Uninstalling IBM MQ

Stop, and then uninstall IBM® MQ, including removing any queue managers and their objects. At the end of this task, you are ready to reinstall IBM MQ.

About this task

This task describes the steps for uninstalling IBM MQ on Windows by using the downloaded installation image.

The Getting started scenario takes you through options for installing IBM MQ by using the launchpad or command line. Although you can have more than one installation of IBM MQ, this scenario is based on a new installation on a single server. Therefore, if you want to repeat the scenario, or try out a different installation method, you must first uninstall the existing IBM MQ components, including any existing queue managers and their objects, so that you can start again with a fresh installation.

You might also need to uninstall so that you can carry out a fresh installation for some of the other scenarios in this section.
