To install the Oracle RAC database using the Oracle Universal Installer

1. Log in as the Oracle user. On the first node, set the DISPLAY variable.

   • For Bourne Shell (bash), type:

     $ DISPLAY=10.20.12.150:0.0;export DISPLAY

   • For C Shell (csh or tcsh), type:

     $ setenv DISPLAY 10.20.12.150:0.0

2. Start the Oracle Universal Installer.

   $ cd /dvd_mount

   $ ./runInstaller

3. Enter the following information when prompted by the Oracle Universal Installer:

   Select installation type	Select Enterprise Edition.
   Specify home details	Review or enter the ORACLE_HOME and ORACLE_BASE directory paths.
   Specify Hardware Cluster Installation Mode	Select Cluster Installation. Select the nodes on which you want to install the Oracle RAC database software.

   The Oracle Universal Installer runs a product-specific prerequisite check. Any items that are flagged must be manually checked and configured.

4. On the Select Configuration Option screen, select the option Install database software only.

   Note:

   Do not select the option Create a database. Symantec recommends that you create the database later

5. Review the configuration summary presented by the Oracle Universal Installer. The Oracle Universal Installer begins the Oracle database installation.

6. Run the root.sh script as prompted by the Oracle Universal Installer.

   # cd $ORACLE_HOME

   # ./root.sh
