The operation has timed out error

If a data slice is too large, an operation, such as defining a dataset or loading a dataset, can time out if it takes too long to return from the server.

To avoid this error, select fewer members or extend the server timeout limit to a maximum of 10 minutes, 600 seconds.

To extend the server timeout:

  1. In a text editor, open the web.config file from the \ComshareWeb\Services\CBRService directory.
  2. Add the following line to the end of the web.config file, immediately preceding the </system.web> line: 
    <httpRuntime executionTimeout="600"/>
  3. Optionally, you can reduce the timeout from 600 to a lower number if you prefer the server to time out sooner when data slices are too large. Do not, however, exceed 600, the value set for the server timeout should not exceed the 10-minute client timeout.
  4. Save the web.config file.
