Chapter 33.
Starting runInstaller
An important point to note...
If you use CDs to install the database, do not change directory (cd) to /mnt/cdrom to
execute ./runInstaller! If you do so, the installation will fail because you will not be
able to change the CDs.
Before you continue, make sure you have set the Oracle environment variables in
"Setting Oracle Environment
Oracle no longer supports a character mode installer. Therefore, in order to execute runInstaller
directly from a console of a machine you are logged into you need to set the DISPLAY environment
variable. In the example the name of the node where Oracle is running is called "oracleserver".
First, make sure that you also allow runInstaller on "oracleserver" to display X information
on your Linux desktop machine. In the example, the computer name where you are running an X
Windows desktop like KDE or GNOME is called "yourdesktop". Programs running on remote
machines cannot display information to your screen unless you give them the authority to do so.
Before you execute runInstaller, execute xterm (or another terminal client of your choice) to see
if your X setup is really working. If you are about to install Oracle on your desktop PC and not on a
remote node, then you can skip step 1 and 3.
Step 1: Allow "oracleserver" to display X information to your desktop PC "yourdesktop":
yourdesktop:user$ xhost +oracleserver
Step 2: Open a new window and log in to the Oracle server "oracleserver" as the root user. This
window will be used to mount and unmounting the Oracle CDs.
oracleserver:$ su - root
oracleserver:root# mount /mnt/cdrom
Step 3: From the console of your Oracle server "oracleserver" where you will run runInstaller,
execute the following commands:
oracleserver:$ su - oracle
oracleserver:oracle$ export DISPLAY=yourdesktop:0.0
Step 4: Now you can execute runInstaller as "oracle" as shown in the next chapters. It is
important that you do not change directory (cd) to /mnt/cdrom.
oracleserver:oracle$ /mnt/cdrom/runInstaller
Variables".
