Specify Queue Time Limits

You can specify the maximum number of seconds that interactive requests made by users wait in the queue for an available report service or data movement connection.

If a request cannot be processed within the time limit, the request fails and users receive an error message. If your operating system has adequate resources and IBM® Cognos® software is properly configured, requests should not take longer than the time limit.

When you specify a time limit, consider the maximum number of seconds that you want users to wait for a response. The default queue time limit is 240 seconds.

Requests for the batch report service stay in the queue indefinitely.

If you have a high user load (over 165 users) and interactive reports are running continuously in a distributed installation, increase the queue time limit to 360 to avoid getting error messages. You may also want to increase the asynchronous timeout setting to avoid getting error messages. For more information, see the IBM Cognos Business Intelligence Installation and Configuration Guide.
