This chapter describes how to completely remove all Oracle databases, instances, and software from an Oracle Real Application Clusters (Oracle RAC) Oracle home directory.
This chapter contains the following topics:

The product-specific documentation if you want to remove a single product to ensure that you are aware of requirements and restrictions that apply for that productThe Deinstallation tool removes Oracle Clusterware and Oracle Automatic Storage Management (Oracle ASM) from your server, as well as Oracle Real Application Clusters (Oracle RAC) or standalone Oracle Database installations. The deinstall tool performs the follows actions when removing software from an Oracle home directory:
Identifies all instances associated with the Oracle home
Shuts down processes
Removes listeners installed in the Oracle Database home
Removes database instances
Removes Oracle Automatic Storage Management and Oracle Clusterware
Note:
You cannot remove or uninstall the Oracle Database Vault option. However, you can disable it. Refer to Oracle Database Vault Administrator's Guide for more details.
You can remove Oracle Configuration Manager. Refer to Oracle Configuration Manager Installation and Administration Guide for more details.
You cannot remove or uninstall Oracle ASM separately from Oracle Clusterware or install it in a location outside of the Grid infrastructure home with Oracle Database 11g release 2 (11.2).
Caution:
If any cluster member node has more than one database with the same global database name (GDN) on a server, then you cannot use the
deinstall.bat tool to remove one database only. For example, if you have a standalone database on one of your cluster nodes with the GDN mydb.example.com, and your Oracle RAC database GDN is also mydb.example.com, then both databases on that node are removed.The following sections describe the script, and provide information about additional options to use the tool:
The Deinstallation Tool (deinstall.bat) is available in the installation media before installation, and is available in Oracle home directories after installation in the directory %ORACLE_HOME%\deinstall. The Deinstallation tool is also available for download from Oracle TechNet (http://www.oracle.com/technology). You can download it with the complete Oracle Database 11g release 2 software, or as a separate archive file.
The deinstall.bat command uses the information you provide, plus information gathered from the software home to create a parameter file. You can alternatively supply a parameter file generated previously by the deinstall.bat command using the -checkonly flag and -o flag. You can also edit a response file template to create a parameter file.
The Deinstallation tool stops Oracle services, instances, and processes, and removes Oracle software and configuration files on the operating system for a specific Oracle home. At the end of the deinstallation process you are prompted to run the rootcrs.pl script as a user that is a member of the Administrators group.
The deinstall.bat command uses the following syntax, where variable content is indicated by italics:
deinstall -home complete path of Oracle home [-silent] [-checkonly] [-local] [-paramfile complete path of input parameter property file] [-params name1=value name2=value . . .] [-o complete path of directory for saving files] [-help | -h]
The options are:
-home
Use this flag to indicate the home path of the Oracle home that you want to check or deinstall. To deinstall Oracle software using the Deinstallation tool located in the Oracle home being removed, provide a parameter file a location outside the Oracle home, and do not use the -home flag.
If you run deinstall from the Oracle_home\deinstall path, then the -home flag is not required because the tool knows from which home it is being run. If you use the standalone version of the tool, then -home is mandatory
-silent
Use this flag to run the command in noninteractive mode. If you use the -silent flag, then you must use the -paramFile flag, and provide a properties file that contains the configuration values for the Oracle home that you want to deinstall or deconfigure.
You can generate a properties file to use or modify by running deinstall.bat with the -checkonly flag. The deinstall.bat command then discovers information from the Oracle home that you want to deinstall and deconfigure. It generates the properties file, which you can then use with the -silent option
You can also modify the template file deinstall.rsp.tmpl, located in the response folder of the Deinstallation tool archive or installation.
-checkonly
Use this flag to check the status of the Oracle software home configuration. Running the command with the checkonly flag does not remove the Oracle configuration. The checkonly flag generates a properties file that you can use with the deinstall.bat command.
When you run checkonly to generate a properties file, you are prompted to provide information about your system. You can accept the default value the tool has obtained from your Oracle installation, indicated inside brackets ([]), or you can provide different values. To accept the defaults, click Enter.
-local
Use this flag on a multinode environment to deconfigure Oracle software in a cluster.
When you run deinstall.bat with this flag, it deconfigures and deinstalls the Oracle software on the local node (the node on which you run deinstall.bat). On remote nodes, it deconfigures Oracle software, but does not deinstall the Oracle software.
-paramfile complete path of input parameter property file
This is an optional flag. You can use this flag to run deinstall.bat with a parameter file in a location other than the default. When you use this flag, provide the complete path where the parameter file is located.
The default location of the parameter file depends on the location of the Deinstallation tool:
From the installation media or stage location: <Drive>:\staging_location\deinstall\response
From a unzipped archive file downloaded from OTN: <Drive>:\ziplocation\deinstall\response, where <Drive>:\ziplocation refers to the directory in which the downloaded archive file was extracted.
After installation, from the installed Oracle home: %ORACLE_HOME%\deinstall\response
-params [name1=value name2=value name3=value . . .]
Use this flag with a parameter file to override one or more values that you want to change in a parameter file you have already created.
-o complete path of directory for saving response files
Use this flag to provide a path other than the default location where the properties file (deinstall.rsp.tmpl) is saved.
The default location of the properties file depends on the location of the Deinstallation tool:
From the installation media or stage location: <Drive>:\staging_location\deinstall\response
From a unzipped archive file downloaded from OTN: <Drive>:\ziplocation\response, where <Drive>:\ziplocation refers to the location of the downloaded archive file
After installation, from the installed Oracle home: %ORACLE_HOME%\deinstall\response
-help | -h
Use the help option (-help or -h) to obtain additional information about the command options and flags.
If you use the deinstall.bat command located in an Oracle home, or the deinstall.bat command downloaded from Oracle TechNet (not installed in an Oracle home), then it writes log files in the C:\Program Files\Oracle\Inventory\logs directory. If, however, you are using the deinstall.bat command to removed the last Oracle home installed on the server, then the log files are written to:
%TEMP%\OraDeinstall<timestamp>\logs if you use the deinstall.bat command located in the Oracle home
<Drive>:\ziplocation\deinstall\logs if you use the deinstall.bat command downloaded from Oracle TechNet
If you use the separately downloaded version of deinstall.bat, then when the deinstall.bat command runs, you are prompted to provide the home directory of the Oracle software that you want to remove from your system. Provide additional information as prompted.
To run the deinstall.bat command located in an Oracle Database home in the path C:\app\oracle\product\11.2.0\dbhome_1, enter the following command while logged in as a member of the Administrators group:
C:\> cd app\oracle\product C:\app\oracle\product> 11.2.0\dbhome_1\deinstall\deinstall.bat
In the following example, use the deinstall.bat command in the path C:\app\oracle\product\deinstall to deinstall the Oracle home using a parameter file in the software owner location C:\user\oracle:
C:\> cd app\oracle\product\deinstall C:\deinstall> deinstall -home C:\app\oracle\product\11.2.0\dbhome_1 -paramfile C:\user\oracle\my_db_paramfile.tmpl
The following is an example of a parameter file, in which the Oracle Database home (Oracle home) is in the path C:\app\oracle\product\11.2.0\dbhome_1, the Oracle base (where other Oracle software is installed) is C:\app\oracle, the central Oracle Inventory home (oraInventory) is C:\Program Files\Oracle\Inventory, the virtual IP address (VIP) is 192.0.2.1, the local node (the node where you are running the deinstallation session from) is node1, and the remote node is node2:
