Uninstalling the Web Server Plug-ins using response files

You can uninstall the Web Server Plug-ins using Installation Manager response files.

Before you begin

Removing the plug-ins will break communication between any web servers and their associated application servers. Be sure to unconfigure any web and applications servers that are using these plug-ins before uninstalling them.

Optional: Perform or record the installation of Installation Manager and installation of the Web Server Plug-ins to a temporary installation registry on one of your systems so that you can use this temporary registry to record the uninstallation without using the standard registry where Installation Manager is installed.

About this task

Using Installation Manager, you can work with response files to uninstall the Web Server Plug-ins in a variety of ways. You can record a response file using the GUI as described in the following procedure, or you can generate a new response file by hand or by taking an example and modifying it.

Procedure

Optional: Record a response file to uninstall the Web Server Plug-ins: On one of your systems, perform the following actions to record a response file that will uninstall the Web Server Plug-ins:
1. From a command line, change to the eclipse subdirectory in the directory where you installed Installation Manager.
2. Start Installation Manager from the command line using the -record option.
  For example:
  - Administrator or non-administrator:
    IBMIM.exe -skipInstall "C:\temp\imRegistry" -record C:\temp\uninstall_response_file.xml
  - Administrator:
    ./IBMIM -skipInstall /var/temp/imRegistry -record /var/temp/uninstall_response_file.xml
  - Non-administrator:
    ./IBMIM -skipInstall user_home/var/temp/imRegistry -record user_home/var/temp/uninstall_response_file.xml
  Tip: If you choose to use the -skipInstall parameter with a temporary installation registry created as described in Before you begin, Installation Manager uses the temporary installation registry while recording the response file. It is important to note that when the -skipInstall parameter is specified, no packages are installed or uninstalled. All of the actions that you perform in Installation Manager simply update the installation data that is stored in the specified temporary registry. After the response file is generated, it can be used to uninstall the Web Server Plug-ins, removing the Web Server Plug-ins files and updating the standard installation registry.
  The -skipInstall operation should not be used on the actual agent data location used by Installation Manager. This is unsupported. Use a clean writable location, and re-use that location for future recording sessions.
  
  For more information, read the IBM Installation Manager documentation.
3. Click Uninstall.
4. In the Uninstall Packages window, perform the following actions.
  1. Select Web Server Plug-ins for IBM WebSphere Application Server and the appropriate version.
    Note: If you are uninstalling the ILAN version of this product, select Web Server Plug-ins for IBM WebSphere Application Server (ILAN).
  2. Click Next.
5. Review the summary information.
6. Click Uninstall.
  - If the uninstallation is successful, the program displays a message that indicates success.
  - If the uninstallation is not successful, click View log to troubleshoot the problem.
7. Click Finish.
8. Click File > Exit to close Installation Manager.
Use the response file to uninstall the Web Server Plug-ins: From a command line on each of the systems from which you want to uninstall the Web Server Plug-ins, change to the eclipse/tools subdirectory in the directory where you installed Installation Manager and use the response file that you created to uninstall the Web Server Plug-ins.
For example:
- Administrator or non-administrator:
```
imcl.exe 
  input C:\temp\uninstall_response_file.xml 
  -log C:\temp\uninstall_log.xml
```
- Administrator:
```
./imcl
  input /var/temp/uninstall_response_file.xml 
  -log /var/temp/uninstall_log.xml
```
- Non-administrator:
```
./imcl
  input user_home/var/temp/uninstall_response_file.xml 
  -log user_home/var/temp/uninstall_log.xml
```
Go to the IBM Installation Manager documentation for more information.
Optional: List all installed packages to verify the uninstallation.
```
./imcl listInstalledPackages
```
```
imcl listInstalledPackages
```

Example

The following is an example of a response file for uninstalling the Web Server Plug-ins with a 32-bit SDK.

<?xml version="1.0" encoding="UTF-8"?>

</uninstall>
<profile id='Web Server Plug-ins for IBM WebSphere Application Server V8.5' 
  installLocation='C:\Program Files\IBM\WebSphere\Plugins'>
<data key='eclipseLocation' value='C:\Program Files\IBM\WebSphere\Plugins'/>
<data key='user.import.profile' value='false'/>
<data key='cic.selector.nl' value='en'/>
</profile>
</agent-input>
