7 Removing Oracle Database Software

These topics describe how to remove Oracle software and configuration files.

You can remove Oracle software in one of two ways: Use Oracle Universal Installer with the deinstall option, or use the deinstallation tool (deinstall) that is included in Oracle homes. Oracle does not support the removal of individual products or components.

Caution:

If you have a standalone database on a node in a cluster, and if you have multiple databases with the same global database name (GDN), then you cannot use the deinstall tool to remove one database only.
