Oracle Deinstallation (Deinstall)

You can run the deinstall command from an Oracle home directory after installation.

Purpose

deinstall stops Oracle software, and removes Oracle software and configuration files on the operating system for a specific Oracle home.

Syntax

The deinstall command uses the following syntax:

(./deinstall [-silent] [-checkonly] [-paramfile complete path of input response file] 
[-params name1=value name2=value . . .] 
[-o complete path of directory for saving files] 
[-tmpdir complete path of temporary directory to use] 
[-logdir complete path of log directory to use] [-help]

Parameters

Parameter	Description
-silent	Use this flag to run `deinstall` in noninteractive mode. This option requires one of the following: A working system that it can access to determine the installation and configuration information. The `-silent` flag does not work with failed installations. A response file that contains the configuration values for the Oracle home that is being deinstalled or deconfigured. You can generate a response file to use or modify by running the `deinstall` command with the `-checkonly` flag. `deinstall` then discovers information from the Oracle home to deinstall and deconfigure. It generates the response file that you can then use with the `-silent` option. You can also modify the template file `deinstall.rsp.tmpl`, located in the `$ORACLE_HOME/deinstall/response` directory.
-checkonly	Use this flag to check the status of the Oracle software home configuration. Running `deinstall` with the `-checkonly` flag does not remove the Oracle configuration. The `-checkonly` flag generates a response file that you can use with the `deinstall` command and `-silent` option.
-paramfile complete path of input response file	Use this flag to run `deinstall` with a response file in a location other than the default. When you use this flag, provide the complete path where the response file is located. The default location of the response file is `$ORACLE_HOME/deinstall/response`.
-params [name1=value name2=value name3=value . . .]	Use this flag with a response file to override one or more values to change in a response file you have created.
-o complete path of directory for saving response files	Use this flag to provide a path other than the default location where the response file (`deinstall.rsp.tmpl`) is saved. The default location of the response file is `$ORACLE_HOME/deinstall/response` .
-tmpdircomplete path of temporary directory to use	Use this flag to specify a non-default location where `deinstall` writes the temporary files for the deinstallation.
-logdircomplete path of log directory to use	Use this flag to specify a non-default location where `deinstall` writes the log files for the deinstallation.
-local	Use this flag on a multinode environment to deinstall Oracle software in a cluster. When you run `deinstall` with this flag, it deconfigures and deinstalls the Oracle software on the local node (the node where `deinstall` is run). On remote nodes, it deconfigures Oracle software, but does not deinstall the Oracle software.
-help	Use this option to obtain additional information about the command option flags.
