1. Log in as the 'oracle' user.  Confirm that your ORACLE_HOME,
   ORACLE_SID, and PATH variables do not refer to any previous
   installation of Oracle (such as 10g).  Set your ORACLE_BASE
   environment variable.

     env | grep -i oracle
     unset ORACLE_HOME
     unset ORACLE_SID
     # Manually set PATH, leaving out old ORACLE_HOME/bin
     export ORACLE_BASE=/u01/app/oracle

2. Change to the directory containing the Oracle 11g Database
   installation media (your path may be different).

     cd /disks/11g/database

3. Start the Universal Installer.

     ./runInstaller

4. When the "Select Installation Method" page appears, select
   "Advanced Installation".
   After choosing Enterprise Edition on the "Select Installation
   Type" page, review the ORACLE_BASE and Software Location settings
   on the "Install Location" page.  (Note: if the installer
   displays the 10g ORACLE_HOME, you probable didn't unset your
   ORACLE_HOME environment variable; if so click "Cancel" to exit the
   installer, unset ORACLE_HOME and ORACLE_SID, and remove the old
   ORACLE_HOME/bin from your PATH environment variable; run the
   installer again.)

5. After the Product Specific Prerequisite Checks complete, examine
   any errors or warnings.
   a. The overall result should be "PASSED".
   b. Work with your instructor on any warnings or errors you
      cannot resolve on your own.
   NOTE: On certain platforms, if the system currently has Oracle
         Database 10g installed, you may get this error:
           OUI-10150: Error: The directory you specified for the
           database files is already in use with the given global
           database name, orcl (... etc. ...).
         Ignore the radio buttons, and click OK.
         We aren't installing the database at this time.

6. On the "Upgrade an Existing Database" page, select No.

7. On the "Select Configuration Option" page, select "Install
   Software Only".  Do NOT create a database.

   Note: If you didn't create a separate 'asmadmin' group, or if
         you didn't give the 'oracle' account membership in any of
         the 'dba', 'oper', or 'asmadmin' groups, you will be prompted
         to specify which OS groups are Oracle-privileged groups.

8. When the "Summary" screen appears, click 'Install'.

9. When prompted, login as 'root' and run the root.sh script.
   a. Accept the default value for the full path name.
   b. Reply 'Y' to all remaining prompts (the default is No).

10. Return to the installer and exit.
