6.5.1 Changing the Current Setting for Oracle Home

Use Oracle Universal Installer (OUI) to change the current Oracle home.

This procedure changes the value of the default ORACLE_HOME variable in the registry to the value you selected. It also ensures that the %ORACLE_HOME%\bin directories for each product are listed in the correct order in your PATH environment variable.
  1. Start the Oracle Universal Installer.
  2. Click the Installed Products button.
  3. Click the Environment tab at the top of the window.
  4. Move the Oracle home directory that you want as your default to the top of the list.
  5. Apply the changes, and exit the installer.
