The Oracle Database Client software is available on the Oracle Technology Network (OTN) website. In most cases, Oracle Universal Installer provides a graphical user interface (GUI) to install the software.

However, you can also use the Oracle Universal Installer to complete silent or response file installations, without using the GUI.

• Creating the Oracle Base Directory
  If you install Oracle Database Client on a computer with no other Oracle software installed, Oracle Universal Installer creates an Oracle base directory for you.
• Multiple Oracle Home Components
  You can install all Oracle components in multiple Oracle homes on the same computer.
