Edition, etc. At the same time, you also need to choose the corresponding platform and operating system, such as Oracle 12c Enterprise Edition under Windows 64-bit operating system.
- Install Oracle Database
After the download is completed, double-click the installer to start the installation. After accepting the license terms, select the installation type. Choose a default installation or a custom installation according to your needs. After filling in the host name, port number, password and other information as required, click Next to start the installation.
- Create an Oracle instance
After the installation is complete, you need to create an Oracle instance. Select Oracle Installation Manager in the startup menu, right-click and select "New", enter the instance name, and select the corresponding Oracle version and database operating mode. It should be noted here that if it is for testing purposes, you can choose single instance mode, otherwise you should choose cluster mode. In addition, you also need to set the listener port, such as the default port 1521.
- Configure Oracle instance
After creating the instance, you need to perform corresponding configuration, such as modifying the default access method, number of client connections, etc. In addition, table spaces, data files, log files, etc. need to be configured. After the instance configuration is completed, restart the instance to make the configuration take effect.
- Database connection and management
After the Oracle instance is successfully configured, you can connect to the database for data operations. You can connect through Oracle's own command line tool SQL*Plus or other third-party management tools, such as PL/SQL Developer. After the connection is successful, management operations such as user management, backup and recovery, and data import and export can be performed.
Summary:
The installation and configuration of Oracle instance database is relatively complex and requires certain professional knowledge and skills. You need to download the installation program from Oracle's official website, select the version, operating system, and platform as needed and install it. After the installation is complete, you need to create an instance, configure the instance, and connect and manage it. In addition, you also need to pay attention to security issues such as setting listener ports and instance access permissions.
