How to create a new database in Oracle?

To create a new database in Oracle, you need to follow the following steps:

1. To install the Oracle database software, first, you need to download and install the Oracle database software that is suitable for your operating system from the official Oracle website.
2. To create a database instance: After installation is complete, a default database instance will be automatically generated. You can use Oracle’s “Database Configuration Assistant” to create a new database instance. Simply run the assistant, choose the “Create Database” option, and follow the wizard’s instructions.
3. Configure database parameters: When creating a database instance, you will need to specify certain parameters such as the database name, character set, memory size, etc. These parameters can be configured by editing Oracle’s parameter file (init.ora file).
4. Start the database: Following the creation and configuration of the database instance, you can use Oracle’s “Database Control” or “SQL*Plus” tools to start and manage the database.

Please note that the above steps are only applicable for creating a new database in the case where Oracle database software is already installed. If you need to install Oracle database software, please refer to the official Oracle documentation or seek guidance from professionals.
