Contents of the Oracle Home Environment

The Oracle home directory is located under the Oracle base directory.

For example, in a default Windows installation, if you name the Oracle home directory dbhome_1, it appears in the Oracle base directory as follows:

DRIVE_LETTER:\app\username\product\18.0.0\dbhome_1

where username is the installation user if you choose a Windows Built-in Account, else it is the Oracle Home User specified.

An Oracle home corresponds to the environment in which the Oracle components run. This environment includes the following:

• Location of the installed component files

• PATH variable pointing to the binary files of the installed components

• Registry entries

• Service names

• Program groups

Oracle homes also have a name associated with them, which is automatically assigned by the installer.
