Which installation option is used to install into an existing Fusion Middleware Home?

1.4.3 Software Only Install

The Software Only Install type installs software binary files in an existing Middleware home for later configuration. The Middleware home might have been previously created by another Oracle Fusion Middleware product installation (for example, Oracle SOA Suite). Installing binary files into an existing Middleware home is useful if your goal is to have multiple products share the binary files from a common Middleware home.

The Software Only Install type is required to install Oracle Business Intelligence with your own JDK. See Section 4.2.5, “Installing Oracle Business Intelligence 11g with Your Own Java Development Kit (JDK).”

When you select this installation type, Oracle Business Intelligence 11g Installer does not perform any configuration during installation. Instead, after installation, you use the Configuration Assistant to configure the binary files into a new domain and instance home, to scale out, or to extend an empty WebLogic domain. See Section 5.2, “Configuring Oracle Business Intelligence with the Configuration Assistant.”

With obiee12c, the only installation type is the “enterprise installation”: use the jdk 1.8+ to install the fusion middleware home, then install obiee12c with the existing middleware home.

What if there is one existing fusion middleware infrastructure home and the BI is planed to be installed on single computer? I choose Software only install in this case.
