Error retrieving results
Often I get the error message "Error retrieving results" when I open a report in the morning. Every night the Tomcat is restarted.
When I go to data sources and open / save the specific data source; open the report again. The problem is gone and the report shows the results.
We have a lot of data marts stored in about 14 different data sources.
We did not customize any XML's or configs.
How can we keep this connection 'alive'?
