You have successfully installed Oracle Clusterware, and you want to remove the Oracle Clusterware installation, either in an educational environment, or a test environment.
You have encountered errors during or after installing or upgrading Oracle Clusterware, and you want to reattempt an installation.
Your installation or upgrade stopped because of a hardware or operating system failure.
You are advised by Oracle Support to reinstall Oracle Clusterware.
If you have an Oracle Database installation using Oracle Restart (an Oracle Grid Infrastructure installation for a standalone server), and you want to configure that server as a cluster member node, then complete the following tasks:
Inspect the Oracle Restart configuration with the Server Control (SRVCTL) utility using the following syntax, where
db_unique_name is the unique name for the database, and
lsnrname is the name of the listener for the database:
srvctl config database -d db_unique_name srvctl config service -d db_unique_name srvctl config listener -l lsnrname
Write down the configuration information for the server, because you will need this information in a later step.
Stop all of the databases, services, and listeners that you discovered in step 1.
If present, unmount all Oracle ASM Cluster File System (Oracle ACFS) file systems.
Go to the directory
\crs\install, where Grid_home is the location of your Oracle Grid Infrastructure home (Grid home) directory, for example:
C:\> cd app\11.2.0\grid\crs\install
C:\..\install> C:\app\11.2.0\grid\perl\bin\perl.exe roothas.pl -deconfig
Prepare the server for Oracle Clusterware configuration, as described in either Chapter 1, "Typical Installation for Oracle Grid Infrastructure for a Cluster" or Chapter 2, "Advanced Installation Oracle Grid Infrastructure for a Cluster Preinstallation Tasks".
If you are using Oracle Grid Infrastructure release 18.104.22.168 or higher, then, as the Oracle Grid Infrastructure installation owner, run Oracle Clusterware Configuration Wizard. Save and stage the response file. For the
-responseFile parameter, specify the full path name where the response file should be written by the Oracle Clusterware Configuration Wizard, for example:
C:\..\crs> cd ..\config C:\..\config> config.bat -silent -responseFile C:\user\dba1\scripts\GI.rsp
If you are using Oracle Grid Infrastructure release 22.214.171.124, then configure the cluster using a response file as described in Appendix B, "Installing and Configuring Oracle Grid Infrastructure Using Response Files."
Mount the Oracle ASM disk group used by Oracle Restart.
If you used Oracle ACFS with Oracle Restart, then mount all Oracle ACFS file systems manually.
Add back Oracle Clusterware services to the Oracle Clusterware home, using the information you wrote down in step 1:
Register the Oracle ACFS resources. Use a command similar to the following, where
Grid_home is the location of your Oracle Grid Infrastructure installation:
C:\> Grid_home\bin\srvctl add filesystem -d \\.\ORCLDATADISK4 -g ORestartData -v db1 -m C:\app\11.2.0\grid\db1 -u grid
Register the Oracle Database resources with Oracle Clusterware. Use the following command syntax, where
db_unique_name is the unique name of the database on the node, and
nodename is the name of the node:
srvctl add database -d db_unique_name -o %ORACLE_HOME% -x nodename
For example, for the database name
mydb on the local node
node1, first verify that the
ORACLE_HOME environment variable is set to the location of the database home directory, then enter the following command to register the database with Oracle Clusterware:
srvctl add database -d mydb -o %ORACLE_HOME% -x node1
Register each database service, using the command
srvctl add service. For example, if your database name is
mydb and you created a service named
myservice for this database, then enter the following command:
srvctl add service -d mydb -s myservice
With release 126.96.36.199 and later, after installing Oracle Grid Infrastructure for a cluster, if you need to change the location of the Grid home, then use the following steps as a guide to detach the existing Grid home, and to attach a new Grid home that uses the new location:
Caution:Before changing the Grid home, you must shut down all executables that run in the Grid home directory that you are modifying. In addition, shut down all applications that use Oracle shared libraries.
Detach the existing Grid home by running the following command as an Administrator user, where
C:\app\11.2.0\grid is the existing Grid home location:
C:\> cd app\11.2.0\grid\oui\bin C:\..\bin> detachhome.bat -silent -local
Move the installed files for Oracle Grid Infrastructure from the old Grid home to the new Grid home. For example, if the old Grid home is
C:\app\11.2.0\grid and the new Grid home is
C:\app\grid, use the following command:
C:\> xcopy C:\app\11.2.0\grid C:\app\grid /E /I /H /K
Clone the Oracle Grid Infrastructure installation, using the instructions provided in "Creating a Cluster by Cloning Oracle Clusterware Step 3: Run the clone.pl Script on Each Destination Node," in Oracle Clusterware Administration and Deployment Guide.
When you run the
clone.pl script in the
\clone\bin directory, provide values for the input parameters that provide the path information for the new Grid home.
Enter the following command to start Oracle Clusterware in the new home location:
C:\..bin\> cd C:\app\grid\crs\install C:\..install\> perl rootcrs.pl -patch -destcrshome C:\app\grid
Repeat steps 1 through 4 on each cluster member node.
You must reconfigure Oracle Clusterware and Oracle ASM every time you move the Grid home.
rootcrs.pl command with the flags
-force enables you to deconfigure Oracle Clusterware on one or more nodes without removing the installed software. This feature is useful if you encounter an error on one or more cluster nodes during installation, such as incorrectly configured shared storage. By running
rootcrs.pl -deconfig -force on nodes where you encounter an installation error, you can deconfigure Oracle Clusterware on those nodes, correct the cause of the error, and then run
Note:Stop any databases, services, and listeners that may be installed and running before deconfiguring Oracle Clusterware.
Caution:Commands used in this section remove the Oracle Grid infrastructure installation for the entire cluster. If you want to remove the installation from an individual node, then refer to Oracle Clusterware Administration and Deployment Guide.
To deconfigure Oracle Clusterware:
Log in using a member of the Administrators group on a node where you encountered an error during installation.
Change directory to
\crs\install. For example:
C:\> cd C:\app\11.2.0\grid\crs\install
rootcrs.pl with the
-deconfig -force flags. For example:
C:\..\install> perl rootcrs.pl -deconfig -force
Repeat on other nodes as required.
If you are deconfiguring Oracle Clusterware on all nodes in the cluster, then on the last node, enter the following command:
C:\..\install> perl rootcrs.pl -deconfig -force -lastnode
-lastnode flag completes deconfiguration of the cluster, including the Oracle Cluster Registry (OCR) and voting disks.
-forceflag must be specified when running the
rootcrs.plscript if there exist running resources that depend on the resources started from the Oracle Clusterware home you are deleting, such as databases, services, or listeners. You must also use the
-forceflag if you are removing a partial, or failed installation.
deinstall tool removes Oracle Clusterware and Oracle ASM from your server. The following sections describe the command, and provide information about additional options to use with the command:
The Deinstallation tool (
deinstall.bat) stops Oracle programs, and removes Oracle software and configuration files on the operating system. The Deinstallation tool is available in Oracle home directories after installation as
%ORACLE_HOME%\deinstall\deinstall.bat. The Deinstallation tool command is also available for download from Oracle Technology Network (OTN) at the following URL:
You can download the Deinstallation tool with the complete Oracle Database 11g Release 2 software, or as a separate archive file. To download the Deinstallation tool separately, click the See All link next to the software version.
The Deinstallation tool 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 command stops Oracle software, and removes Oracle software and configuration files on the operating system for a specific Oracle home. If you run the Deinstallation tool to remove an Oracle Grid Infrastructure for a cluster installation, then the tool prompts you to run the
rootcrs.pl script as a user that is a member of the Administrators group.
Caution:When you run the
deinstallcommand, if the central inventory contains no other registered homes besides the home that you are deconfiguring and removing, then the Deinstallation tool removes the following files and directory contents in the Oracle base directory of the Oracle RAC installation owner:
Oracle strongly recommends that you configure your installations using an Optimal Flexible Architecture (OFA) configuration, and that you reserve Oracle base and Oracle home paths for exclusive use of Oracle software. If you have any user data in these locations in the Oracle base that is owned by the user account that owns the Oracle software, then the
deinstall command deletes this data.
The Deinstallation tool uses the following syntax, where variable content is indicated by italics:
deinstall.bat [-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
Note:You cannot use the Deinstallation tool with the
-localoption for a shared Oracle home.
The default method for running the Deinstallation tool is from the
deinstall directory in the Grid home. In addition, you can run the Deinstallation tool from other locations, or with a parameter file, or specify options when running the
deinstall.bat command. See
The options you can use with the
deinstall.bat command are:
Use this flag to indicate the home path of the Oracle home to check or deinstall. To deinstall Oracle software using the
deinstall.bat command located in the Oracle home being removed, provide a parameter file in a location outside the Oracle home, and do not use the
If you run deinstall from the
\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
Use this flag to run the command in noninteractive mode. This option requires one of the following:
A working system that the Deinstallation tool can access to determine the installation properties
A properties file that contains the configuration values for the Oracle home that is being deinstalled or deconfigured
To create a properties file, modify the template file
deinstall.rsp.tmpl, located in the
response folder of the Deinstallation tool home or the Oracle home.
If you have a working system, you can generate a properties file to use or modify by running the
deinstall.bat command with the
-checkonly flag. The
deinstall.bat command then discovers information from the Oracle home to deinstall and deconfigure. It generates the properties file, which you can then use with the
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. This flag generates a properties file that you can use with the
When you use the
-checkonly flag 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, press Enter at each prompt.
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 only on the local node (the node on which you run
deinstall.bat) for non-shared Oracle home directories.
This flag can only be used in cluster environments.
You cannot use the Deinstallation tool with the
-local option for a shared Oracle home.
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. If you are running the deinstall.bat command from the Oracle home that you plan to deinstall, then you do not need to use the
The default location of the parameter file depends on the location of the Deinstallation tool:
From the installation media or stage location:
From a unzipped archive file downloaded from OTN: <Drive>:\ziplocation\
response, where <Drive>:\ziplocation refers to the directory in which the downloaded archive file was extracted.
After installation, from the installed Oracle home:
value . . .]
Use this flag with a parameter file to override one or more values in a parameter file that you created.
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:
Extracted from an archive file downloaded from OTN: <Drive>:\ziplocation\
response, where <Drive>:\ziplocation\ refers to directory in which the downloaded archive file was extracted.
After installation, from the installed Oracle home:
Use the help option (
-help) to obtain additional information about the command option flags.
If you use the
deinstall.bat command located in an Oracle home, or the
deinstall.bat command downloaded from OTN (not installed in an Oracle home), then it writes log files in the
logs directory. If, however, you are using the
deinstall.bat command to remove the last Oracle home installed on the server, then the log files are written to:
\logs if you use the
deinstall.bat command located in the Oracle home
logs if you use the
deinstall.bat command downloaded from OTN, where <Drive>:\
ziplocation\ refers to directory in which the downloaded archive file was extracted
You can use the Deinstallation tool (
deinstall.bat) to remove failed or incomplete installations. It is available as a separate download from the Oracle Technology Network (OTN) web site.
To download the Deinstallation tool:
Go to the following URL:
Read and accept the OTN license agreement.
Under Oracle Database 11g Release 2, click See All for the respective platform for which you want to download the Deinstallation tool.
The Deinstallation tool is available for download at the end of this page.
Oracle recommends that you run the
deinstall command as the user that installed Oracle Grid Infrastructure (
grid user) or as an Administrator user.
After downloading the Deinstallation tool, ensure that:
The user running the Deinstallation tool is the same on all cluster member nodes
User equivalence is set up
To run the Deinstallation tool, follow these steps:
Download or copy the Deinstallation tool to the
grid user home directory.
Run the Deinstallation tool.
This section provides examples of using the Deinstallation tool to remove Oracle Grid Infrastructure software.
The most common method of running the Deinstallation tool is to use the version installed in the Oracle home being removed. The Deinstallation tool determines the software configuration for the local Oracle home, and then provides default values at each prompt. You can either accept the default value, or override it with a different value. If the software in the Oracle home is not running (for example, after an unsuccessful installation), then the Deinstallation tool cannot determine the configuration, and you must provide all the configuration details either interactively or in a properties file.
To use the Deinstallation tool located in the Oracle home directory, issue the following commands, where
C:\app\11.2.0\grid is the location of Grid home:
To run the
deinstall.bat command located in an Oracle Database home in the path
C:\app\11.2.0\grid, enter the following command while logged in as a member of the Administrator group:
C:\> cd app\ C:\app\> 11.2.0\grid\deinstall\deinstall.bat
To completely remove the Oracle Database installation, you must run the
deinstall.bat command from a prompt that is located outside of the Oracle home. If you run the
deinstall.bat command after changing into the
\deinstall directory, then the Deinstallation tool will not be able to remove all the Oracle software files and directories.
If you use the separately downloaded version of the Deinstallation tool, then when the
deinstall.bat command runs, it uses the information you provide to determine the system configuration and then provides default values at each prompt. You can either accept the default value, or override it with a different value. If the software in the specified Oracle home is not running (for example, after an unsuccessful install attempt), then the Deinstallation tool cannot determine the configuration, and you must provide all the configuration details either interactively or in a properties file.
If your Oracle Grid Infrastructure for a cluster home is
C:\app\11.2.0\grid, then enter the following command while logged in as a member of the Administrators group to remove the Oracle Grid Infrastructure installation from your cluster:
C:\> app\deinstall\deinstall.bat -home C:\app\11.2.0\grid
Provide additional information as prompted. When using the Deinstallation tool from a location other than within the Oracle home being removed, you must specify the
-home option on the command line.
To run the
deinstall.bat command located in an Oracle Grid Infrastructure home and use a parameter file located at
paramfile4.tmpl, enter the following commands while logged in as a member of the Administrators group:
C:\> cd app\11.2.0 C:\> grid\deinstall\deinstall.bat -paramfile C:\users\oracle\paramfile4.tmpl
You can generate the a parameter file by running the
deinstall.bat command with the
-o flags before you run the command to deinstall the Oracle home, or you can use the response file template and manually edit it to create the parameter file.
To generate the parameter file
deinstall.bat command located in the Oracle home and the
-checkonly flag, enter a command similar to the following, where
C:\app\11.2.0\grid is the location of the Grid home and
C:\users\oracle is the directory in which the generated parameter file is created:
C:\> app\11.2.0\grid\deinstall\deinstall -checkonly -o C:\users\oracle\
You can run the
deinstall command with the
-paramfile option. When you use this option, the Deinstallation tool uses the values specified in the parameter file and, if needed, prompts you to supply any missing information.
The following is an example of a parameter file for a cluster on nodes
