C.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:

UNIX Systems: Creating the oraInst.loc File
Windows Systems: Creating the Registry Key

C.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:

Log in as the root user.
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:
```
inventory_loc=oui_inventory_directory
inst_group=oui_install_group
```
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.
Exit from the root user.

Note:

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.

C.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
