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.
deinstall tool is a script that you can run separately from Oracle Universal Installer (OUI).runinstaller) or as a standalone tool (deinstall).-paramfile option to use the values you specify in the response file.Grid_home is the Oracle Grid Infrastructure for a cluster home:rootcrs.sh command flags -deconfig -force enables you to unconfigure Oracle Clusterware on one or more nodes without removing installed binaries.
