QlikView Server Unbalanced Clustering when using IIS as web server

The QlikView 12 Help regarding configuration of an unbalanced QlikView Server cluster located here:

https://help.qlik.com/en-US/qlikview/November2017/Subsystems/Server/Content/QlikView-Server/QVSRM_Unbalanced_Clustering.htm

is missing information regarding how to complete the configuration if IIS is being used as the web server in the environment.

Missing documentation, which has been submitted to R&D to correct via case QV-13524.

Find the QVWebServerSettingsService.exe.config file in the default location of C:\Program Files\QlikView\Server\Web Server Settings on the server(s) running the IIS services and place the following lines of code between the <appSettings> and </appSettings> tags and then restart the QlikView Settings Service for the change to be picked up.

        <add key="UnbalancedClusterLoadBalancer" value="false"></add>
        <!-- The CPU weight signals how much impact the CPU performance should have while picking QVS to open doc -->
        <add key="UnbalancedClusterLoadBalancerCpuWeight" value="5"></add>
        <!--The RAM weight signals how much impact the RAM performance should have while picking QVS to open doc -->
        <add key="UnbalancedClusterLoadBalancerRamWeight" value="3"></add>
        <!-- The Loaded Document weight signals how much impact a a already loaded document should have while picking QVS to open doc -->
        <add key="UnbalancedClusterLoadBalancerLoadedDocWeight" value="3"></add>

You will need to change the value for the UnbalancedClusterLoadBalancer from the default value of "false" to "true" and you may need to adjust the other settings as well, but initially it is best to leave those as they are in the default state.
