How to uninstall multiple installations of the Integration Bus component

If you install the same version and release of the Integration Bus component on a single computer (for example, Version 9.0) more than once, the installer support provided by the operating system cannot manage these installations in the normal way.

If you later want to uninstall one of the multiple installations, use the uninstallation program uninstaller in the Uninstaller directory of the specific installation that you want to remove, not the facilities provided by the operating system.

You can view the install.properties file to see current installations and their locations, and check the operating system representation:

AIX®

The first installation is recorded as mqsivr, for example mqsi90. Subsequent installations at the same vr level are displayed under the first one when you list installed products with lslpp. If you use smitty and geninstall to manage those subsequent installations, results are unpredictable.

Linux, HP-UX, and Solaris

The first installation is recorded as mqsi/vr, for example mqsi/90. Subsequent installations at the same vr level are recorded as mqsi/vr-2, and so on.

Windows

The most recent installation that you completed for any given version and release is displayed in Add/Remove Programs. No other installations are shown here. Similarly, the Command Console option in the Start menu is that associated with the most recent installation for any given version and release.

If you uninstall the product at a specific version and release listed by Add/Remove Programs, earlier installations that you completed on the computer are not reinstated in that view.

To uninstall other instances, navigate to the directory that contains the uninstallation program. For details of uninstallation tasks, see the information center.
