You can uninstall (remove) WebSphere MQ client in attended mode or unattended (silent) mode.
Before you uninstall WebSphere MQ client, ensure that there are no WebSphere MQ client programs running.
There are three ways to uninstall WebSphere MQ from your machine:
You can use these methods to uninstall the WebSphere MQ client, as long as the original installation used the WebSphere MQ Client CD.
You can also uninstall WebSphere MQ client by using the appropriate parameters with advanced installation methods, or by using Microsoft(R) System Management Server (SMS). See Advanced installation methods.
This procedure uninstalls WebSphere MQ from your machine in attended mode. It removes all the currently installed features.
Otherwise, double-click the Setup icon in the root folder of the CD to start the installation process.
The Program Maintenance panel is displayed.
If this panel is not displayed, WebSphere MQ for Windows, V6.0 is not installed on this machine.
Click Remove to continue.
Wait for the progress bar to complete.
If there are any messages that state that locked files are found, ensure that there are no WebSphere MQ client programs running.
Uninstallation should then continue.
Uninstallation Completed Successfully
Click Finish.
The uninstall program begins. All the WebSphere MQ files are removed.
This procedure can be used for removing the WebSphere MQ files in unattended (silent) mode.
To invoke an uninstallation, you use the Msiexec command.
To uninstall all WebSphere MQ client features, enter one of the following commands:
This command gives you an interactive uninstallation of all features.
This command invokes a silent uninstall of all features.
This command displays only a progress dialog whilst uninstalling all features.
This command invokes a silent uninstall of all features.
Alternatively, you can the Msiexec command with a parameter that calls a response file. A response file is an ASCII text file that contains the parameter values you want to set for the uninstallation. The response file has a format similar to a Windows .ini file, and contains the stanza [Response]. This stanza contains parameters that the Msiexec command can use, in the form of PROPERTY=value pairs. The Msiexec command ignores any other stanzas in the file.
You can set which features to uninstall.
To uninstall WebSphere MQ using a response file, enter the following command:
Msiexec /i "path\MSI\IBM WebSphere MQ.msi" /q USEINI="response_file"
where response_file is the file that contains the [Response] stanza and the required PROPERTY=value pairs.
An example of a typical uninstallation response file is:
[Response] REMOVE="Client,Toolkit"
