Oracle Deinstallation (Deinstall)

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] [-local] [-skipLocalHomeDeletion] [-skipRemoteHomeDeletion] [-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 `deinstall` 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 `$ORACLE_HOME/deinstall/response` directory.
-checkonly	Use this flag to check the status of the Oracle software home configuration. Running `deinstall` with the `-checkonly` flag does not remove the Oracle configuration. The `-checkonly` flag generates a response file that you can then use with the `deinstall` command and `-silent` option.
-paramfile complete path of input response file	Use this flag to run `deinstall` with a response file in a location other than the default. When you use this flag, provide the complete path where the response file is located. The default location of the response file is `$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` .
-tmpdir complete path of temporary directory to use	Use this flag to specify a non-default location where `deinstall` writes the temporary files for the deinstallation.
-logdir complete 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.
-skipLocalHomeDeletion	Use this flag in Oracle Grid Infrastructure installations on a multinode environment to deconfigure a local Grid home without deleting the Grid home.
-skipRemoteHomeDeletion	Use this flag in Oracle Grid Infrastructure installations on a multinode environment to deconfigure a remote Grid home without deleting the Grid home.
-help	Use this option to obtain additional information about the command option flags.
