You can configure the new Oracle Database 12c Release 1 De-configuring Listener configuration file Downloading the Deinstallation Tool for Use with Failed Installations If you require the deinstallation tool deinstall to remove failed or incomplete installations, then it is available as a separate download from the Oracle Technology Network OTN Web site. When you run deconfig with this flag, it deconfigures and deinstalls the Oracle software on the local node the node where deconfig is run. Bill Fane.
