This blog shows you how to install the Oracle Database 11gR2 software on Microsoft Windows along with a default instance of an Oracle Database that contains example schemas ( including the HR schema)

Hardware and Software Requirements

Before installing the software, Oracle Universal Installer (OUI) performs several automated checks to ensure that your computer fulfills the basic hardware and software requirements for an Oracle Database installation. If your computer does not meet the requirements, an error message is displayed. Some of the requirements to install the software are:

  • Minimum 2 GB of physical memory
  • Sufficient virtual memory (swap)
  • At least 10 GB of free disk space
Let’s see how the database can be installed on the windows machine.
1) Expand the database folder where you have extracted the database. Double-click setup.exe

2) The Configure Security Updates window appears. Enter your email address and My Oracle Support password to receive security issue notifications via email. If you do not wish to receive notifications via email, deselect “I wish to receive security updates via My Oracle Support“. Click Next to continue. Click “Yes” in the confirmation window to confirm your preference.

3) The Download Software Updates window appears with the following options:

  • Select “Use My Oracle Support credentials for download” to download and apply the latest software updates. 
  • Select “Use pre-downloaded software updates” to apply software updates that you previously downloaded. 
  • Select “Skip software updates” if do not want to apply any updates. 

Accept the default and click Next.

4) The Select Installation Option window appears with the following options:

  • Select “Create and configure a database” to install the database, create the database instance and configure the database
