CPU and Memory settings to prevent overload in QlikView Distribution Service (QDS)

QlikView includes two settings for the Distribution service configuration file, which allows configuring a setting similar to the QlikView Server Working Set Limit and CPU Affinity settings. The settings are designed to assist with performance tuning of the environment and with load protection. 

Once the overload limit % or either CPU or RAM usage has been reached, the machine is considered overloaded and no further tasks will be executed and the tasks are queued.

Once the % drops below the value, the machine will once again be considered for reloads.

The settings can be managed by editing the QVDistributionService.exe.config file located by default in C:\Program Files\QlikView\Distribution Service.  The two new settings with their explanations are as follows:

 

<!-- If the CPU usage % goes above this value the machine is considered overloaded and no new tasks will be started. -->
<add key="CpuOverloadLimit" value="75"></add>
<!-- If the memory usage % goes above this value the machine is considered overloaded and no new tasks will be started. -->
<add key="MemoryOverloadLimit" value="90"></add>

 

 

Modifying these values may lead to the consequential task and reload failures. While they can be modified, we suggest to allow the operating system and QlikView Distribution service to manage load as recommended.
