7 Using Oracle Universal Installer

Oracle Universal Installer (OUI) is the installer used for installing Enterprise Manager Grid Control (Grid Control). OUI is a Java-based graphical user interface application that enables you to install Oracle components from a DVD, multiple DVDs, or the Web.

This chapter describes how you can use OUI. In particular, it covers the following;

Specifying a Temporary Directory
Starting the Installer

Specifying a Temporary Directory

When you start OUI, it automatically copies some executable files and link files into the default /tmp directory (C:\Documents and Settings\<user ID>\Local Settings\Temp on Microsoft Windows) on the machine. If the machine is set to run cron jobs (along with many other processes that may be running) periodically, these jobs attempt to clean up the default temporary directory, thereby deleting some files and causing OUI to fail.

If there are any cron jobs or processes that are automatically run on the machines to clean up the temporary directories, ensure you set the TMP or TEMP environment variable to a different location (than the default location) that is secure on the hard drive (meaning a location on which the cleanup jobs are not run). Also ensure that you have write permissions on this alternative TEMP directory. This must be done before you execute runInstaller (setup.exe on Microsoft Windows).

Note:

Specifying an alternative temporary directory location is not mandatory, and is required only if any cron jobs are set on the computers to clean up the /tmp directory.

Starting the Installer

Start Oracle Universal Installer by running the runInstaller (or setup.exe on Microsoft Windows) from the top-level directory of the DVD.

Alternatively, you can change the directory to the Parent Directory (or the root directory) where you will install the Oracle home, then specify the full path to /runInstaller (setup.exe on Microsoft Windows).

To specify a response file for a silent installation, use the following command:

$ ./<runInstaller or setup.exe> -responseFile <responsefile_location> <optional_parameters> -silent

See Also:

Refer to the Creating and Customizing Response Files chapter of the Oracle Universal Installer and OPatch User's Guide for more information on silent installations.

When you invoke the installer, the installation runs prerequisite checks on the following:

Operating System Version
Operating System Packages
Operating System Patches
User Credentials
TEMP and SWAP space
DISPLAY Colors
Additional Patches
Kernel version
Oracle home is empty
Oracle home space
Physical memory

The list of prerequisite checks that must be executed can be viewed in the initialization parameters file located in the following directory of the product-specific installation:

<DVD>/install/oraparam.ini

If a prerequisite check fails, you are prompted to continue, or stop the installation process. You may install the missing software at this point, or discontinue the installation. Note, however, that you may have newer patches that supersede the required patches.

Once you continue, follow the installation instructions on the screen. At any time while installing Enterprise Manager, you can click Help for information about the pages.
