Adding an additional Cognos Node
When the demand for report processing increases, report execution can be scaled up in multiple ways. The least disruptive way is to add an additional Cognos Processing Node into the configuration, which is a dynamic action that does not require a restart of the Content Manager Service.
When a new node is started up, it must be configured to register with the original Content Manager service. The requests coming from Changepoint to the Dispatcher defined in Changepoint are by default balanced between the two nodes in a round-robin fashion.
