To create a new database, the following prerequisites must be met:
- There is sufficient memory available to start the Oracle instance.
- There is sufficient disk storage space for the planned database on the computer that executes Oracle.
- The desired Oracle software is installed.
- You have the operating system privileges associated with a fully operational database administrator. You must be specially authenticated by your operating system or through a password file, allowing you to start up and shut down an instance before the database is created or opened.
All of these are discussed in the Oracle installation guide specific to your operating system. Additionally, the Oracle Universal Installer will guide you through your installation and provide help in setting up environment variables, directory structure, and authorizations.
