Increase Asynchronous Timeout in High User Load Environments

If you have a high user load (over 165 users) and interactive reports are running continuously in a distributed installation, you may want to increase the asynchronous timeout setting to avoid getting error messages. The default is 30000.

You may also want to set the Queue Time Limit setting to 360. For information, see the IBM Cognos Analytics Administration and Security Guide.

To resolve this problem, increase the wait timeout.


  1. Go to the following directory:


  2. Open the reportservice.xml file in a text editor.
  3. Change the async_wait_timeout_ms parameter to 120000.
  4. Save the file.
  5. Restart the service.
