Oracle Home Directory Naming Convention

By default, Oracle Universal Installer configures Oracle home directories using these Oracle Optimal Flexible Architecture conventions.

The directory pattern syntax for Oracle homes is /pm/s/u/product/v/type_[n]. The following table describes the variables used in this syntax:

Variable	Description
pm	A mount point name.
s	A standard directory name.
u	The name of the owner of the directory.
v	The version of the software.
type	The type of installation. For example: Database (`dbhome`), Client (`client`), or Oracle Grid Infrastructure (`grid`)
n	An optional counter, which enables you to install the same product more than once in the same Oracle base directory. For example: Database 1 and Database 2 (`dbhome_1`, `dbhome_2`)

For example, the following path is typical for the first installation of Oracle Database on this system:

/u01/app/oracle/product/19.0.0/dbhome_1

Note:

Oracle home or Oracle base cannot be symlinks, nor can any of their parent directories, all the way to up to the root directory.
