Troubleshooting
Problem
When attempting to build a cube that uses Transformer connecting to Cognos Analytics Cloud instance, receive error:
CCL-BIT-0006 The connection closed before the request is processed. If you are using WebSphere Application Server, to reduce the frequency of this error, increase the Persistent Timeout parameter for the Web container transport chains in the administrative console. Increase the time in 10-15 second intervals until the error no longer or rarely occurs.
Symptom
Cube build logs indicate this is happening during the "Read data source" step.
Cube build logs might indicate that only a certain number of records are read in before error happens.
