Checking Prerequisites


Before the installation process, Oracle performs a number of automated prerequisite checks to ensure that your machine fulfills the basic hardware and software requirements for an Oracle install. If your machine does not meet any of the requirements, an error message is displayed. The requirements may vary somewhat depending upon the type of machine and operation system Oracle DBA are running, but some examples of prerequisite checks include:

A minimum of 512 MB of memory is available

Sufficient paging space is available.

Appropriate operating system service packs or patches are installed.

Appropriate files system format is being used.

The installer automatically sets any operating system environment variables that the Oracle database server requires for its operation. The Oracle Universal Installer guides Oracle DBA through an interview phase that asks Oracle DBA to specify your choices for installation and database creation. The exact sequence of pages depends on your platform. All platforms include the following choices:

What database product do Oracle DBA want to install?

Oracle DBA can install one of the following:

Oracle Enterprise Edition—Oracle’s most full featured database product providing data management for high-end applications.
Oracle Standard Edition—A less-expensive and somewhat scaled down version of the Oracle database suitable for workgroup or department level applications
Custom Install—Allows Oracle DBA to customize the Enterprise Edition by selecting products to install. Do this if Oracle DBA want to add a component to your database that would not normally be installed or prevent certain components from being installed.
