Additional Windows features prerequisite checking

There are two Windows installation features that have additional prerequisite checking enabled in the Windows IBM MQ installer from IBM MQ Version 9.0.2. These are the Server feature and the Java Runtime Environment (JRE) feature. These features are required by other features and installing those features, without these prerequisite checks, would cause those features to be unusable.

If you perform a Graphical User Interface installation, and select the custom install option, we can deselect the JRE or Server features.Attention: Dialog panels prevent you from completing the installation, until you have resolved any issues.

If you perform a silent installation, and you elect to REMOVE the Server or JRE features while installing any other features that require those features, the Server and JRE features, as appropriate, will be added to your selected installation features.

Table Table 1 describes how the selection of certain installation features requires the Server or JRE to be added automatically.

Table 1. Installation features requiring either the Server or JRE feature

To check whether the JRE or Server features have been installed, look in the [INSTALLDIR]\swidtag directory. If the:

• ibm.com_IBM_MQ-9.0.x.swidtag file is present, the Server has been installed
• IBM_MQ_JRE-1.8.0.mqtag file is present, the JRE has been installed.

If this is not what you require, consult the installation log. Important: Each of the JRE and Server features are part of the set of Windows standard IBM MQ installation features. To remove the JRE (or the Server) when installing silently, add the feature to the REMOVE directive, do not merely omit it from the ADDLOCAL directive. See Windows standard installation features for further details.
