v Uninstallation of specific features
If you select this option, you will be prompted to select the database server
features that you want to remove.
3. Follow the prompts in the uninstallation application.
Uninstalling an Informix server installation in silent mode
You can create a response file by recording a GUI-based, interactive uninstallation
of IBM Informix from one location using settings in the GUI application that you
want to replicate. Then you run the silent uninstallation command passing the
response file, although a response file is not necessary if you do not have a
customized installation to deploy.
To create the response file, you must have an installation that you can uninstall in
a way that you plan to reuse for removal of other installations. It is not possible to
do a silent uninstallation of Informix and any of the client products
simultaneously.
If you already have a response file that is ready for silent uninstallation, skip to
step 2
To uninstall Informix in silent mode with a response file:
1.
On a command line, start a GUI uninstallation of Informix with the -r option
in the script:
uninstall\uninstall_server\uninstallserver -i gui -r path_name
Substitute path_name with full path and file name of where you want to
generate the response file, appending .properties at the end of the file name.
2. Copy the response file to the location where you want to uninstall Informix.
3. Run the silent uninstallation command, indicating the full path name of the
response file:
uninstall\uninstall_server\uninstallserver -i silent -f path_name
4. For each location where you want to do a silent uninstallation, repeat steps 2
and 3
