B.5 Running Oracle Universal Installer Using a Response File

After creating the response file, run Oracle Universal Installer at the command line, specifying the response file you created, to perform the installation.

Run Oracle Universal Installer at the command line, specifying the response file you created. The Oracle Universal Installer executables, runInstaller and gridSetup.sh, provide several options. For help information on the full set of these options, run the gridSetup.sh or runInstaller command with the -help option. For example:

For Oracle Database:
```
$ directory_path/runInstaller -help
```
For Oracle Grid Infrastructure:
```
$ Grid_home/gridSetup.sh -help
```

The help information appears in a window after some time.

To run the installer using a response file:

Complete the preinstallation tasks for a normal installation.
Log in as the software installation owner user.
If you are completing a response file mode installation, then set the operating system DISPLAY environment variable for the user running the installation.

Note:

You do not have to set the DISPLAY environment variable if you are completing a silent mode installation.
To start the installer in silent or response file mode, enter a command similar to the following:
- For Oracle Database:
```
$ /directory_path/runInstaller [-silent] [-noconfig] \
 -responseFile responsefilename
```
- For Oracle Grid Infrastructure:
```
$ Grid_home/gridSetup.sh [-silent] [-noconfig] \
 -responseFile responsefilename
```
Note:

Do not specify a relative path to the response file. If you specify a relative path, then the installer fails.

In this example:
- directory_path is the path of the DVD or the path of the directory on the hard drive where you have copied the installation binaries.
- -silent runs the installer in silent mode.
- -noconfig suppresses running the configuration assistants during installation, and a software-only installation is performed instead.
- responsefilename is the full path and file name of the installation response file that you configured.
When the installation completes, log in as the root user and run the root.sh script. For example
```
$ su root
password:
# /oracle_home_path/root.sh
```
If this is the first time you are installing Oracle software on your system, then Oracle Universal Installer prompts you to run the orainstRoot.sh script.

Log in as the root user and run the orainstRoot.sh script:
```
$ su root
password:
# /u01/app/oraInventory/orainstRoot.sh
```
Note:
You do not have to manually create the oraInst.loc file. Running the orainstRoot.sh script is sufficient as it specifies the location of the Oracle Inventory directory.
