From the root directory of the database installation files, run the script ./runInstaller as
the oracle user, just as you did for the CRS install. The first screen you will see after the welcome
screen, the Oracle inventory location screen, and the Installation Type screen is shown in
Figure 10-8.

Although you can install the software in any directory, make sure that this directory is available
to the user oracle on all nodes in the cluster. In addition, make sure that this directory is not the
same as the CRS installation directory.
As shown in Figure 10-9, if the installer detects clustering software running on the node, it
gives you the option to install the software on the entire cluster or to perform a single-instance
install. In this case, you select all the nodes you configured earlier as part of the cluster.
After you select the nodes for your RAC database instances, the installer confirms that the
environment for the Oracle Database software is configured correctly, as you can see in Figure 10-10.
The screen in Figure 10-11 gives you the option to create the database immediately, configure
ASM, or install the database software only. As I mentioned earlier in this chapter, I??™m going to
install the software first, and then use the Database Configuration Assistant (DBCA) to configure
an ASM instance on each node and create the shared database.
