Deinstalling Oracle Components with Oracle Universal Installer

Deinstalling Oracle Components with Oracle Universal Installer

This section describes how to use Oracle Universal Installer to deinstall Oracle components (which deinstalls them from the Oracle Universal Installer inventory) instead of removing them manually. If you delete an Oracle Home manually (for example, by deleting the directory structure with Windows 98 Explorer), the components in that Oracle Home remain registered in the Oracle Universal Installer inventory. If you then attempt an installation in the same Oracle Home, some or all of the components selected may not be installed because Oracle Universal Installer determines they are already installed.

Note: Manual removal of components is permitted only if you exit Oracle Universal Installer during an installation. For example:

In these cases, Oracle Universal Installer does not register the installation in its inventory. However, files may have been copied to your Oracle Home. Remove these files manually and restart the installation.

Task 1: Deinstall Database, Net8 Components and Registry Entries

If you want to deinstall the Oracle8i database (and its data files) and/or Net8 Client and Net8 Server components, you must first stop those by following these steps. If you do not want to deinstall these components, go to step "Task 2: Deinstall Components with Oracle Universal Installer".

Oracle Universal Installer creates registry entries for Oracle components during installation. However, Oracle Universal Installer does not delete registry entries created by Oracle Database Configuration Assistant and Net8 Configuration Assistant.

To deinstall database, Net8 components and registry entries:

1.If any database instance is running, stop it by right clicking on the database icon in systray and then selecting "Oracle8i Shutdown".

2.To stop the listener, execute the following command at MS-DOS prompt:

C:>lsnrctl stop
