The DE Server shutdown when the number of active application generations reaches 600.  


Release: DSWAHA01300-12-Workload Automation DE-High Availability


By default DE server is set to shutdown when the number of active generation reaches 600.  By definition, any application that is not complete is considered active. Therefore, it is important to regularly monitor for failed applications and take corrective action or force complete the application to prevent the active application count from reaching this value. 

Based on your workload, it might be necessary to update the maximum active application generation count. If your workload requires much larger value than 600, you can increase the value and some other parameters might require adjustments. For example, Max heap size, number of database connections, increase in thread pool size, etc.


Follow these steps to update the maximum active application generations stop value:

  1. Open in <install_directory>\conf directory
  2. Increase the property 'active.appl.gen.stop' value, for example;


  1. Restart DE Server
  2. Force complete any failed application generation that are active and not needed or suspend any Events triggering failed applications generations
  3. Optional: reset active application count to previous value by stopping the server and repeating steps 1 - 3.
