The most notable change during this process is
that you actually have to run two different Oracle software
installs: one for the cluster ware and then one for the database.
These are two different downloads from the Oracle OTN site. So first
you obtain the Oracle clusterware install files, export ORACLE_HOME
= /home/oracle/product/10.2.0/crs, and then run the clusterwares
installer via the runInstaller script as shown in Figure 12
(next page). If you have done everything to this point correctly,
including setting the /etc/hosts file with all three mandatory RAC
IP addresses, then the installer should recognize this as a
legitimately clusterable node. If not, then backtrack and re-verify
the prior steps done properly.

Running Clusterwares Installer
The first critical step will be the network
interface screen shown in Figure 13. You need it to properly
recognize both of your Oracle public and private network interfaces
and with the proper interface type chosen. It is not uncommon for
this screen to require manual adjustments to the interface type, as
it often comes up with both being private. Just make sure to mark
the correct one as public.

The clusterware install will then ask you for
locations and redundancy nature for the cluster registry (OCR) and
voting disk files which must reside on your shared disk space. Note
that as shown in the next two screen snapshots (Figures 14 and 15),
I have chosen easy names with no redundancy to keep things simple,
i.e. my choices are not really redundant because external implies it
is being done externally and in this case, it is just not being
done at all. This installer will now create and format those files.

Specifying Voting Disk Location
Finally, the clusterware installer will ask for
the nodes in your cluster in which to propagate these same settings.
Since you have only one physical node in your pseudo-RAC
setup, that is all you will see, as shown on the following page in
Figure 16. If you had other actual RAC nodes, you would merely see
additional entries one for each additional node. Now you are done
with the clusterware install process, so on to the Oracle software
install.

Single Node in Pseudo-RAC Setup
You then perform the database install as before
by choosing all the same options as was done in the previous
chapter. To accomplish this task, you export ORACLE_HOME =
/home/oracle/product/10.2.0/db, and then you run the databases
installer via the runInstaller script. With the database
install process, you are now ready to do the database creation. It
is good to note that this might be the right place in which to
shutdown the VMware image and make a backup copy. That way you can
get back to this point easily when you want to refresh your virtual
machine to a prior pristine state.
