B.2 Before Performing a Silent Installation

This topic describes tasks that may be required before you perform a silent installation. This topic includes the following sections:

B.2.1 UNIX Systems: Creating the oraInst.loc File

The Installer uses the Oracle inventory directory to keep track of all Oracle products installed on the systems. The inventory directory is stored in a file named oraInst.loc. If this file does not already exist on your system, you must create it before starting a silent installation.

Perform the following steps to create the oraInst.loc file if it does not exist:

  1. Log in as the root user.

  2. Using a text editor such as vi or emacs, create the oraInst.loc file in any directory. The contents of the file consist of the following two lines:


    Replace oui_inventory_directory with the full path to the directory where you want the Installer to create the inventory directory. Replace oui_install_group with the name of the group whose members have write permissions to this directory.

  3. Exit from the root user.


After you performing the silent installation on UNIX platforms, you must run the ORACLE_HOME/root.sh script as the root user. The root.sh script detects settings of environment variables and enables you to enter the full path of the local bin directory.

B.2.2 Windows Systems: Creating the Registry Key

If you have not installed Oracle Identity Management on your system, you must create the following Registry key and value:

HKEY_LOCAL_MACHINE / SOFTWARE / Oracle / inst_loc = [inventory_directory]

Replace inventory_directory with the full path to your Installer files. For example: C:\Program Files\Oracle\Inventory
