Understanding the Destination Paths of Oracle Products

Each Oracle product that is installed on a machine is installed into an Oracle Home directory or path. This is a directory that contains most of the files associated with the product. This path has a user-supplied name as well. You can specify a name that is intuitive, so you do not have to remember the path. The parent directory of the Oracle Home directory is called the Oracle Base directory or path.

The following table shows some examples of these terms for the installations of an Oracle WebLogic Server, an Oracle database, Oracle JDeveloper, and JD Edwards EnterpriseOne Development Client.

Note:

It is strongly recommended that you always install each Oracle product into its own Oracle Base Path. Attempting to share an Oracle Base Path among multiple Oracle products may cause unforeseen errors either during installation or at runtime.

Oracle Product	Installation Directory	Oracle Base Path	Oracle Home Path	Oracle Home Name
WebLogic Server	`C:\WebLogic\WLS19c`	`C:\WebLogic`	`C:\WebLogic\WLS19c`	WebLogic_Home
JDeveloper	`C:\Oracle2\Middleware`	`C:\Oracle2`	`C:\Oracle2\Middleware`	JDev_Home
JD Edwards EnterpriseOne	`C:\Oracle3\E920`	`C:\Oracle3`	`C:\Oracle3\E920_1`	JDE_E920_Client

During the installation of an Oracle product, OUI copies the files from the package to subdirectories under the Oracle Home path and then performs the necessary configurations. In addition, it places a copy of OUI into the Oracle Home Path.

OUI also creates a submenu of items in the Start / All Programs menu. This submenu is named "Oracle - <Oracle_Home_Name>" where <Oracle_Home_Name> is the name that the user specified during the installation. This submenu will include links to some of the product's programs and the submenu called Oracle Installation Products. Oracle Installation Products includes a link to the copy of OUI that is in the Oracle Home Path. Although you can run other copies of OUI to uninstall (remove) the EnterpriseOne Development Client, it is safest to uninstall using the link in this submenu.
